Internal gear pump
Type QPH 3
with constant displacement volume
Characteristics
The new series QPH were developed particularly for the high requirements of industrial
hydraulics. Their favourable noise characteristic, extremely low delivery and pressure
pulsation, outstanding efficiency within broad revolution and viscosity ranges, have firmly
established gap- compensated high pressure internal gear pumps among high pressure
pumps. Simple combinability to multiple pumps with separate or common inlet is given.
The QPH... is a consistent advancement that already for over 40 years in the industry used
gap-compensated internal gear pump technology.
