API Standard Pump VS1, VS6 – VPCS( KVSL) / VPCH (KVSH)

API Standard Pump VS1, VS6 – VPCS( KVSL) / VPCH (KVSH)

VPCS( KVSL) / VPCH (KVSH) is a VS1/VS6 type process pump. This pump is suitable to be installed at a below-ground level for the desired NPSH. The design ensured optimum performance at critical suction conditions. It is manufactured as per API 610, suitable to align with standard motors. The range covers a pump head of 1000 m. The pump offers a discharge pressure of up to Cl. 600#. The nozzle has the bottom-side and side-side, the direction of rotation is clockwise when viewed from the coupling end. This pump can be offered with an inducer design to reduce the column length for below surface operations.

Max Head:Up to 1000 Max capacity:Up to 45000 m3/hr

  • The pump is designed and manufactured as per API 610 standard.
  • The first stage impeller can be installed at the desired level below ground to ensure sufficient “Available NPSH”. This feature ensures reliable operation under critical suction conditions.
  • Easy inspection and repair maintenance of bearings and mechanical seal after removal of coupling spacer only.
  • Interstage casings and column pipes are flanged and bolted together for easy installation and maintenance.
  • Inducer design for the VPCS( KVSL) / VPCH (KVSH is an optional feature to reduce column length below ground to increase reliability

  • Light hydrocarbon and condensate handling in oil refineries and petrochemical industries.
  • Handling of LPG in loading/unloading applications and in LPG bottling plants.
  • Water condensate handling.
  • Sea Water, Cooling water.
