Air Shift Cylinder For DM-640 and DMD-25

Our actuators are specifically designed air actuators used to control hydraulic dump pumps.

The Permco Air Shift Cylinder is designed to convert a manual shift dump pump to an air shift dump pump. It can be used on all dump pumps similar to Permco ‘s DM-640 remote mount and the DMD-25 direct mount series. Its compact design allows it to be used with all air shift PTO configurations. The 997-00971A is extremely easy to install with very few parts and is designed for the tough service expected on a dump application.


Air actuators provide a cost efficient alternative to cable controls, which save labor and cost both at installation and by eliminating the service and maintenance issues associated with cable controls.
