Pump for fountains: artificial heart water source

A real gem of any landscape is a fountain or waterfall. Such a structure completely changes the microclimate surrounding area, enlivens and decorates exterior. To be able to admire and enjoy the flowing water, the pump is required for fountains. This machine is able to create the desired pressure, whereby water rises to the surface and gradually decreases downwards.

Pumps for fountains: Meaning and functionality of the device

The pump is a special device which is mounted on the circuit cyclically surpasses water. Often the equipment is used for the decorative design of hydraulic structures on country estates and suburban areas.

The principle of operation of the fountain pump based on the creation of a positive pressure that pushes the water with a certain force. Power unit determines the height of the buoyant jet. The structure of the pump equipment for the fountain can enter a list of different constituent elements, depending on the device type and its maker. But any set consists of a rotating motor and impeller, affecting power flow.

Garden fountain pump has approximately the packaging:

• motor;
• a motor housing;
• nozzle;
• the telescopic pipe;
• fluid flow controller;
• tap for connection of the waterfall or fountain;
• the pump impeller;
• fountain head;
• spray;
• grid.

Pump for giving different mobility and compact design. The unit is used seasonally. He does not need any additional communications and cope with the movement of water without the need to connect the water supply.

For a country house or villa set circulating devices that operate in a closed mode. Their receiver is located below the water bowls with a fountain. With pump water through the different nozzles is injected into the tube moves up and atomised at a certain height. To work falls liquid rises from the container falls on margins and returns to the reservoir. Such a closed water system can not be achieved without the electric.

The principle of operation of the submersible pump to the fountain to the country

Submersible device is a wet-type centrifugal pump equipment. The housing is made of durable plastic or stainless steel, which is determined by the operating conditions. engine power may be in the 6-100 watt range.

This type of pump is used for small fountains depth of not more than 2 m, and the floating submersible vessels, stationary and wall constructions. The pump is mounted on the bottom of the tank by means of special suction cups, preventing displacement of the machine during its operation. If the device is used for ponds, it is placed on a small plinth brick or concrete to prevent sludge entering the system. Moreover, such a setting is preferable for fountains, as reduced wear of cleaning elements.

The pump body is completely submerged in water. The top element in the form of a special nozzle takes the role of the sprinkler, towering above the water surface at a certain distance. Absorption occurs via the barred lower part of the unit, where the filter is installed. Submersible pumps are characterized by low weight and compact dimensions. The pressure in the system is largely dependent on the section of pipe and supply hoses. The smaller they are, the more intense will be the jet and more water flux.

Useful advice! Periodically the filter is recommended to remove from the body and clean. If it fails, you must immediately be replaced by a new one, because the condition of the filter is directly related to the period of operation of the pump.

Features of the construction of a submersible pump for the pond and fountain

Insertion device produces water from the lower layers of the reservoir or an external source, with subsequent release through the nozzle. In the first embodiment, the pump must be equipped with a filtration system is required to avoid fouling of the system. a jet of water is sprayed on the unit. If the system is retrofitted a hose length of flow can lead to a certain place, that we are given the idea of ​​landscape design. Compound pipes and elongation occurs telescopic principle with rubber or plastic compounds.

Submersible pumps operate practically noiselessly with low power consumption (it requires 30% less than for surface unit). This is due to the fact that the nozzle is located close to the motor, and this contributes to minimal power loss.

It operates the pump from the power supply, so when installing the system it is mandatory to earth. For normal operation of the pump 24 is sufficient voltage V. Such devices belong to the low-voltage units, for which the power source can be a simple transformer.

The greater the tube length and number of additional structural elements, the more power will be consumed. This will require high-power device. It will be connected to the electrical network via a cable that must be covered with a waterproof material.

Submersible pumps are designed for pumping substantially pure water containing no impurities. Intrusion of water impurities in a concentration of 50 g / m³, Whose size does not exceed 0.2 mm. In order to avoid breakages, all pumps are equipped with filters in the form of a stainless mesh with fine mesh, ranging in the suction member of the pump. They retain mechanical impurities, preventing internal pump parts from premature abrasion and wear.

