The pump VA is a circulation pulser for systems of heating and conditioning with the small extent of pipes. Is suitable for installation in private houses, small commercial and public buildings. The pump performs function of compulsory circulation of water, maintains the stable temperature and pressure in system, allows to regulate intensity of heating or cooling indoors.
- Pressure of a water column: to 6 m;
- Working range: expense from 0,5 to 3,6 m ³ / h;
- Max. working pressure: 10 bars (1000 kPa);
- Water temperature: from -10 °C to +110 °C;
- The pumped-over liquid: pure, without firm inclusions and mineral oils, not viscous, chemically neutral;
- Max. content of glycol: no more than 30%;
- Engine type: bipolar with a wet rotor. Three speeds of rotation;
- Food: 1 x 230 V ~, 50 Hz;
- Diameter of branch pipes: 40 mm;
- Assembly length: 130 and 180 mm;
- Type of connection with the pipeline: carving;
- Class of protection of IP: 44;
- Cable input: PG 11
- Installation: an engine shaft in horizontal position.
The case of the pump block is made of cast iron, since October, 2017 for protection against corrosion is painted with a special kataforezny covering. The electric motor case from high-strength cast under pressure of aluminum. The driving wheel – a tekhnopolimer. The rotor shaft from the tempered stainless steel, since October, 2017 is delivered in new modification with a ceramic shaft, is established on the graphite plugs greased and cooled by the pumped-over liquid. A rotor casing, a sleeve of the stator and a flange of hydraulics from stainless steel. The persistent bearing – ceramics, sealing rings – EPDM, an air descent stopper – brass.
Feature of the pumps DAB is that their bearings are constantly greased and cooled with liquid which circulates in system. Thus, durable and trouble-free functioning is ensured. The bipolar asynchronous electric motor of the pump has the built-in protection against an overload. An energy efficiency index In or With, depending on model.
- It is easy to rectify a number of faults thanks to convenient system of analysis of the pump – for removal of the case it is required to turn off only 4 screws.
- It is comfortable to use the pump thanks to the low noise level created during the work. Noise level is comparable with a quiet conversation of the people standing nearby.
- Will serve most long thanks to the reliable design of the pump checked by time and qualitative materials.
- It is easy to adjust the pump under requirements of system thanks to a possibility of switching of speed of rotation of the engine.
- Simple and bystry installation as for installation quick disconnect connections are used.
- Installation in any place - both on giving, and on the return lines of the pipeline because the pump can work with temperature to + 110C.
