Pump housing and gear pump: cast aluminium
Technical Data
• For applications that require high flow rates in the low pressure (LP) range and low flow rates in the high pressure (HP) range
• Presses• Power units for industrial applications such as punching machines and
rescue devices
Applications• Integrated low-pressure unloading valve • Integrated fail safe valve (not suitable for
continuous operation, must not be used to restrict the system pressure!)
• With hollow shaft for direct assembling of motor without bell housing and coupling
Design
• Compact design• Self-venting• Various combinations possible

Calculation of driving motor power
*Pumping elements
p · Vg · n · kP = ηt · 600 · 103
P = Driving power [kW] p = Operating pressure [bar]Vg = theor. displacement [cm3/rev]n = Speed [rpm] ηt = Overall efficiency approx. 0,8
k = Pulsation factor - with 2 pumping elements: k approx. 1,60 - with 3 pumping elements: k approx. 1,05 - with 5 pumping elements: k approx. 1,00
