The Additel ADT 959A is constructed to produce pressure to 40,000 PSIG (2,800 bar), the benchtop pressure pump is equipped with a dual-piston system. The dual-piston system is perfect for filling large volume workload with the hand pump and delivering an even increase and decrease of pressure with the high pressure, find adjust screw press.
As check valves are often the basis of leaks and maintenance, the ADT 959A encompasses an isolation valve. The isolation valve works by isolating the calibration volume from the check valve associated with the hand pump. As a result, measurements are more stable and the incidence of leaks and need for overall maintenance is greatly reduced. The ADT 959A Pressure Test Pump from Additel is an essential asset for any application involving the calibration of pressure measuring instruments.
