VQ20 VQ25 VQ35 VQ45 sizes with many different flow code. VQ pump use the floating side plate structure, it will compensate the end-face clearance by automatic, and enhance the volumetric efficiency, pressure is a little more higher, the structure improved the seizure resistance, so the working life is more longer Working Conditions The temperature of hydraulic oil: -10-60℃ Viscosity of hydraulic oil: 17-68cst Oil filter precision: 25um no less than
