Description
Clamping, pressing and testing duties need high pressure at a manageable flow, and that is exactly what the PR4-3X/20,00-500RA01V08 radial piston pump is built for. It works up to 500 bar operating pressure, delivers a constant flow of up to 26.5 l/min and spreads the displacement across ten pistons in a cast iron housing.
Benefits
- 500 bar operating pressure, dimensioned for high pressure clamping and pressing duties
- Constant displacement of 20 cm3 per revolution, flow up to 26.5 l/min
- Ten pistons, which spread the pulsation across many small delivery strokes
- Cast iron housing and FKM seals for the open circuit with HLP hydraulic fluid
- Cylindrical shaft 25 mm diameter with fitting key to ISO 3019-2, clockwise rotation
- 4-hole mounting flange with 63 mm spigot, pump mass 16.4 kg
Application
The pump feeds clamping fixtures in machine tool building, high pressure test rigs and power units for riveting tools and press fits. Since it is built without a through drive, it is fitted to the motor as a single pump rather than cascaded in a pump stack.
