Working principle

It consists of two meshed gears that rotate in a closely fitted casing.

A drive gear (that is driven by a motor) rotates an idler gear in the opposite direction. When the gears rotate, the liquid, which is trapped in the gear teeth spaces between the housing bore and the outside of the gears, is transferred from the inlet side of the pump to the outlet side.

It is important to note that the pumped liquid moves around the gears and not between the gears. The rotating gears continue to deliver a fresh supply of liquid from the suction (inlet) side of the pump to the discharge (outlet) side of the pump.

Easy maintenance, thanks to simple construction

Constant amount of fluid delivery

for each revolution

Precise flow rate control

by acting on the motor speed

Very silent and high volumetric efficiency

especially at low rotation speed
