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


Flow Rates: Range to 2 liters/min.

Max. Pressure: 30 psi.

Max. Fluid Temperature: Range to 180°F (82°C).

Motors: Thermally protected, continuous duty rated. Available in brush and brushless type DC motors.
