Submersible pump for dirty water: universal assistant

Owners of private houses constantly have to solve the problem of accumulation of polluted water. To divert runoff is necessary to use special equipment, which is represented by drainage units. That is a surface or submersible pump for dirty water, how to choose the device and which models are most in demand, we can learn from this article.

Field of use of pumps for pumping water containing impurities

Pumps for pumping dirty water used for draining the storage containers, silted wells, reservoirs, wells, accumulated moisture to drain during flooding. They are also used in case of emergency when it is necessary to pump water from the flooded cellar or basement. Submersible pumps are often used on construction sites for the diversion of precipitation, ground water from pits and trenches.

Mud pumps can be safely used for pumping liquid from one container to another for the purpose of its further use for watering land. Units also exploited for irrigation of greenhouses and gardens.

Modern mud pump for pumping water can be used for drainage wells from sand mines and silt, pumping "flowering" of water from open water bodies, the regeneration of the drain system. Due to the special internal structure aggregates capable of passing solid particles and small fibers stones, which makes tools universal, indispensable for the implementation of economic tasks.

When choosing the drainage unit should be based on the level of contamination of the fluid to be pumped. Pumps for low contaminated waters are designed for transporting fluid from the powders of size 5 mm. Their performance reaches 80-230 l / min, pressure -.. Such aggregates 5-12m used for water intake from the wells, drainage basins, pumping water from the rainwater tanks. This category also includes pumps for pumping water from the tank.

For drainage wells and stormwater drainage pumps are used for pumping liquids normally soiled with particles of size up to 25 mm, their performance -. 40-450 l / min, pressure -. 5-22 m wastewater pump capable of pumping fluid suspensions with diameter 38-40 mm. Performance of such machines is 50-600 l / min.

Submersible pumps are used for pumping waste water sewer. For this purpose fecal units equipped with special shredders for large debris that affect the rise in price of the unit.

Design features of the drain pump dirty water

Vacuum pumps for pumping water carried in metal or plastic housing, which provides portability and ease of use. Plastic exhibits greater sensitivity to the solid particles, and therefore characterized by a smaller period of operation.

Inside the housing are arranged a pump and motor assembly. The working elements are the last rotor, the stator and bearing shields. An impeller, which is called an impeller, is planted on the rotor shaft. Both elements are made of stainless steel. The impeller shaft can be located on the engine itself or separately from it. The pump unit equipped with the delivery pipe with holes, the diameter of which corresponds to the size of solid particles which are able to skip unit.

Useful advice! If a pump for pumping water from the pool, basement or cellar is rarely used, the hoses must be rigid, as if often, then it is better to use flexible pipes.

To all the driving mechanisms of the pump unit to work smoothly and safely, the unit is equipped with a thermostat to turn off the unit in case of engine heating to the critical condition and float switch which monitors the fluid level in the reservoir and shuts down the unit at the minimum value.

How does the drain pump for dirty water with a float

When the motor shaft with the impeller to rotate. The housing unit creates a vacuum around the rotating blades. Under vacuum action the liquid is sucked into the working chamber and ejecting it under the influence centrifugal force to the outside through the outlet pipe, which is carried out under the influence of established pressure.

Pump out water simultaneously cools the engine, thus eliminating the likelihood of overheating of the pump in continuous operation of the unit. However, with this drainage pumps can pump fluid, whose temperature does not exceed 50 ° C.

Important! There are special expensive models of drainage pumps which can pump a liquid having a temperature above 50 ° C.

Float switch represented by a set of sensors that are placed in a sealed polymer case. Thanks to the electric switch and the steel ball comes to open and close contacts of the circuit when the float changes its position. Inside the box is the air. He, as a float, is always located on the surface, following the water level.

There are new borehole pumps for dirty water, equipped akvasensor technology used when pumping fluid from the narrow tanks, where it is not possible to arrange the float switch. With such devices, you can set a minimum water level at which the device is turned off. It can be as low as 5 mm.

Feature of surface pumps the dirty water

Surface self-priming pumps the dirty water tank installed close to or with the water tank. The pump housing must be placed on a flat surface dry. The unit is equipped with two hoses. The suction pipe of PVC is lowered into a liquid, it serves to its intake from the source. The hose must be durable and resistant to deformation. The output provides the penstock diversion of water outside the building.

Surface pump can operate in automatic mode. For this purpose the float mechanism of the pump unit is connected to the tumbler, which is triggered at the time of reaching the minimum water level in the tank.

The main advantages of surface pumps for pumping water are simplicity of design, ease of installation and removal, simple tastes to low maintenance, efficiency and durability operation. The device has a compact size, making it easy to move, transport and store. Due to the fact that the pump body is not located in water, surface aggregates are characterized by low level of wear elements of the mechanism.

