Hydratron Air Driven Liquid Pump DIDA 118/4-N-LO 23,600 PSI Max

The Hydratron DIDA 118/4-N-LO is a double-head double-acting air-driven liquid pump rated to a maximum working pressure of 23,600 PSI (1,628 bar). The CE-marked unit is manufactured by Hydratron Ltd, based in Cheshire, England, and serial number 44/6 is visible on the nameplate. The pump incorporates a dual-air-drive assembly with two large-diameter air pistons connected to high-pressure liquid plungers, enabling high-flow, positive-displacement output from a standard compressed air supply. A label on the air drive manifold block specifies a maximum air supply of 100 PSI (7 bar). The unit features a black-painted steel frame assembly with machined valve manifold blocks, copper hydraulic interconnect tubing, multiple instrumentation ports, and a brass-bodied hydraulic end section. Applications for this class of pump include hydrostatic pressure testing, chemical injection, hydraulic power generation, and high-pressure fluid transfer in oil and gas, aerospace, and industrial test environments. The N designation in the model suffix indicates standard nitrile main seals and check valve seals. The LO suffix indicates a low-pressure output configuration within the DIDA/DHDA 118 series. The pump is mounted on a wooden shipping pallet and is presented as removed from service industrial surplus. Model designation on the nameplate reads DIDA 118/4-N-LO; the equivalent Hydratron catalog designation for this series is DHDA 118/4.
