A better working cycle

Pressure is needed. Constant motor operation may not be. We help machinery builders rethink the energy used between movements.

Energy savings. Lower running costs.

For short machine motions followed by long pressure holds. Supply oil for motion, stop during holding, and reduce idle power consumption and heat at the source.

Selected applications

Engineering in practice.

All applications

Explore our energy-saving retrofits for workholding, casting and packaging.

How it works

Power, only when needed.

01 — 02 — 03
01 / MOTOR ON

Build pressure

The motor drives the pump to deliver the pressure and flow required for the machine movement.

02 / MOTOR OFF

Hold pressure

During a suitable holding phase, the motor stops and the accumulator supports pressure holding.

03 / PRESSURE FEEDBACK

Recharge on demand

Pressure feedback triggers the motor to restart below the set threshold, then stop at the target pressure.

Our solutions

Start with the way your equipment works. Find the right path from the machine cycle to its hydraulic power unit.

FAQ

A few good questions.

Explore all 50 answers
What makes this hydraulic unit energy-saving?

For suitable intermittent pressure-holding duties, the pump builds pressure, the motor stops during holding, and pressure feedback triggers replenishment when needed. The result depends on the machine cycle, leakage and baseline system.

Can it work with my existing machine?

Start with the machine application, pressure, flow, holding time, supply voltage and available space. Our engineers review the configuration and interfaces for your equipment.

How do we verify the energy savings?

Compare the original and proposed units on the same machine and working cycle, using the same measurement boundary. Record energy use, pressure stability and operating conditions together.

Choosing a hydraulic power unit supplier

When comparing hydraulic power unit manufacturers or hydraulic power pack manufacturers, start with the machine cycle and interfaces, then agree the configuration and acceptance checks. For machinery OEM hydraulics, Shanchuan reviews motion, holding time, supply and installation requirements together before confirming a proposal.
