Internal-gear hydraulic pump HG series

for industrial applicationshigh-efficiencysingle-stage

The HG series of internal gear pumps, which demonstrate the high efficiency and low energy consumption characteristic of servo variable frequency drive (VFD) systems, are extensively utilized in various industrial machinery such as injection molding machines, footwear injection machines, die casting machines, hydraulic press brake machines and forklifts. These pumps are particularly well-suited for the energy-saving systems of servo VFDs. The design and development of these pumps are specifically aimed at fulfilling the high-pressure and high-speed demands of servo VFDs. Further optimization of the internal oil passages is achieved based on the analysis of suction and discharge flow under high-speed, high-pressure operating conditions. And, the dynamic stability of the pressure compensation mechanism is enhanced to improve the reliability of the products. application: for industrial machinery
