Gear for Rotary Gear Pump

The Dayton PPM966102G is a replacement gear designed for use inside compatible rotary gear pumps. It is intended for maintenance technicians and operators who need to restore pumping function after wear or damage to the original component.

Replaces worn or damaged pump gears

This gear fits Grainger part numbers 4KHC8, 4KHE8, 4KHE9 and 4KHG3. The upgrade is worth it when the existing gear shows scoring, tooth wear or excessive backlash that reduces flow rate or pressure. It is not for buyers who need a complete pump assembly or a different gear ratio.

Direct drop-in for listed models

Installation involves opening the pump housing, removing the old gear and seating this unit in its place. No special tools are required beyond standard hand tools for the pump bolts. What usually goes wrong is reusing worn seals or misaligning the gear shaft, which causes premature wear or leakage.
