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
