With pressure limiting valve and
electronic pressure switches,
Compact, plug-in energy-saving pump unit, ready for electric and hydraulic operation. Complete with: pressure limiting valve and pressure switch, solenoid valve, pressure gauge, float switch with temperature monitoring, oil fill, electrical control with main switch, indicator lamps and flange sockets. Electrical connection, complete with CEKON connector, pressure filter with filter mesh of 25μm. Oil supply via threaded port.
This pump unit is used predominantly as a drive and control element for single and double-acting clamping fixtures.
For connection of 1-circuit control console no. 6906B-2-1 order no. 324723
The radial piston pump is driven via an alternating current standard motor with the energy efficiency class IE3. The motor is protected against overload by a motor protection switch and a thermoelement. The pressure is set via a pressure limiting valve (PLV) and centralised electronic pressure switch (EPS). The pressure is set via the electronic pressure switch (EPS) in the A and B channel. They sit directly in the directional control valve. These EPS control the directional control valve in the working or zero position and output signals for switching the pump motor on and off.
- Reduced power consumption and lower temperature rise
- No heat influence on the oil column in the distributors and loads
- No hazard to components due to excessive rise in pressure
- No risk of injury from hand contact
- No drop in magnetic force
- Prolonged service life of the magnets
The pump unit works in intermittent mode. If pressure drops in the A- or B-channel, the pump is automatically switched on afterward by the electronic pressure switch EDS. In case of low oil level or an increase in oil temperature, the built-in floating switch with temperature monitoring switches the pump off and the fault lamp on the electrical controller comes on.
Ensure correct bleeding when connecting elements. In the event of a loss of pressure, subsequent pumping must not exceed a maximum of 2 times per minute. The pump unit must not run continuously.
Two, three and four clamping circuits on request.
