The Additel ADT 959A hydraulic ultra-high pressure test pump is a benchtop pressure pump designed to generate pressure to 40,000 psi (2,800 bar). The ADT 959A test pump features a dual-piston system ideal for filling large volume workload with the hand pump and providing smooth increase and decrease of pressure with the high pressure, fine adjust screw press. Three hand-tight quick connectors allow easy connecting to and disconnecting from the test pump.
The ADT 959A incorporates an isolation valve that 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 959A is an ideal comparison test pump for calibrating pressure measuring instruments such as test gauges, indicators or transducers.
