Page 7: Introduction
This installation, operation, and maintenance manual is designed to help you achieve the best performance and longest life from your Summit Pump. This pump is a positive displacement internal gear type. The pump’s drive shaft turns a ring gear (rotor), with internal teeth, which rotates the external gear (idler). -
