The Additel 960 Hydraulic Pressure Test Pump is purpose-built to generate ultra-high pressure up to 60,000 psi (4,200 bar). It incorporates a dual-piston system, optimized for fast filling of large-volume workloads via the hand pump, while enabling smooth, precise pressure increase and decrease via the high-pressure fine-adjust screw press.

The 960 test pump features an integrated isolation valve, which separates the calibration volume from the check valve in the hand pump circuit. As check valves are a common source of leaks and maintenance requirements in high-pressure systems, this isolation valve delivers more stable pressure measurements and reduces long-term maintenance needs. The Additel 960 is an ideal comparative test pump for calibrating high-pressure measuring instruments such as precision test gauges, pressure indicators, and high-pressure transmitters.
