OHVL vertical low flow high head pump

Aim high with our long-life solutions

The OHVL is our API 610 (ISO 13709) Type OH3 low-flow inline overhung process pump. It covers the low-flow end of the OHV range map. The unique low-flow impeller design provides gap-free coverage for low-flow, high-head applications. The bearing frame and mechanical seals from OHV are utilized to minimize spares inventory.
