Portable
Lightweight aluminium keeps weight down to 4.5kg.
Safe
Optional factory fitted relief valve prevents over pressurisation.
Range
Six models with ranges from 110 bar to 700 bar are available
High Flow
Interchangeable plungers allows selection of optimum pressure/flow
characteristics.
Accessories

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 500KB and LD4. Please contact our technical department
if in doubt.
Pressure Relief Valve
A factory fitted 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 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
A range of standard tanks to satisfy most requirements is illustrated
in the diagram above. They Hydrapak can easily be fitted
to custom built tanks.
Interchangeable Plungers
High/low pressure plunger kits can be supplied to change the
pressure/flow characteristics to any of the six standards.
