Additel 914 / 916 Test Pumps

The Additel 914A and Additel 916 are hand-operated pneumatic test pumps designed as pressure sources for calibrating pressure instruments. These pumps can provide pressures from 95% vacuum to 25 bar (Additel 914A) or 40 bar (Additel 916). Fine pressure adjustments, with a resolution of up to 0.1 mbar can be made with the precision screw press.

Both the 914A and 916 are designed to easily connect to test instruments and have specially designed shut-off valves to provide stable pressures during calibration. Built-in isolators protect the pumps from dirt and moisture, reducing the need for maintenance.
