SQP Series Single Pumps
SQP series vane pumps are high pressure and high performance intra-vane pumps, which are specially developed for low noise working 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.
