SQP01-4-1A23-15-S87

The SQP01-4-1A23-15-S87 pump is manufactured by Vickers and belongs to the Low Noise SQP Vane Pumps series. It supplies hydraulic power for automated machinery while limiting airborne sound levels in plant environments. The unit is arranged for foot mounting, and its base is oriented to the right at the three o’clock position to align with common motor brackets. Clockwise rotation accommodates right-hand shafts typical of IEC and NEMA motors. The lowest permissible operating speed is 600 rpm, which guarantees film lubrication of the vanes during idling cycles. Mineral-oil-based hydraulic fluid is required so seal compounds and bearing materials remain stable over long service intervals. The suction flange accepts a 1-1/4 inch SAE J518c connection to support unrestricted inlet flow, and the mounting face conforms to the same SAE J518c standard pressure pattern. With the foot bracket installed, the pump weighs 19.0 kg, so lifting points must be chosen accordingly.

At 1000 rpm and 0.7 MPa, the pump delivers 12.8 L/min, providing a predictable source of flow for proportional valves and small cylinders. The pressure outlet is placed opposite the suction side under code A, a layout that keeps the discharge line clear of the inlet piping. Fluid exits through a 3/4 inch SAE J518c flange, allowing direct attachment of standard pressure hoses. A top running speed of 1800 rpm means the pump can be driven by four-pole motors without over-speeding. The housing and cartridge assembly are rated for working pressures up to 17.5 MPa, granting enough margin for most industrial press circuits. Adhering to these limits avoids premature wear and maintains the low noise characteristics that define the SQP family.
