SQP3-32-1B-18-S104

The SQP3-32-1B-18-S104 pump belongs to the Low Noise SQP Vane Pumps series and is manufactured by Vickers for hydraulic automation where quiet, steady flow is required. It is configured as a single fixed-displacement vane unit, so flow remains proportional to shaft speed and does not vary with downstream pressure changes. A geometric displacement of 100 mL per revolution establishes the exact volume delivered each turn, simplifying circuit sizing. The shaft rotates clockwise when viewed from the shaft end, setting the correct motor coupling direction. Continuous service is supported between 600 rpm and 1800 rpm; the lower limit prevents oil starvation at idle, while the upper limit secures vane tip velocity within permissible wear rates. A flange mounting interface lets technicians bolt the housing directly to a pump pad, shortening installation time and maintaining alignment.

The pump handles a maximum operating pressure of 17.2 MPa with standard petroleum fluids, allowing it to drive medium-pressure cylinders and motors without overstressing internal components. When fire-resistant phosphate-ester media are used, the allowable pressure falls to 13.8 MPa to protect seals that are less compatible with this fluid, and operation on water-glycol mixtures is limited to 15.9 MPa for similar longevity concerns. An outlet positioned 90° counter-clockwise from the inlet, coded B, aids compact plumbing by turning the discharge port toward the reservoir side of typical power units. These pressure and porting parameters give system designers clear limits for efficient circuit layout while retaining the low acoustic signature that defines the series.