Important! Surface drainage pump is ideal for seasonal use.

This pump works pretty quiet, especially when it relates to a device in a plastic case. Metal unit during operation is buzzing. To reduce noise, it is recommended to place the pump on a platform with a rubber mat. Surface pumps are characterized by a democratic value that depends on the specific model and manufacturer.

It should be remembered that the surface aggregates can not be used for raising the water at a significant depth. Maximum suction height of 8-12 m. The farther the unit is located on the place of water intake, the lower its suction capacity. To this end, it should be placed as close as possible to the source.

Important! If the pump unit is connected to the sewage network, you must know exactly the diameter of the pipe, as the connection made through the use of pipe must be sealed.

Drain submersible wastewater pump with integrated float

The large demand for household uses, according to many reviews, the submersible pump to the dirty water. The unit is intended for location directly into the water column. It can be completely lowered into the liquid or partially peek therefrom. water from a source of pump unit is carried out directly without the intervention of the suction pipe.

Suction valves may be arranged on the top or bottom of the unit housing. The first option is more durable devices because such an arrangement minimizes the risk of damage to the working chamber as a result of falling larger particles. The second type of operational reliability of devices are better placed on a special stand. On the bottom of the unit is a screen, which protects the internal structural elements of the impact of large solid particles and debris.

Submersible unit should be used if required to pump dirty water with a significant depth of up to 50 m. For small reservoirs and water depths less than 20 m such a pump is not used follows. This is due to the fact that during operation of the device is a constant cooling of the engine because the pump is immersed in the water a longer period.

Important! If it is necessary to use a submersible pump for taking water from the shallow source, it is necessary to arrange extra cooling water of the motor.

Depth of installation of the device is determined tank type. It should be borne in mind that the lower the pump is omitted, the effectiveness of its work.

The main advantages of drainage submersible pumps are high power and performance aggregates in comparison with surface analogs, the possibility of sampling water and complete drainage of deep wells and vessels, resistance to temperature changes, to aggressive substances which may be present in the dirty water. As mentioned in many reviews, submersible pumps for dirty water run almost silently, without causing vibrations.

The main disadvantage of submersible pump is considered to be the need for its removal for maintenance and repair. Organized by the tightness of the case makes it difficult to perform scheduled preventive works.

Submersible pump for dirty water: particular use of the machine

Submersible Electropomp dirty water run continuously in an automatic mode, which is performed due to the presence of the float mechanism which is connected to the power tumbler. He cuts off the motor when it reaches the minimum water level in the building. Due to this mode of operation the pump can be permanently installed in a pit or well. It will periodically turn on when the tank is full.

Important! For automatic pump adequate protection and sealing of the motor must be provided, since the unit will be constantly working under water.

Submersible pumps pumping water shall be made of corrosion-resistant material that can withstand significant mechanical stress and damage. The nodal elements may be made of polymers, structural plastic, alloy, carbon steel, electrical alloy, which is determined by the purpose and nature of the perceived loads.

a hand pump for pumping water Characteristics

Hand pump for pumping out the dirty water from the tank or vessel outside the facilities on the principle of action is similar to an electrical machine. The main differences are in the construction features of the device and its operation rate, which depends on the quality of the ongoing efforts.

Hand pumps for pumping water are performed in three varieties - a piston, vane and hose assemblies. The first embodiment is represented as a cylinder equipped with a piston. Located inside the valve-opening, and at the bottom of the cylinder is placed the disk.

When performing reciprocating movements in the cylinder creates a vacuum, which provides the water supply. It is fed under pressure into the cylinder and is outputted through the spout when opening the valve crossing. Such a pump is used for pumping out dirty water from the shallow depth of sources to 7.5 m.

The peristaltic pump action pump for pumping water is arranged similarly to the piston, with the exception of greater length of the piston and the cylinder, thereby creating a more powerful vacuum, thereby raising the water at a significant depth -. to 28 m is used instead of a pair of rods of rod connected by special hinge.

Hand vane assembly has a long handle, which is equipped with a rotary pump. When performing rotational movements carried fluid suction and passing it through the overflow outlet. To operate such a pump will need a garden hose flexible. The unit is quite compact, so it is easy and convenient to transfer to a new place.

How to choose a sump pump to pump water

There are a few simple guidelines for choosing the drain pump for pumping water out of the basement, well, cellar, swimming pool or other facility. First of all take into account the scope of use. To do this, selected surface or submersible type pump unit. Equally important is the maximum depth of the lowering of the pump unit, which each model has its own. It should also consider the level of fluid cleanliness to be pumped, as each model works with the environment a certain viscosity.

Important! For home use is better to consider the immersion model that can be used regularly at any time of the year.
