The Additel ADT 917 is a hand-operated pneumatic pressure test pump engineered for generating pressure from 95% vacuum to 1000 psi (70 bar). It is designed for field or laboratory calibration of pressure gauges, transmitters, transducers, and switches.

A high-quality screw press enables fine pressure adjustment with resolution up to 10 Pa (0.1 mbar). The specially designed shut-off valve maintains exceptional stability during calibration, while the built-in gas-liquid isolator protects internal components from moisture and dirt, reducing maintenance requirements.

Two hand-tight quick connectors for test and reference gauges allow easy connection and disconnection without tools or PTFE tape. The pump is available with multiple pressure port options: 1/4 NPT, 1/2 NPT, 1/4 BSP, 1/2 BSP, or M20×1.5 female.

Constructed with stainless steel ram and adapters, stainless steel/aluminum body, and Buna-N seals, the ADT 917 is built for durability. The piston volume is 27 ml (1.6 in³). At only 5.7 lb (2.6 kg) and compact dimensions of 5.5 × 7.8 × 12.4 inches (140 × 198 × 315 mm), it is highly portable.

Each unit includes 20 spare O-rings and an operator's manual. Optional accessories include a carrying case, adapter kits, hose test kits, and a maintenance kit.

Typical applications include calibrating pressure instruments in industrial plants, calibration laboratories, and field service environments. The pump is backed by a 1-year warranty.
