Additel 959A
Additel ADT 959A
Hydraulic Large Volume Ultra High Pressure Calibration Test Pump
- Pressurise large-volume workload
- Generate pressure to 40,000 psi (2,800 bar)
- Increase and decrease pressure smoothly
- Three pressure ports
Additel 959A Hydraulic Pressure Calibration 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 filling large volume workload with the hand pump and providing smooth increase and decrease of pressure with the high pressure, fine adjust screw press. The 959 test pump incorporates an isolation valve which isolates the calibration volume from the check valve associated with the hand pump.
