The PWA 2500 Series pump has been designed and developed as the “heart” and “workhorse” of your low-pressure mud system. This robust 2 1/ 2” diameter shaft, end suction, close grained cast iron pump, has been developed from both a dimensional and parts points of view to be totally interchangeable with most existing 2 1/ 2” diameter shaft pumps (i.e. Mission, Harrisburg). 
The PWA2500 series pump is designed to accommodate the 5” x 6” and 6” x 8 “liquid ends, with either 11” diameter or 14” diameter impellers, on one common power frame-thus minimizing your overall spare parts requirement. 
Because of total interchangeabilities of spare pares with other manufacturer's pumps, our PWA stock of parts is readily available for any 2 1/ 2” diameters shaft pump at any of your locations.