The strengths and weaknesses of the submersible pump for fountains

The advantages of submersible pumps for fountains include the following criteria:

• small cost that is affordable for any summer resident;
• lightness and ease of installation allowing to carry out installation yourself;
• high efficiency;
• minimal power consumption;
• quiet operation, allowing you to enjoy the sound of running water;

• invisibility, which is associated with the installation of the device on the bottom of the tank, eliminating the need to find a suitable place and the subsequent masking unit;
• compact model that is suitable even for small fountains.

Among the disadvantages of submersible pumps for the fountain can be distinguished:

• the complexity of the repair and maintenance, it requires draining the reservoir;
• It requires strict compliance with electrical safety;
• the need to dismantle equipment in winter.

Surface pumps for fountains and waterfalls

surface-type pump units are dry type equipment. They are predominantly used for demanding high multilevel structures. The device is selected when it becomes necessary to connect multiple objects to a single pump. In this case, we focus on the pressure of the different elements and correctly adjust the power level of the stream. When connecting two circuits need to install a tee.

Surface pump has a large size and high cost. It should be located in a dry area in the immediate vicinity of the reservoir, from which the power of the unit and will depend. If long hoses and connecting a large number of sorts of nozzles decreases the efficiency of the device. The maximum allowable distance for normal operation of the unit should not exceed 2 m, as indicated in the instructions.

After installation the unit should disguise that it did not spoil the appearance of the landscape. Such devices are easy to use and maintain, does not require disassembly during wintertime.

Surface aggregates are less sensitive to dirt and organics in the water to. They can pump water from any source. For this purpose it is lowered hose device, which is connected to the inlet of the pump. power cables do not need additional protection that ensures the safe operation of the pump.

Since the structure is located in the open air, should provide adequate protection to it from moisture and direct sunlight. For this purpose, the pump casing is covered with a protective to some extent reduces the noise that the machine emits. Also, under the device can be equipped with a separate box or pavilion, protecting it from rain.

Useful advice! If the water contains large slurry on the suction hose is recommended to install a foot valve with a fine mesh filter.

High pump noise can be distinguished from the device deficiencies that require installing insulation. For this pavilion or a protective housing for the pump is sheathed inside noise absorbing material.

What is a filter set with Fountain Pump

In the construction of the fountain for the pond, be sure to use a filter. It can be a simple, external, placed at the pond UV. The first embodiment is represented as a small block made of a porous material. The product is installed near the grid submersible pump unit. It provides mechanical and biological purification of water at a constant operation.

External filter - a multilayered unit which is attached to the pump by a pipe-entry holes. Water seeps through the mesh or porous filter, where the mechanical cleaning of water. The next layer is made of a porous filter material. At the bottom of the block is perforated base. During continuous operation, the pump is provided by a biological water purification filter in all layers.

The filter that is located at the bottom of the reservoir, is a unit filled with gravel and small fraction porous material for mechanical cleaning.

Contaminated natural ponds most rational solution is to install ultraviolet purifier running on electricity. This unit with a special chamber with lamps, in which the water entering susceptible to ultraviolet radiation. Purified fluid enters the suction conduit of the pump. The main disadvantage of this filter is its high cost.

Pump Selection criteria for the waterfall and the fountain

Choosing pumps for the fountain, should focus on performance, operating voltage, power and height of rising water, which are specified in the device data sheet. The pump must run at a moderate speed, while achieving the required level of power. If the unit will be permanently laid out in full its working life quickly depleted, which would require replacement of the device on more productive.

When selecting a pump power unit should be compared and the size of an artificial pond. jet apparatus height must not exceed the width of the third portion of the reservoir. In order to obtain a height of 1.3 m, you must purchase a pump with a flow rate of 800 l / h. To create a jet height of 2 m the unit must be designed for a capacity of 3000 l / hour.

Electrical power and the determined power supply voltage. Powerful units operate from the power supply 220 V. They are fed through the cable through the RCD and circuit breaker. Low-voltage units can be operated from the mains at 12 and 24 V power supplies are used for them.

Useful advice!For spray fountains it is recommended to give preference to units with high pressure and low productivity, and to waterfalls - low-voltage pump with a high productivity.

An important criterion is the location of the tank placement. For fountains located indoors, it is sufficient to use a low-voltage units 5-8 watts. This is a small quiet devices without creating vibration waves. They are not primarily equipped with a filter, as they deal with clean water. These units have a thin and short power cord without ground. Pumps for fountains and ponds located outdoors must be fitted with filters. It is necessary that the power cable was thick and had a grounding.

