M.W. Watermark Retrofit Hydraulic Power Unit (HPU)
Another way that we work to get you back up and running quickly is through innovations in equipment. If you are in need of an emergency fix for your hydraulic pumping system, then M.W. Watermark has a great solution for you.

M.W. Watermark has designed a stand-alone Hydraulic Power Unit (HPU) which serves as a universal retrofit for older-style filter presses. The HPU is available with either a 7 or an 11-gallon reservoir. These two size options should cover most types of filter presses, from 630mm to 1200mm in filter plate size. Simply attach a supply airline and two hydraulic cylinder lines to the HPU to get your filter press back up and running. As always, we will continue to stock all air over oil hydraulic parts for JWI and other manufacturer’s presses.
