HYDRAULIC POWER UNITS PO4

HYDRAULIC POWER UNITS PO4

MOBILE POWER FOR SMALL AND MEDIUM-SIZED CYLINDERS.
With the compact motor pumps from the PO 4 series, you will be well-equipped if you frequently need to operate small and medium-sized cylinders at different locations. These compact power packs can be relied on to work even for longer periods of time.
Facts:
Portable and particularly suitable for mobile use
Long service life and little maintenance required
Equipped with the special LUKAS radial piston pump with patented suction valves for maximum efficiency
High switchover pressure for fast lifting without load
Constant high pressure flow capacity up to maximum pressure
Power units with remote control allow the motor to be switched on and off in push-button operation. The controls are ergonomically designed. The cable is 3 m long.
Functions of the valve variants
Version NA for single-acting cylinders:
Extend – hold load with motor switched off – retract with motor switched on or off (pressureless oil flow).
Version N3 for single-acting cylinders:
Precision lifting and positioning of the load – hold load with motor switched on (pressureless oil flow) – retract with motor switched on or off
Version N4 for double-acting cylinders:
Extend – hold load with motor switched on (pressureless oil flow) – retract with motor switched on.
Versions with solenoid valve and remote control
L 2/2 – without load-holding function
Motor start-up when remote control is activated, solenoid valve closes. The connected hydraulic cylinder extends as long as the push-button is held down. To retract, release the button, motor stops, solenoid valve in neutral gear, cylinder retracts with spring return.
G 2/2 with load-holding function
Remote control with 3 setting switch
Setting “1” = motor on, solenoid valve closed, cylinder extends
Middle setting “0” = motor off, solenoid valve closed, load is held
Setting “2” = motor off, solenoid valve in neutral gear, cylinder retracts with spring return
