RPH-V

Summary

Product identification

KSB RPH-V – Vertical, Single-stage, Heavy-duty Single-casing Sump Pump Type VS4 to API 610 / ISO 13709.

Applications

• Chemical industry
• Petrochemical industry
• Refineries
• Offshore platforms

Design features

• Integral thrust bearings: Oil-lubricated bearings integrated in the pump exceed API 610 life requirements, reducing maintenance. Bearings at the motor are not subjected to thrust forces. Grease lubrication available on request.
• Rigid coupling: Coupling with removable spacer between seal chamber and thrust bearing facilitates maintenance and mechanical seal removal.
• Variety of seals: Seal chamber designed to API 610 allows installation of any API 682 seal. Gland packing available on request.
• Robust radial bearings: Product-lubricated PEEK/carbon guide bearings with bearing span below API 610 requirements ensure low vibrations and reliable operation. Other guide bearing materials available on request.
• Optimal lubrication: Different options for guide bearing lubrication are available:
  • Lubrication by fluid handled
  • Injection of external fluid
  • External grease supply
• Flexible installation: Circular or rectangular sole plate allows easy adaptation to different installation conditions.
