Overview
The Additel 927 is a hand-operated hydraulic comparison test pump for generating 85% vacuum to 10,000 psi (700 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 7 lb (3.2 kg) and has a 245 ml (15 in³) reservoir.
ADT927 ships with oil as the default media (250 ml of mineral oil is included). Order ADT927W 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 9904-927 carrying case for the pump and two gauges.
Pumps from $3,064 (ADT927). ADT927W from $3,237. A maintenance kit (ADT927-MK) is listed with the variants.
