Customers’ orders are never accidental; they represent numerous advanced enterprises pursuing efficient, energy-saving and dependable production. Our energy-saving hydraulic power units are selected for their unmatched core strengths as below:

Revolutionary Energy Conservation

Zero Near Power Consumption During Standby Hold

Powered by intelligent shutdown & pressure retention technology, the main motor automatically stops once tooling completes stroke and enters pressure-holding standby. Unique accumulator-based pressure-maintaining circuit or low-power supplementary pressurizing unit sustains required system pressure, eliminating massive power waste caused by continuous idling of conventional hydraulic stations.

Tangible Energy Savings

Field tests verify power consumption drops by 10%~30% under holding standby conditions, delivering immediate electricity cost reduction and prominent environmental benefits for clients.

Superior Stable Pressure Retention

Constant Long-term Pressure Safeguard

High-performance accumulators and precision pressure control valves maintain set pressure with high accuracy for extended periods even after main pump shutdown, stabilizing clamping force and securing consistent product quality.

Fast Smooth Restart

The system responds instantly and starts up seamlessly to resume production without disrupting production cycle whenever operation resumes.

Extended Service Life & Minimal Maintenance

Less Wear from Static Standby

Stopped main motor at standby cuts runtime and abrasion of motors, pumps and related components to prolong service life of key parts besides power saving.

Lower Oil Temperature & Enhanced Reliability

Reduced idle heat generation slows hydraulic oil degradation, improves overall system stability and reliability while cutting cooling demands and maintenance expenses.

Customized Professional Design

Bespoke Non-standard Configuration

Custom-engineered per clients’ tooling structure, layout, pressure and flow parameters for seamless integration and optimal operational performance.

Reliable Premium Build

Premium component sourcing, standardized production process and comprehensive factory testing guarantee consistent durability and dependability in line with Shanghai Yangyu Hydraulic’s quality standards.

Intelligent & User-friendly Control

One-touch Operation with Visible Status

Optional PLC & HMI intelligent control enables straightforward operation; running status, pressure readings and fault alarms are displayed clearly.

Multi-layer Safety Protection
