Die Clamping Technology

ROEMHELD D8.819 Screw Pump suited as a pressure source for very small clamping fixtures

• Maximum operating pressure 500 bar
• Piston Ø: 25 mm
• Stroke: 43 mm
• Displacement: 21 cm³
• Displacement/revolution 0.98 cm³
• Torque: 0 - 50 Nm
• Mounting position: horizontal

The screw pump is especially suited as a pressure source for very small clamping fixtures, which must be independent of an external pressure source.

ROEMHELD D8.0115 Hydraulic Power Units, ready for connection and energy-saving intermittent cycling

• Flow rate: 0.82 .. 3.51 l/min
• Operating pressure: 160/250/500 bar
• Reservoir volume: approx. 5 l
• Usable oil volume: approx. 3.2 l
• Continuous duty: up to 120 s
• Motor rating: 0.75 .. 1.1 kW
• Motor voltage: 400 VAC 50 Hz

A special feature is the mounting of pump and electric motor in the reservoir. Thus hydraulic and electric control can be arranged in a space saving way and easily accessible on the reservoir cover. The modular design enables a multitude of control variants. The radial piston pump is available with three different flow rates and operating pressures. To allow an energy-saving intermittent cycling only leakage-free poppet valves are used.
