VA Serie

Vertical Axial Flow Pumps



Vertical Axial Flow Pumps


The VA series are axial flow Vertical Pumps for large water flows at low and medium heights at water elevations. It is suitable to be driven by solid-shaft electric motor, hollow-shaft electric or diesel through pulleys (flat / grooved) transmission, or gear heads. The impellers are of the propeller type that guarantee the maximum passage of water. 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.

The VA series installations are made up of three parts

  1. Hydraulic body
    • The composition of the hydraulic body is roughly formed by a body of one or two pump bodies and one or two axial impellers. The set of impellers rotates with a central shaft that transmits the power of the engine.
  2. 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 and a separator with a central bearing to join the stages.
  3. Head
    • The outer head is anchored to the bearing plane, discharging the flow from the pump to the pump. outside pipe may be:
      • Above the support plane, allowing for easy maintenance and overhaul. the elements installed in the rising main.
      • Below the plane of support, normally due to overcome the small unevenness.
      • Underneath the work surface, with two flanges (suction/drive) for re-pumping facilities.
