The F11-SOP21-21-11-1AA-18 vane pump belongs to the Low Noise SQP Vane Pumps series and is manufactured by Vickers for hydraulic automation systems. The design handles water glycol as the operating fluid so it can serve fire-resistant circuits without sacrificing lubrication. Clockwise rotation aligns the pump with standard right-hand prime movers, while a minimum speed of 600 min⁻¹ maintains stable vane seating during slow cycles. Operation may be increased to 1200 min⁻¹, providing a usable speed range for variable-frequency drives. A maximum working pressure of 17.5 MPa allows the pump to support medium-pressure actuator groups. Shaft torque is limited to 360 N·m to protect both the pump and the drive coupling from overload. A key width of 7.95 mm matches common metric drive shafts, ensuring positive power transfer. Flange-mount weight is 31.5 kg, permitting manual handling during installation and maintenance.
The shaft-end section delivers 66.7 L/min at 1000 min⁻¹ and 0.7 MPa, supplying the main hydraulic line with consistent flow, while the cover-end section provides 35.0 L/min under the same conditions for auxiliary functions. The No. 1 delivery port uses a 25.4 mm diameter and a nominal 1 in thread so the primary outlet can accept standard pipe fittings. The No. 2 delivery port is sized at 19.1 mm, or 3/4 in, offering a secondary flow path for parallel circuits. A suction port diameter of 63.5 mm with a 2-1/2 in connection lowers inlet velocity and minimizes cavitation at higher displacement rates. These port dimensions establish clear plumbing interfaces that allow the pump to be integrated quickly into reservoir-mounted or remote-mounted skids without custom adapters.
