Flowserve HPX Pump Bearing Housing

Published on: 

Redesigned API 610 and API 682-compliant process pump

Flowserve redesigned the bearing housing of the HPX centerline-mounted process pump. The new inner slinger optimizes bearing lubrication; a finned upper bearing housing surface improves heat dispersion. The ample oil sump extends maintenance intervals and improves cooling capability while simplified oil collectors ensure adequate oil flow. A top-side oil passage has been optimized to further improve heat dispersion. It’s API 610 (OH2) and API 682 compliant, and also is interchangeable with existing pumps.


The HPX pump is ideal for oil and gas, biofuels, chemicals, petrochemicals, boiler circulation, reverse osmosis (RO) desalination, solar, and water. Better bearing lubrication and heat dispersion enables the HPX pump to withstand higher process and bearing temperatures. The HPX pump extends mean time between repair (MTBR), provides ample sump volume, eliminates water cooling, and minimizes maintenance due to a simplified skid design.
