fluids.

Gear pumps KF are distinguished especially

by their wide range of variants which are assembled

as required on the modular principle and also permit

subsequent upgrade.

The pumps are also suitable for media with low

lubricating properties.

The standard housing sections are of grey cast iron.

The gear units are manufactured from high-strength

case-hardening steel, hardened and mounted in

special multi-compound plain bearing bushes.

The standard drive shaft is sealed by single radial

lip-type seal.

All pump sizes incorporate helical tooth system.

This feature, combined with special gear geometry,

results in extremely low noise levels and reduced

pressure pulsation.

Working Notes

• The fluids should ensure a certain minimum

lubricating properties, should not contain solids and

should be chemically compatible.

• Avoid dry operation.

• The pumps may only be operated in the specified

direction of rotation, as otherwise the shaft seal will

be destroyed.

• In order to prevent excessive overpressure, a safety

valve should be provided in the system or on the

pump.

• The pressure relief valve attached to the pump may

only be used as safety valve for short-term operation.

• A separate pressure relief valve with return line to the

reservoir must be foreseen, if a partial discharge flow

has to be drained over a prolonged period
