Energy Saving Solution
for Hydraulic Presses
Conventional hydraulic presses consume large amounts of energy. Their
low efficiency results in significant energy wastage. However, today,
there is an innovative energy-saving solution for hydraulic presses that
can cut energy costs up to 60%.
A servo hydraulic pump combined with an AC servo motor can provide this
energy-saving. The internal gear servo pump provides variable volume
flows with a highly dynamic response and lower energy requirements.
Your Productivity Gains
•Significant energy savings- 30 to 60%
•Optimised programmable cycle as per need gives user flexibility
•Closed-loop speed, force and position control for superlative part quality
•Smaller hydraulic system, less oil, less maintenance, cleaner environment
•Much less heat generation, hence oil volume, heat exchangers drastically reduced
•Significantly quieter in operation
