Gear Pumps

Product Overview

Gear Pumps are designed primarily for metering and transfer applications. Their modular design allows a wide variation of flow ranges with a standard parts set. Gear Pumps are self-priming and are “constant flow” pumps when RPM and differential pressure are constant. The materials of construction for bodies, gears and seals, provide a wide range of fluid compatibility. For more details, please click the blue "Pump Overview & Data Sheet" button.

A minimum 80 mesh screen is generally recommended for for filtering such things as shavings, packaging materials, etc. in systems that are generally free of particulate contamination. For systems where sand, silt or other particle contamination is expected, a 400 mesh minimum screen is recommended.

To prevent pump starving and cavitation, a sufficient strainer area should be provided. The fluid flow rate and viscosity determine how much strainer area is needed. System design should always include testing with the inlet strainer blocked and with maximum fluid viscosity.