Helpful Hints for buying water pump for fountains

When buying the pump should be selected for the fountain assembly with a full set of additional elements, comprising hoses, nozzles, spray heads, water flow regulation system. Not buy them separately would be too expensive and troublesome. The pump should be made of a material resistant to corrosion, which will directly affect the period of operation of the device.

Price submersible pump for a fountain-type is higher than the surface. This is due to the fact that in its manufacture use special materials exhibiting increased resistance to underwater pressure and constant contact with the aqueous medium. On the cost of the device is also influenced by the type and number of component elements, the presence of ultraviolet light and the backlight.

Choosing a pump for the fountain is better to choose a model equipped with such elements:

• tee with a valve through which the water flow can be divided into two terms;
• transition pipe to increase the pressure at the outlet;
• head with LEDs, used for illumination of the fountain, which occurs when installing it on a special threaded extension.

Useful advice! All of the above items can be purchased separately depending on their need.

Features installation of pumps for waterfalls and fountains

Submersible pump for holiday fountain is installed at the bottom of the pond. It is usually mounted on a brick pedestal pillow or plastic. The metal substrate is not suitable to arrange, because the material is not resistant to oxidation, leading to structural failure.

The upper part of the pump must with a plastic or rubber tube connected to the pump. To avoid deformations can take advantage of the corrugated hose. When installing a submersible pump and be careful to observe the water level in the tank. Excessive its drainage can cause damage to the unit, which is associated with insufficient water level in the tank. the unit running dry can lead to irreversible consequences.

Important!Organizing power, have to worry about the proper connection of all the power and performance of the grounding wire harnesses.

Surface pump is installed near the water tank in the box, or pavilion, where it is necessary to provide for its isolation and grounding cable lines. Often the unit housing is further covered with a waterproof casing.

How to make the pump with their own hands for a small fountain

For the organization of a garden fountain you can use a pump of the washing machine. It is connected to the water supply system and power supply. It is important to ensure proper isolation of the unit, to prevent its contact with water.

Pumps for indoor fountains can be made independently of the fan base with illumination. Such a device will operate from a DC network 12 and connected through the power supply to the home network. To charge portable fountain can be from a car battery.

For the manufacture of pumps for home fountain will need the following list of materials:

• Computer fan;
• Plastic container with lid;
• power supply unit 12;
• plastic cup;
• aquarium hose;
• studs M3 and M4 with nuts and washers for them;
• 1.5 mm thick plexiglas;
• M3 screw;
• gel pen;
• Janet syringe to 150 ml;
• aluminum sheet 0.2 mm thick.

The process of making water pump with their own hands

The main element of the pump is a water pump. For its creation, templates are executed. Items must have the exact dimensions for easy ottsentrovki them when assembling pump. All elements are made of aluminum sheet in an amount of 2 pieces. each species. Cut four square 50x50 mm. For the lower plate openings 10 are executed mm diameter for top - 4.5 mm. At the corners of the templates is done symmetrically with holes for pins with a diameter of 3 mm. The distance from the edges to the product center holes must sostavlyat12 mm.

The plexiglass executed hole diameter of 3 mm using heated above the drill flame. Glass is clamped between two identical aluminum templates and secured by means of bolts and nuts. Templates are aligned, after which the opposite corners are drilled in the same manner. Similarly, the lower plate is performed. The edges of the plexiglass cut with a heated knife stationery template. If necessary, they should be cleaned with fine sandpaper.

template by the lid of a plastic container that is a reservoir for water, also performed holes. The central hole of the upper plate is necessary to insert a small piece of a length of 40-50 cm from the stem gel pens, which will play the role of the stuffing box and bearing simultaneously.

To carry out the body using a syringe Janet. It follows from this cut ring height 13 mm and diameter 40 mm. To perform clean cut, you need to use the device: with two bolts and nuts on a flat piece of board is required to attach the blade of the knife stationery, departing from its beginning 13 mm. The blade is heated by means of a soldering iron and over the entire circumference of the syringe is applied the risk at which the office knife incision.

Further knife must perform gel slice rod from the handle at an angle, the size of which is performed a hole in the syringe body. The next stage is the connection of all parts by hotmelt gun.

