SQP31-25-3-1AC-18 | Low Noise Double Fixed Displacement Vane Pump

The SQP series are low-noise vane pumps offered in single, double, or triple pumps, with 4 frame sizes, 16 series, and 31 models of different discharge displacements. The wide extent of this range allows users to select the optimum combination of discharge displacements for their circuits, leading to an energy efficient system.

• Lower noise - Offers very quiet and soft operational noise levels
• Greater flexibility - Multiple pump combinations of different displacements permits simpler circuit design compared to systems using one large displacement pump and provides greater flexibility in circuit design with low noise levels
• Maintenance friendly - Rotating element in cartridge kit form allows simple maintenance

Note - All standard options are omitted from the product model number.
