BASIC DESCRIPTION
Q und QLS line pumps are particularly designed to be used in mobile hydraulic systems of agricultural and road
building machines as well as in advanced hydraulic systems of material handling devices. The geometric volume size
range of this line is Vg = 10 to 100 cm3/rev.
The pumps are characterized by simple construction with a hydraulic pressure balance, compact dimensions and a
wide range of types and connections. The flange and the pump cover are made of grey cast iron, the body of a section
bar made of a heavy duty aluminum alloy. The gear wheels with 12 teeth made of heavy duty steel are optimized for
low-noise applications. QLS construction enables the pumps to be used at low revolutions at high pressure.
Q and QLS pumps are produced in various designs with diverse drives, connecting flanges, fluid inlets and outlets.
They comply with the ISO, SAE, UNI as well as other worldwide standards. They can be delivered in one-way or
multiple designs. Furthermore, the pumps are also available in reversible version with internal or external drainage.
