Hydraulic High Performance Pumps

Electric Pump HEM 7 for Hydraulic Wrenches
Technical data

With the new developed microprocessor-controlled automatic, the pump HEM 7 works in three stages even faster and more effective. An operation in manual mode is also possible. With the digital remote control as optional accessories, the process security is increased due to a second, independent digital pressure gauge. The big pump (volume 8l) has an integrated oil cooler.
The small pump (volume 3l) can be purchased with an optional oil cooler. Furthermore the pump design 120V or 800bar enable the worldwide operation of HEM 7. This hydraulic pump is suitable for hydraulic torque wrenches.
