Gear Pump Overhaul Kit for GPI Models

This overhaul kit fits Great Plains Industries gear pumps including the G20, G8P, M-1115, M-150, M-180 and M-240 models. It provides the components needed to restore sealing and internal wear surfaces on compatible units. The kit is identified by part number HAWA 110504-1.

Straightforward bench rebuild with correct parts

Installation requires removing the pump from the system and disassembling the gear housing on a clean work surface. The most common issue is damaging new seals during reassembly if the housing bores are not lubricated or if the gears are forced without proper alignment. Old gasket material left on mating faces will cause leaks.
