HYDRAPAK

Hydrapak

No Power Source? – The Hydrapak pump is the ideal solution when your environment means that no power source is available or when your power source fails.

Hydrapaks are currently in use throughout the world and many of our Hydrapaks are kept as a back-up system as an alternative pumping method for when power packs or power sources fail.

The Hydrapak pumps have the following characteristics:

• Fast: two speeds operation gives rapid prefill or no load approach
• Compact: small in size but produces up to 700 bar pressure
• Portable: lightweight aluminium keeps weight down to 4.5kg
• Safe: optional factory fitted relief valve prevents over pressurisation
• Range: six models ranging from 110 bar to 700 bar are available
• High Flow: Interchangeable plungers allows selection of optimum pressure/flow characteristics.

 

Fluid Compatibility

The standard pump is supplied with nitrile rubber seals suitable for use with mineral oils, water, oil/water emulsions, paraffin and glycerine. The pump body should not be left in contact with water for prolonged periods. After using salt water in the pump, thoroughly flush clean.

Ethylene Propylene (E.P) seals are available to order for applications using phosphate ester based hydraulic fluids and vegetable based brake fluid. E.P seals are compatible with skydrol 500B and LD4. please contact our technical department if in doubt.

 

Pressure Relief Valve

A factory set pressure relief valve may be fitted to the pump and set at any specified pressure between 56 and 700 bar. We strongly recommend that all hydrapaks are fitted with a pressure relief valve to prevent overloading and exceeding maximum safe working pressures.

 

Gauges

100mm gauges and a fixing kit are available for horizontal mounting of a pressure gauge above the top face of the pump. For pumps with a double acting valve a fixing kit for vertical mounting is supplied. Six standard gauges corresponding to the six standard pressure ratings are available.

 

Double Acting Valve

A three position four port valve for control of double acting cylinders is offered as a factory fitted option. Valve outlets are tapped 3/8 NPT. There is no release valve assembly fitted to the pump body and, although internal leakage of the valve is minimal, isolation valves should be fitted to circuits where pressure must be sustained

Tanks

Tanks are available with all Hydrapak pumps. The tanks are of aluminium construction.

A range of standard tanks to satisfy most requirements are listed in the table below.

The Hydrapak can also be fitted to custom built tanks.

Larger tanks are available upon request.

Frames and skids are available upon request.
