OHHL low flow high head pumps
Finely tuned pumps for all your industrial needs
The OHHL is our API 610 (ISO 13709) Type OH2 low-flow horizontal overhung process pump. It covers the low-flow end of the OHH 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 OHH are utilized to minimize spares inventory.
