PSP 2 Speed Hydraulic Hand Pump Pressure Test Set.
This test set comprises our PSP two speed hydraulic hand pump mounted on a 15 litre portable anodised marine grade aluminium alloy reservoir with skid. British designed and manufactured, it offers long service life and is compatible with a wide range of media including water and oil. Widely used in portable hydrostatic leak testing of systems, it is easily connected via a flexible hose. The unit weighs just 10.3kg (empty) and is readily moved around site using the integral carrying handle.
Two speed operation allows rapid prefill, controllable changeover between low and high pressure modes and reliable operation up to maximum pressure. A detachable two-position operating handle facilitates pumping action; initial operation in low pressure mode gives a displacement of 51cc per stroke. When the hand load increases, the changeover button can be depressed and the pump switches to high pressure mode – pumping then continues to desired pressure.
There are 6 models available to suit different maximum pressure requirements- high pressure pump displacement varies accordingly (see spec. below). A soft-seal check valve in the outlet ensures positive pressure sealing. Included as standard is a pressure hold-release valve to vent pressurised fluid back to tank and an adjustable pressure relief valve to limit maximum pumping pressure. Seals and valve seats are user serviceable.
An optional direct banjo-mounted 100mm industrial pressure gauge is available, range to suit application. Hose and adaptor sets are also available as accessories.
The test set is suitable for both indoor and outdoor use. Fill the reservoir, connect the hose to your system and the unit is ready to go!
