MJC Engineering Announces Green Hydraulic Power System

MJC Engineering, a builder of CNC metal spinning, rotary forge and flow forming machines, announced the development of its hydraulic power system, Green Hydraulic Power. This system is designed to provide higher machine yield, reduce noise emissions by 20 dBA, generate less heat, and produce a shorter cycle time on various machine types. MJC is a major supplier to automotive, aerospace and the wheel industry.


Green Hydraulic Power is offered as standard on the hydraulic power units provided on MJC machine builds and utilizes the unique Siemens SINAMICS variable speed servo pump drive.  The company has subsequently developed a subsidiary unit, Green Hydraulic Power, Inc. and separate sales force for the unit’s development in the market.

The applications are many for this new system concept as almost all machine tools using hydraulic power are thus candidates for variable speed servo pump drive technology. Injection presses, materials handling equipment, stamping presses, other metal forming machines and more can utilize Green Hydraulic Power.

The system has control data output from the onboard diagnostic capability in the drive that supplies information for a predictive maintenance protocol in an Industry 4.0 scenario. The basics of pressure, temperature and acceleration data measurement are standard, with additional data outputs on oil level, filter condition, running efficiency and other parameters available.

This new line is offered in 100, 200 and 300-gallon tank units rated up to 4000 PSI and is available in two styles, one with a VFD, asynchronous motor and internal gear pump, while the second has a servo inverter, synchronous servo motor and internal gear pump.
