In fact, many Hydrapaks are not used! They are kept as a back-up system as an alternative pumping method for when power packs or power sources fail.

	Fast – two-speed operation - 110 bar low pressure up to 700 bar high pressure.
	High Flow – interchangeable stainless steel plungers ranging from 110 – 700 bar.
	Versatile – can be used in many applications and perfect when precise fluid displacement is required e.g. pressure testing and lifting cylinders.
	Portable & Compact – lightweight aluminium keeps weight down to 4.5kg.
	Non-Corrosive – can be used with water, Skydrol (aircraft fuel), oil and other fluids.
	Accessories – double acting valves, different tanks sizes, mounting frames, pressure gauges and fixing kits are available.

*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.

*NOTE: Not suitable for use in water.

Tanks
A range of standard tanks to satisfy most requirements are illustrated in Fig Y. The 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.
