SQP Series Intra-vane Pumps

This series vane pumps are high pressure and high performance intra-vane pumps.
1.Cartridge kits are entirely similar to those of VICKERS stable V series pumps which can be interchangeable with cartridge kits of SQP series
2.New configuration design gets an excellent performance in restraining pulsing and noise.
3.Strengthened pump housing design offers a better anti-vibration ability,which effect the remarkable low noise
