The OHP screw pump is dependable, economical low-pressure pump with smooth operation. Design is free from pulsations, ensuring long service life and quiet operation. The OHP screw pump can be fitted with a 3 kW -7.5 kW electrical motor.

This screw type rotary pump features axial flow, has only three moving parts and can be installed in any position, including above oil level. The main screw is the only driving part, allowing the secondary screws to move. The secondary screws act as sealing parts and are hydraulically turned by the fluid being pumped. There is only a rolling action between the main screw and the secondary screws. The rolling action eliminates noise and vibrations.

The pumps can be used for:

• presses
• machine tools
• injection moulding machines
• dumping equipment
• elevators
• variable pitch propellers
• hydraulic winches
