Overview
The Additel 925 is a hand-operated hydraulic comparison test pump for generating 85% vacuum to 6,000 psi (400 bar) in the field or laboratory. A patented screw press — with no check valve (non-returning valve) — lets you raise and lower pressure smoothly and avoids the leakage typical of most hand pumps, so maintenance stays minimal. The pump weighs 3.7 lb (1.7 kg) and has a 200 ml (12.2 in³) reservoir.
ADT925 ships with oil as the default media (250 ml of mineral oil is included). Order ADT925W when the media must be deionized water. Additel notes that stability is best with oil and that performance may decrease with water. Two hand-tight quick connectors take the reference gauge and the device under test — no PTFE tape or wrenches. Port choices are 1/4 NPT, 1/2 NPT, 1/4 BSP, 1/2 BSP, or M20×1.5 female. SET models add the 9901-925 carrying case for the pump and two gauges.
Compared with the Additel 920 pneumatic high-pressure pump (95% vacuum to 3,000 psi / 200 bar, air), the 925 is hydraulic and reaches 6,000 psi.
A maintenance kit (ADT925-MK) is listed with the variants.
