The Additel ADT 949 High Pressure Pump is a hand operated hydraulic pressure pump designed to generate pressure up to 40,000 psi (2800 bar). With the patented screw press technology, high pressures can be easily generated, increased and decreased smoothly. A specially designed shut-off valve makes the pressure as stable as possible during calibration. Without non-returning valve that is usually used on troublesome hand pump, the ADT 949 requires minimal maintenance. The ADT 949 is an ideal comparison test pump for calibrating ultra-high pressure measuring instruments such as test gauges, indicators or transducers in the laboratory.