Manufacture of the pump wheel for the small fountain

To manufacture the impeller cut the blank from a sheet of aluminum: two disks 38.5 mm in diameter and two bands of 6 mm width. In the central part of the circle must perform holes of 4.5 mm diameter and 10 mm. Aluminum strip is slightly bent and applied to the drive to get the blade. They may be 5-6 pieces. The length of the blades is determined on the spot. They are glued to the disk using superglue. On the upper faces of the blades glue is applied and worn plastic housing. Top should be put upper disc. Assembly is placed under the load and held in this position for 30 minutes.

Useful advice! After drying the glue to remove burrs and irregularities of all the edges are processed file.

Further cut stud length exceeding the height of the container. They are screwed the nut and washer are worn. The preferred unit upside down to collect. On stud fits the upper plate of plexiglass with a bearing made from a gel pen. It is fixed at a distance from the edge of the studs 60 mm and fixed with nuts and washers. Then, a large opening is set up impeller. In short it is inserted into the screw hole, which is fixed by the bearing nut.

Assembling all the parts of the pump for the fountain with his own hands

Sealant is applied to the lower end of the plastic body, which fits over the impeller, and is firmly pressed to the plate. After hardening the adhesive verified impeller efficiency, which during rotation must not touch the housing wall.

In the end the plastic casing is applied sealant, which is set lower plate, which is threaded through the holes studs. Details are fixed by means of nuts and washers. The fan must be checked for performance by connecting it to a computer.

Plexiglas cut square of 12x12 mm. In its center a hole is drilled with a diameter of 3 mm, where the screw is inserted so that its head is flush with the plane of the glass. The shaft is mounted on the fan ottsentrovyvaetsya and fixed with a nut. It is fixed using a Melt adhesive which is applied evenly to avoid fracture during operation.

On the bolt should be put on a segment of the rod from the handle and fix with superglue. To cover the container studs need to attach a homemade pump. Also in the threaded hole in the lid of the impeller stranded bolt with a nut, which is fixed with glue rod from the handle.

For fixing the fan must be cut M4 bolts, which are inserted into its hole and fixed with nuts and washers. The motor shaft via a hose connected to the aquarium pump shaft.

Conducting tests improvised pump mini fountain

Primary small pump test water runs dry. For this purpose, the fan is connected to the system power supply unit, and then the inclusion pump. Verified the absence of noise, impact, grinding, and controlled rotation of the impeller speed.

Further testing of the device is performed with water. For this pump in a working position mounted on the liquid container. The effluent from the pump hose is raised to the desired height and fixed. The pump starts to work. According to the level of water in the hose is determined by the height of water column, which characterizes the pump capability. For this device it is equal to 0.5 m.

The next step is the pump capacity check. For this measured amount of water flowing from it into another container during operation of the apparatus for 1 minute. The liquid volume is measured in liters and multiplied by 60.

Important! To create a mini-waterfall with your hands, use a larger volume of the container and ensure the continued operation of the pump with a continuous supply of water in it.

Performing for indoor fountain bowl

Bowl for indoor fountain their hands without pump may be of any desired size container. It bore holes for pins, nozzles and drain into the container. For the last holes of the segments are provided seals rod gel pens. Before mounting studs must be liberally greased with colorless silicone sealant. They put on the cup, which is fixed with nuts. Fixed with a sealant.

From the gel tip pen with writing rod remote performed fountain nozzle. To element is attached the hose from the pump. To drain, attach the hose, place it in the container. To avoid gurgling when draining water to the lower end of the hose is worn tee. The tubes are bred in different directions, but as close as possible to the walls of the plastic container.

After the cup container is filled with water. Check the tightness. Conventional syringe cleaned air bubbles from the pump. By the power supply connects the engine. To this red wire connects to the fan unit plus and black - minus. Signal white insulated wire. The pump is included in the work, and verified its performance. During the test, you should pay attention to the absence of heartbeat and leaks. The lights, and checks operation of the backlight.

For indoor fountain, of course, possible to make the pump by hand. A pond or waterfall is better to use ready-made units from reputable manufacturers. The pumping equipment instructions are written all the technical characteristics of the device, which is necessary to select the unit to perform a specific task.
