35VQ30A 1B20

The 35VQ30A 1B20 vane pump belongs to the VQ Thru-Drive Vane Pumps series and is manufactured by Vickers. Intended to supply pressurized fluid for hydraulic automation, it provides a geometric displacement of 97.7 cm³ per revolution, letting controllers calculate flow directly from shaft speed. The pump turns clockwise, matching right-hand drive arrangements found in many industrial power units. Fluid enters through an SAE four-bolt flange on the inlet port and leaves through a matching SAE four-bolt flange positioned 90° counter-clockwise from the inlet, which simplifies right-angle manifold layouts. Continuous service is supported up to 210 bar, enabling the pump to feed actuators that operate near 3,000 psi without stressing internal components.

At 1,200 rpm and 7 bar, the pump reaches a rated capacity of 30 US gpm, supplying steady circulation for low-pressure standby modes. When driven to its maximum point, it delivers 211.5 L/min, equivalent to 55 US gpm, and consequently draws 87.7 kW, or 117.5 hp, information required for sizing prime movers and electrical supplies. The assembly weighs 22.7 kg, so one technician can install it on a thru-drive motor or gearbox without hoists. These flow, power, and weight figures guide designers when selecting a pump for centralized hydraulic systems that must maintain reliable delivery across variable demand profiles.
