The VS-VG series are vertical multicellular centrifugal well pumps. They can be installed where vacuuming conditions are limited or where regulations do not allow negative vacuuming. The pump is supported by sections of column pipes, and shafts with sleeves that connect it to the outside. An external head fulfills the double mission, to discharge the pumped liquid, and to transmit to the pump the power of the motor it supports. Custom fabrication for every application and installation.

Some of its advantages are :

  • Good hydraulic performance, higher yields
  • Its configuration allows to increase/decrease the pressure, adding or eliminating phases.
  • Eliminates priming complications, pump always in charge (submerged)
  • Eliminates problems in aspiration
  • Avoids air intakes
  • No pump-motor alignment problems
  • Less noise pollution
  • Cost reduction, minimum maintenance.
  • No bench needed, reduced installation space
  • Less civil works
  • Longer service life

Vertical Centrifugal Multicellular Pumps

  • The installations of the VS-VG series consist of three parts:

    • Pump body
      • The composition of the pump casing consists of a suction casing, a discharge casing, and stages or phases composed of diffuser casings and closed impellers. The operating pressure can be obtained by incorporating the necessary number of stages thanks to its modular configuration. The impeller assembly rotates with a central shaft that transmits motor power.
    • Hydraulic column
      • The hydraulic column is formed by stages, depending on the depth of the well. These stages are formed by a steel tube, a central shaft (which joins the pump shaft and the head shaft) and a separator with a central bearing to join the stages.
    • Head
      • The outer head is anchored to the support plane. Discharges the flow from the pump to the pipe, at the top is the bearing housing with central shaft, motor bracket, and motor. Depending on the type of drive we can find:
        • Drive by solid-shaft motor
        • Drive by hollow shaft motor
        • Driven by gear head and diesel engine
        • Driven by flat and grooved pulleys
    • Water supply and distribution
    • Overpressure systems
    • Water treatment sewage treatment plants
    • Irrigation and sprinkler installations
    • Fire equipment NFPA-20UL / FM
    • Mines
    • Waterparks
    • Therres refrigeration
    • Chemical industries
    • Central or nuclear thermal stations.
    • Refineries, crude oil pumping and refined products
    • Sanitary and cleaning facilities.
    • Industry in general
