Victor internal geared R gear pumps are self-priming positive displacement pumps suitable for liquids of any viscosity and temperature, which can be corrosive, abrasive and hazardous to the environment. These pumps give a non-pulsating constant flow, so no vibrations on fittings, valves or couplings. Full performance is possible in both directions of rotation. The entire series can be equipped with heating jackets and with connections at 90 ° or 180 °.


Operation principle ;



A: Two gears generate the flow: the rotor (1) and the idler; the internal gear (2).

The rotor moves the internal idler.

B: As the gears are rotating, fluid is drawn into the spaces created between the gears and smoothly 

moved to the discharge port, where the divider (3), called crescent, closes off the free space 

between the two gears.

C: When the gears mesh, the liquid is slowly forced out of the pump.

The result is a constant, even flow without pulsations.

Why u would
choose this product

Selfpriming and non pulsating

This positive displacement pump is self-priming and has a non-pulsating constant flow, so no vibrations in fittings, valves or coupling.

Performance in both rotation directions

Full performance is available in either direction of rotation.

Shaft seal or magnetic coupling

Because the R pump can be supplied with a stuffing box packing, single (cartridge) mechanical seal or magnetically coupled, the applicability of this pump is very wide.
