Shanchuan Qingtuo is a hydraulic power pack manufacturer in Wuxi, China. We supply energy-saving hydraulic power units for machine tools, workholding and machinery OEMs.
SHANCHUAN QINGTUO / ENERGY-SAVING HYDRAULICS
Short motions. Long holds. A different way to use hydraulic power.
Build pressure when the machine needs it. Hold with an accumulator. Recharge on demand. Explore a hydraulic system built around your working cycle.
A better working cycle
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.

How it works
The motor drives the pump to deliver the pressure and flow required for the machine movement.
During a suitable holding phase, the motor stops and the accumulator supports pressure holding.
Pressure feedback triggers the motor to restart below the set threshold, then stop at the target pressure.

Inside our workshop
Meet the hardware / SC-QT
SC-QT vertical and SC-QT horizontal power units for CNC machinery and fixtures. Compare nine configurations from the current catalogue.
Manufacturer catalogue values for nine SC-QT configurations. Confirm supply, interfaces and the operating point with engineering.
Compare SC-QTClear answers for the decisions that matter.
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.
Start with the machine application, pressure, flow, holding time, supply voltage and available space. Our engineers review the configuration and interfaces for your equipment.
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.
At booth 2.1H-C011, Jiangsu Shanchuan presented Shanchuan Qingtuo hydraulic power units and a comparison demonstration, welcomed international visitors and outlined plans for follow-up discussions.

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.
