CENTRIFUGAL PUMPS, API 610 0H4-OH5

General

Based on the same hydraulic design as for our OH3 pumps, we may supply the pumps with rigid coupling (OH4) directly coupled to the driver shaft. Another option is a design with close coupled motor with an extended shaft. These pumps do not provide a back pull-out design and the motor do normally need to be removed during maintenance.

Design features

  • Do not meet all API 610 requirements
  • Inline nozzle design alternatively same side
  • Single or double volute depending on size to reduce radial forces
  • Impeller loads transferred to motor bearings
  • Seal area meet API 682
  • Mechanical seals and seal systems as per API682
  • Low flow and high flow design and many other options available
  • All metallurgies available
  • Design to NORSOK and customer specifications available
