Hydraulic piston pump ADT 959

manualaluminumcopper

Overview
The ADDITEL 959 manual hydraulic pump generates and controls pressure up to 2800 bar (40,000 psi). It features a dual-piston system for filling large-volume systems under pressure (420 ml reservoir) while providing fine pressure adjustment both increasing and decreasing. An isolation valve protects the calibration volume to minimise leakage and stabilise generated pressure. Three quick-release, hand-tight connectors enable fast instrument connections without tools or sealing tape. The 959 is intended for calibration of gauges and transmitters in a laboratory environment.
