The 4525V42A17 1DC22R pump belongs to the V Series Vane Pumps and is manufactured by Vickers for hydraulic automation circuits that require two independent flows from a single drive. The cover end displaces 55 cm³ per revolution so it can supply auxiliary circuits that demand moderate volume, while the shaft end displaces 138 cm³ per revolution to power the primary actuators. At 1200 rpm those displacements translate to 17 gpm on the cover end and 42 gpm on the shaft end, allowing each outlet to be matched to distinct flow requirements. The unit tolerates a continuous pressure of 172 bar (2500 psi), enabling operation in medium-pressure mobile or industrial systems without derating. These performance values are delivered by the vane design, which maintains smooth flow and limits pulsation under changing load.
The pump operates between 600 rpm and 1800 rpm, so designers can select motor speeds that balance response with noise and efficiency. Clockwise rotation viewed from the shaft end aligns with common electric motor conventions, reducing coupling changes during retrofits. A flange mount provides rigid attachment to power packs, and the inlet uses an FL1-28 flange kit to standardize connection size. Outlet 1 employs an FL1-12 flange positioned 90° clockwise from the inlet, while outlet 2 uses an FL1-8 flange set 45° clockwise, arrangements that simplify manifold routing when space is limited. All ports are cut with inch threads for compatibility with North American fittings, ensuring that the pump integrates quickly into existing pipework.
