Pump for heating: circulating, DAV design

pump is used for heating in order to heat the system to work most effectively to heating system worked most efficiently, it is necessary to use a circulating pump for the heating, whereby the heat carrier occurs by wrapping pipes, and is carried out the temperature increase in the room. Pump operation, in which the coolant will either move quickly or slowly, creating an uneven heating, will not bring the desired result, so it is necessary and able to choose the correct instrument.

Tips for choosing the circulation pumps for heating

Through the purchase of the pump, it is not necessary to rely on the kind of fuel used boiler itself, it does not matter. On the market there are 2 types of pumps - with a wet and dry rotor. Before you decide on a particular model, you need to consider a number of factors.

Namely:

1. The size of the heated space - the more the heating area, the more powerful and better to be pump.
2. What will be the most comfortable temperature in the room - the rate of heating depends on the performance factor.
3. Number of floors in the house - to cope with this work, you need to purchase a powerful pump from a manufacturer with a good reputation, otherwise the money will be wasted.
4. Functions and type of boiler for heating - for modern models it is necessary to use also new pumps, otherwise the technology of operation will not be suitable either to one or the other.

choosing a circulation pump for heating should consider the size of the heated space

impact and the pressure in the pipes themselves and the desired exit temperature - with possible problems with the parameters, the presence of narrow pipes capable of handling only the device with good power, Quickly driving the coolant and creating the necessary temperature. Also, the pump itself can be installed in two ways - either built-in directly to the boiler itself, or as a completely separate element, welded into the heating system. The first option is used in most modern models, and the second one - in rooms with an old heating boiler.

Circulation pump DAV: characteristic

The characteristics of the pumps are special. Pump with wet rotor - in it the impeller and the rotor are located in the coolant, thus ensuring a uniform cooling of the motor. All its elements are made of high-quality materials, so they do not lend themselves to corrosion. But, in addition to good quality, they still have a significant drawback - low efficiency. There are also other advantages - a small noise level, an affordable price category, there is no need for a constant technical inspection.

Similar devices are used in small houses, then their power is enough to warm up.

Pump with dry rotor - in such a device in the coolant only the impeller is located, and the rotor is separated with good sealed gaskets from liquid ingress. The advantage of such a purchase is its ability to work in large rooms.

DAV circulation pump works well on slopes and narrowed areas

Circulating pumps have certain advantages:

• can rapidly heat the system at startup, because of this, faster warm up any room;
• Has a fairly high performance factor;
• Works well even on slopes and narrowed sections.

The disadvantages are the high noise level and the need for servicing, since grease is quickly erased in the device. DAV is an Italian company, and has established itself as a reliable manufacturer whose products differ not only in durability but also in an affordable price category.

Types of pumps for heating

The durability and high quality of such instruments allows them to be used even in large-sized buildings and industrial organizations. The company DAV represents several varieties of pumps.

• Universal - they are mainly used in administrative and industrial buildings;
• Units made with the presence of a bronze body, which has an increased level of resistance to corrosion;
• Also available is an affordable series for use in residential buildings and apartments;
• Pumps with increased hydraulic characteristics, for use in large facilities;
• Industrial equipment with a regulator.

There are also devices with a dual circulation system, with the presence of a backup pump, used in systems with increased levels of complexity and responsibility. The company Dove guarantees excellent performance and long-lasting work without failures for many years, fully paying for the money spent on the acquisition.

Standard design of the circulation pump

The design of the pump has such components as the body, most often made of strong materials, characterized by an increased level of corrosion resistance - steel, cast iron, bronze, brass. The electric motor drives the rotor and starts the operation of the equipment. The rotor can produce both ceramic and steel, and the shaft also has an impeller. Most often, almost all models have such a design, differences can only be found in specialized products intended for a particular job.

The specialists give a number of recommendations that will help with the installation of the pump:

1. The bypass is necessary; this is necessary in order that after a casual breakdown, the system continues to function.
2. The expansion tank must be installed 1 m higher than the highest point in the heating system. This will increase the efficiency of the entire system as a whole.
3. It is also necessary to install Mayevsky cranes so that in the event of excessive air accumulation in the system, air can be easily vented.

Design of the circulation pump

Buying the circulation pump, you can get the advantages - to increase the efficiency and speed of heating the rooms in the house in all weathers, to maintain a comfortable and cozy atmosphere indoors, even in a cool and damp, save moneyOn payment for electricity, because the pump runs sparingly, and allows you to reach the desired air temperature much faster without using heaters.

Before buying such an important unit, you need to inspect all the devices offered, find out their characteristics, ask about the price category of each, learn about the availability of a quality certificate and a guarantee.

All these subtleties will allow you to purchase a quality product, it will last for many years, filling the house with warmth and coziness. The most well-proven European manufacturers, they have excellent reviews of many consumers, both for use in living quarters, and in offices, factories and large construction sites. These firms value their reputation and create units that meet the required standards, capable of working for many years without failures and breakdowns. And in case of any problem, you could quickly repair or purchase the necessary parts.
