Vertical Submersible Pumps

[SENGUTTUVAN]

The engineering data sheet specifies VS4 type pump for the closed drain vessels in the refinery plant. For one of such pump the capacity is 15 m3 /hr and head 60 metres. Two cases have been furnished . Case one with water and case 2 with Hydrocarbon ( with H2S). One of the vendor has selected VS1 type Pump ( single casing with diffuser and 11 stage pump). What is the selection criteria to decide on upon VS1 / VS2 or VS4?

What are you asking- what is a VS4 type pump?

It is the pump designation for vertically suspended single- casing volute line-shaft driven sump pump as per API 610.

cannot understand your problem - spec calls for VS4 - therfore only single stage is applicable - plenty to choose from - 60 metres head is achievable with 1 stage.
Simply google VS4 pump - plenty of hits.
