Single Stage Pumps
OHM Overhung Single Stage Pumps with magnetic coupling
OHM
The OHM overhung API 610/API 685 process pump includes the latest in sealless pump technology. It is a horizontal, single-stage, radially split, centerline mounted pump with a high-efficiency magnetic coupling. It is a hermetically sealed system, including a secondary containment with a dry running safety seal.
