Yale PY-04 Compact Electric Motor Pumps

Portable 700 bar | 5 L Reservoir | 230 V 1-Phase | Two-Stage with Remote Pendant

The Yale PY-04 range comprises portable two-stage electric hydraulic motor pumps at 700 bar with 5 litre useable reservoir. Three variants cover single-acting (2/2-way) and double-acting (4/3-way) cylinder applications, plus a solenoid-valve variant for remote control. All variants run on 230 V single-phase supply.

Designed for maintenance and repair jobs

Yale describes the PY-04 as particularly designed for maintenance and repair jobs. The combination of manually-operated valve and remote pendant control provides operator freedom of motion and ensures safe holding of the load. The 1.5 m remote pendant control is used to start the motor even under full load. Yale specifies manual valve function: advance / stop / return.

Suitable Applications

Per Yale: maintenance and repair work. PY-04/2/5/2 M (2/2-way manual) for single-acting cylinders; PY-04/2/5/4 M (4/3-way manual) for double-acting; PY-04/2/5/2 E (2/2-way solenoid) for remote-controlled single-acting.

Key Features

  • Light-Weight Portable Design: convenient carrying handle.
  • Two-Stage Powerful Pump: rapid no-load travel; high-force loaded operation.
  • 0.37 kW 230 V Single-Phase Motor: standard mains supply.
  • Remote Pendant Control 1.5 m: starts motor even under full load.
  • Manual or Solenoid Valve Options: matched to application.
  • Thermal Overload Protection: built into motor.
  • Supplied with Hydraulic Oil: ready to use.
  • IP 50 Motor Protection: Yale-specified ingress protection.

Frequently Asked Questions

Q: How does the PY-04/2/5/2 M differ from the PY-04/2/5/4 M?

Yale specifies the 2/2-way manual valve (PY-04/2/5/2 M) for single-acting cylinders. After motor stop, the valve gives two options: cylinder holds pressure, OR cylinder automatically retracts. The 4/3-way (PY-04/2/5/4 M) controls double-acting cylinders with explicit advance/stop/retract positions.

Q: How does the solenoid variant work?

Yale documents: push button 1 starts the motor and cylinder advances; in neutral the pressure is held; push button 2 activates the solenoid valve, releasing pressure and retracting the cylinder.

Q: Is the pump supplied with oil?

Yes. Yale specifies the pump is supplied with hydraulic oil.
