Shaft, Turbine Type VAB

Vertical shaft, turbine type centrifugal fire pumps have submerged impellers contained in a series-bowl assembly at the bottom of a vertical shaft. The design is similar to pumps used extensively for industrial and municipal service. 

These pumps are FM Approved for discharging water from lakes, streams, open sumps, drilled wells and other equivalent subsurface sources. Each pump consists of a discharge head, motor stand, column pipe, line shaft, bowl assembly and suction strainer. 

For electric drive, FM Approved pumps must be used with a vertical, electric motor. For internal-combustion-engine drive, FM Approved pumps must be connected to the FM Approved engine through an FM Approved right-angle gear drive.

Sea Water

Sea Water is being widely used for various applications including Intake & Cooling, which are the major ones. Sea Water Pumping is prevalent in most of the industries out of which Power Plants / Desalination Plants, Chemical Plants are major users. Other plants like Steel Plant, Paper Mill, Cement Plant, Mines are also using sea water extensively which have necessitated complete relook at the selection of appropriate materials for pump. We are one of the the pioneers in sea water handling pumps to combat various types of corrosion as under :

  • Galvanic Corrosion of Metals in Sea Water

  • Microbial Corrosion or Microbiologically-influenced Corrosion – caused by the presence and activities of microbes

  • Pitting Corrosion – WPIL’s experienced engineering team
    developed various methods to combat such corrosion
    by:

    • Proper selection of materials extending from Stainless Steel 316 grade
      to Super Duplex Stainless Steel (SAF 2507 or UNS S32760) i.e., PREN numbers upto 44-45 or Nickel Aluminum Bronze or D2 Ni-resist/various other higher grades of stainless steel depending on the degree of corrosiveness which depends on the geographical area as well.

    • Providing Cathodic protection by an electrical means of corrosion control, the above selection of materials not only helps the pumps to run trouble free in Sea Water handling applications but also in media having other corrosive waters as well. All these led to huge response from clients worldwide.
