Servo motor pump

——Low Oil Temperature: Servo motor only works when necessary, decreases system oil temperature and saves cooling water consumption effectively.
——High Energy efficiency: In condition of ideal working state, power consumption is 20%-80% less than that of traditional fixed pump, saving the energy effectively.
——Fast Response:  With stable performance, servo motor control system is equipped with precise pressure feedback device, improving motion response and production efficiency.
——Low Noise:  Different from traditional fixed pump system, servo machine is only works when necessary, offering you a quieter working place with less noise.





Variable pump machine

1、 Energy Saving: In the ideal working state, power consumption is 30%-60% less than that of ordinary fixed pump, saving the energy effectively.
2、 Oil Saving: Provided with imported high quality oil filter, longer life of hydraulic oil.
3、 Water Saving: Without overflow heating, low oil temperature saves cooling water and prolongs the service life of sealing parts.
