MSD Axially Split Multistage Pump

The MSD pump has the broadest hydraulic coverage of any BB3 type multistage pump in the market. There are over 10 000 MSD pumps installed in product pipelines, boiler feed, water injection and even nuclear safety-related services around the globe.


Main benefits

  • 600#, 900# and 1500# flange ratings to suit project requirements
  • Axially split casing means rotor balance is not disturbed when rotor is installed

  • Opposed impellers balance axial thrust, saving lube system costs on most applications

  • Double suction, first-stage available on most sizes for reduced Net Positive Suction Head (NPSH)

  • Industry-leading hydraulic coverage means efficient performance

Main applications

  • Refined product pipeline

  • LPG pipeline and CO2 injection
