Sqp series vane pumps-applicable to industrial applicationgs of the cluster of lower noise vane pump This series vane pumpsare high pressure and high performance inra-vane pumps , which are specially developed for low noise workinf condition. They are widely applied in hydraulic system for machine-tools, presses, die casting machines, engineering, plastic injection moulding and other machineries, which call for lower noise. Features 1., cartridge kits are entirely similar to those of vickers stable v series pumps, which canbe interchanged 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.
