The SQP211-14-6-4-86ADC2-18-S106 pump belongs to the Low Noise SQP Vane Pumps series and is manufactured by Vickers for hydraulic automation tasks that require quiet and steady flow. Its design number is 18, identifying the specific engineering revision. The unit is arranged for Foot Mount (2) installation, simplifying alignment on a base plate. Rotation is clockwise, so coupling orientation is fixed for consistent shaft loading. Operation can start at a minimum speed of 600 rpm for low-demand cycles, while mineral-oil service permits speeds up to 1800 rpm for higher throughput. The maximum working pressure with mineral oil reaches 17.5 MPa, allowing the pump to support medium-pressure circuits. On the cover side the displacement is 12.8 ml per revolution, producing 12.8 L/min at 1000 rpm and 0.7 MPa, data used to size auxiliary actuators. With the foot mount attached the assembly weighs 49.5 kg, which affects handling and support requirements during installation.
The pump also contains a middle section that displaces 19.2 ml/r and delivers 19.1 L/min at the same reference speed and pressure, providing an additional flow path for secondary functions. The shaft side offers the largest capacity, moving 45 ml per revolution and yielding 43.3 L/min at 1000 rpm and 0.7 MPa to supply primary actuators with higher volume demands. When phosphate-ester fluid is selected the allowable speed is limited to 1200 rpm, and the same 1200 rpm ceiling applies for water-glycol operation; these ratings guide motor selection when fire-resistant or water-based media are required. The three displacement sections combine to furnish staged delivery, letting designers allocate hydraulic power to separate machine functions without adding extra pumps.
