Description
Description
The ADDITEL 912 pneumatic pump is a manual pressure generator and controller providing a range from -0.95 bar to 4 bar (60 psi). It features a fine adjustment screw that allows pressure trimming down to 0.001 mbar. The pump is built with an isothermal chamber to reduce external temperature influence and ensure pressure stability. The absence of a check valve reduces internal disturbances and lowers maintenance requirements. Two hand-tightenable connectors enable fast connection and disconnection of gauges without PTFE tape or tools. The unit is suitable for low-pressure applications and for on-site or laboratory calibration of transmitters and pressure gauges.
