Description
A compact power unit cannot carry a heavy pump on the motor flange. The PR4-3X/20,00-500RA12V12 weighs 12.71 kg and still supplies 26.5 l/min at 500 bar maximum operating pressure.
Benefits
- 12.71 kg with 4-hole fastening and 63 mm centering.
- 26.5 l/min from 20 cm³ displacement, constant delivery in the open circuit.
- 500 bar maximum operating pressure, radial piston design with 10 pistons.
- FKM seals for HLP hydraulic fluid, cast iron housing.
- Connection diagram 10, cylindrical shaft 25 mm with fitting key to ISO 3019-2, clockwise rotation.
Applications
The pump is used in compact high pressure units, for example on clamping tables, mobile test equipment and joining fixtures. Constant delivery keeps the layout simple, because flow and drive speed are firmly linked. Centering, shaft form and direction of rotation govern the mounting.
