Customers using Hydraulic Presses find that over the years their presses start to develop leaks on the Main Rams and Auxiliary Rams due to general wear and tear. Often the Rams will be scored and possibly oval in shape due to off-set loading of the press.
MPPS can bring these presses back to "as new" condition by re-machining the rams and replacing the Guide and Gland Bushes, and Seal Systems.
We offer a full service including design of new bushes and seals, removal of the press rams, re-machining and grinding the rams, supply of new parts, re-installation and testing.
A recent example of our capability:
The removal and refurbishment of the main ram, supply of new Guide Bushes and Seals for a Muller 1500 tonne Hydraulic Press at a leading supplier of Off Highway Equipment.
The main challenge in this project was removing and re-installing the Press Ram which due to its length and design was greater than the "day light" of the press.
The method of removal and re-installation of the Ram was simulated on our Solid Works CAD package to verify the planned method and special equipment would work within the confined space.
MPPS designed and manufactured a special Gimbal Clamping Unit mounted on a VersaLift to enable the Ram to be lowered down and swung out of the press cylinder. The Ram was refurbished, the bushes and seals fitted and the Ram assembly refitted into the press. The whole project including new parts was completed successfully within a tight time frame.
