Pumps SPD 2 VM and SPD 3 VM

Condition
SPD 2 VM 3-30 , where:
  • SPD - Station of increasing pressure;
  • 2 - number of pumps;
  • VM - multi -stage vertical pump;
  • 3-nominal performance in M ​​ 3 /h;
  • 30 - nominal pressure in m.
Pumping stations of pressure increase SPD 2 VM and SPD 3 VM are designed to automatically maintain and increase the necessary pressure in water supply systems and water fire extinguishing, consisting of two or three vertical pumps. They are used as stations of the third lift in residential buildings and microdistricts. The pumped liquid is water, as well as other liquids similar to water in viscosity, density and chemical activity, not containing mineral oils, abrasive and fibrous inclusions. At the request of the customer, pumping stations can be equipped with four pumps.

Advantages of pumping pressure stations

  • Provide the coordinated operation of the pump and system, depending on changes in water consumption (night, nominal, peak regime) and make it possible to adjust the consumption and maintain constant pressure;
  • It allows you to significantly reduce electricity costs;
  • increase the level of comfort to consumers;

Device
The pumping pressure station consists of vertical multi -stage VM pumps, mounted parallel to the common frame and connected by absorption and pressure collectors, control cabinets, pressure tank, locking reinforcement, pressure sensors, manometers and dry relay. The pumping station is delivered in a finished state to connect and work.
Each model of the pressure pumping station operates in a certain range of productivity in tuned constant pressure. This provides maximum comfort to consumers at any time of the day - regardless of fluctuations in the flow rate.
