Presentation
The pneumatic pump ADT 920 ADDITEL is a manual calibration pump designed to generate and control pressure up to 200 bar (3000 psi). A fine-adjustment screw enables pressure setting down to 0.1 mbar. The pump uses a shut-off valve to ensure high stability and reduced maintenance. It includes a liquid isolation chamber with drain to purge traces of liquids from the air. Two hand-tight connections allow connection and disconnection of gauges without PTFE tape or wrenches. It is suitable for high-pressure pneumatic applications and for calibrating transmitters and pressure gauges in the field or in the laboratory.
