MODEL HPU2 (OH2)

The HPU2 is a two stage, overhung end suction pump for clean liquid and medium flow/high head applications. Higher specific speed due to the two stage design also offer higher efficiency. The HPU2 meets the intent of API 610, 11th Edition and is suitable for a wide range of applications in refinery, petrochemical, gas processing and offshore oil production services.

Standard Features:

  • Two stage design with wide hydraulic coverage.
  • Single seal offers cost savings, especially where expensive flush plans are required.
  • 300# flange ratings, end suction, top discharge design.
  • Available in all API 610, Table H­1 materials.
  • Cast or fabricated impellers, for expanded hydraulic coverage.
  • Close clearance metalized carbon throat bushing for optimal control of stuffing box environment.
  • Rigid shaft design for minimal deflection to meet and exceed API 610 requirements.
  • Cylindrical roller radial bearings for ample load carrying capability.
  • Duplex angular contact 7300 series thrust bearings.
  • Labyrinth bearing housing isolators.
  • Heavy duty baseplate, drip rim or drip pan designs.

Optional Features:

  • High pressure special casing design.
  • Oil Flinger/Oil Ring/Purge Mist/Pure Oil lubrication of bearings.
  • Oversized shafts and bearing housing arrangements.
  • Fan/Heat­sink bearing housing cooling arrangement for operation at elevated temperatures, to eliminate the need for cooling water.
  • Magnetic bearing housing isolators.
  • Pre­-grouted baseplates or non-­grouted baseplates.
  • Non­-standard API 610 material available.
