Pumps vertical multi -stage VM

Condition Electro-axial VMA 3/12-F-M2.2KVT , where
  • ELECOMALARS VM unit - unit electric vertical multi -stage;
  • 3 - pump performance, m3/h;
  • 12 - number of steps;
  • F is the option of connecting the pressure and absorbent pipes: T - oval, f - flange, v - connection "Victaulic", C - flexible connection;
  • 2.2 - engine power, kW ("M" - 220V, without "M" - 380V)

Purpose and scope
The electrical vertical multi -stage unit is designed to increase the pressure and circulation of pure cold and hot water in communal, industrial and agricultural water supply, heating systems, ventilation, air conditioning and hot water supply, washing units and fire extinguishing systems, drainage, irrigation and sprinkling systems.

Design
Multi-stage vertical centrifugal an increase in water pump high pressure with a modular construction in a line of absorption and discharge pipes of the same nominal diameter.

The transmission of the torque from the electric motor to the pump is carried out through a convenient longitudinally - wheel coupling. The head of the pump is simultaneously an intermediate loading part of the drive electric motor, and the lower part with the absorption and discharge pipes form a pump support. Chrominopolist steel is used to manufacture the internal parts of the pump, provides their corrosion stability and high wear resistance.
