G Series Sealed Internal Gear Pumps are extremely reliable, durable and cost effective for challenging industrial applications involving both thin and viscous liquids. Find a G-Series Distributor.
The G Series pumps are offered in a variety of connection sizes, materials and flow rates. To simplify installation upgrades, G Series pumps are directly interchangeable with up to 95% of the internal gear pumps currently available on the market including Viking®, Gorman-Rupp® and Tuthill®. No changes needed to piping, driver, coupling, flow rates or baseplates.
EnviroGear Selection Tool
EnviroGear Select is the pump selection application for EnviroGear E Series and G Series Internal Gear Pumps. EnviroGear Select will find all the models that meet a specific set of application requirements or a user can jump directly to a particular model and view a pump’s capability. Select has a built in library of fluids and allows users to add their own fluid products. All selections can be saved under a project and sent to PSG Dover for quotation.

How It Works
G Series Sealed Internal Gear Pumps are designed with only two moving parts and operate equally well in both directions while providing positive, non-pulsating flow. The pump casing revolves allowing for multiple inlet and outlet positioning. A single adjustment end-clearance and an enlarged bearing housing at the rear end of the pump provide easy drive-end access to the shaft seal and single-point end-clearance adjustment for ease of maintenance and adjustability. The G Series pump baseplate systems minimize deflection and vibration to maximize life of the pump, motor and gear reducer. In addition, their innovative design allows easy and accurate shaft alignment.
