Hydraulic Ultra-high Pressure Test Pump
Additel 959A
OVERVIEW
The new Additel 959A Hydraulic Pressure Test Pump is a benchtop pressure pump designed to generate pressure to
40,000 psi (2,800 bar). This pump incorporates a dual-piston system which is ideal for lling large volume workload
with the hand pump and providing smooth increase and decrease of pressure with the high pressure, fine adjust
screw press. The 959A test pump incorporates an isolation valve which isolates the calibration volume from the check
valve associated with the hand pump. Because the check valve can often be a source of leaks and maintenance,
the isolation valve provides more stable measurements and reduces potential maintenance of the pump. The Additel
959A is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators
or transducers.
