This pump provides remote control of a double acting cylinder, by the use of a
solenoid operated direction control valve providing instant operation and a fast response.
At the middle position, port P is locked and ABT connection is used.
Example of Use: To remotely control the operation of a double-acting cylinder.
Connect the high pressure hose and cylinder as shown ‒ specifically connect port A
to the push side and port B o the pull side.
1) Open the air valve.
2) Before operation, set the pressure switch to the required pressure.
3) Push the “Push” button of the operation switch. The motor starts and hydraulic oil
is discharged from port B, the cylinder piston advances, system pressure rises
allowing a specific operation to be performed.
4) When pressure reaches the level set on the pressure switch, the motor will stop
and pressure and cylinder stroke position will be maintained only as long as the
“push” button is activated (pushed).If the “Push” button on the operational switch
is released, pressure falls.
5) When the “Pull” button of the operation switch is pushed, the pump motor will
start, discharging hydraulic oil through port B and causing the cylinder plunger
to retract.
6) When operation is complete, retract the plunger of the double acting cylinder.
7) Close the air valve.
