Additel 925 / 927 Test Pumps

The Additel 925 and Additel 927 are hand-operated, hydraulic test pumps designed as a pressure source for calibrating pressure instruments including gauges, indicators and transducers in the field or laboratory. These pumps can provide pressures from 85% vacuum to 400bar Additel 925) or 700 bar (Additel 927). Pressures can be easily generated and smoothly adjusted because of Additel’s patented screw press technology.

By removing the check valve, Additel has made the 925 and 927 nearly maintenance-free while also solving the leakage problems common in hand pumps. Two hand-tight quick connectors installed on the pump allow easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches.
