The SQP321-38-21-11-86DCD-15-S98 vane pump belongs to the Low Noise SQP Vane Pumps series and is produced by Vickers for hydraulic automation systems that require stable fluid supply. It is arranged as a triple-section unit, and the shaft-end section supplies 121 mL per revolution while producing 118 L/min at 1000 rpm and 0.7 MPa. Fluid exits this section through a D-oriented port positioned 90° clockwise from the inlet. The pump mounts on a flange, allowing rigid attachment to power units, and the drive shaft turns clockwise when viewed from the shaft end. Continuous operation is supported between 600 rpm and a maximum of 1800 rpm when mineral oil is used. Despite its multiple sections, the assembly weighs 62 kg, so it fits applications where medium mass components are acceptable.
The middle section of the same pump displaces 65 mL per revolution and outputs 65 L/min under the same test conditions; its C-oriented port sits 45° clockwise from the inlet to simplify manifold routing. The cover section contributes a further 35 mL per revolution and delivers 35 L/min at 1000 rpm and 0.7 MPa, with its own D-oriented port also set 90° clockwise from the inlet. Combining these three sections allows designers to draw multiple flow rates from a single housing while keeping noise levels low, matching the intent of the series.
