Pump Series


GHA Series

The GHA Series is designed for continuous duty service for applications in the operating ranges noted. These units are available with head and backhead jackets for temperature control, along with packing or mechanical seal options. This abrasive handling, extreme duty series, provides superior wear resistance. The design also provides superior rotor shaft support and an integral, maintenance-free radial/thrust bearing for reduced deflection and wear. Reduced speeds enable service over extended periods.
