Categories: 

Process Equipment Company and ITT PRO Services is pleased to announce t he availability of the PRX-OH2, a back pull-out assembly which provides a complete replacement to an existing API 610 OH2 power end, while using the customer's existing casing, impeller and driver. The more robust design of the PRX-OH2 with stiffer shaft helps improve mean-time between repairs (MTBR) for the pump. In addition, its latest API 682 edition compliant mechanical seal chamber helps reduce emissions. Inventory of the common sizes of the PRX-OH2 are available in Houston, Texas, and help reduce lead time to four weeks.

Description

The PRX-OH2 is a back pull-out assembly which provides a complete replacement to your existing equipment while keeping the existing impeller and casing. The replacement scope consists normally of bearing housing assembly, shaft, seal chamber cover with wear ring, throat bushing, keys and impeller nut. It is available in 4 API seal chamber sizes (#2/4/6/8) and 3 materials classes (S-6/C-6/A-8).
