The original Peters and Russell Pumps – PAR, by Jabsco (now a division of XYLEM)
The original PAR (Peters and Russell) belt driven diaphragm water pumps by Jabsco are the grandfather of the electric boating pumps. 80% of all boats made today will have a PAR or Jabsco pump of one kind or another on-board the vessel.
The most common use for a pump on-board a vessel is to move fresh water from a tank to the fixture or from a tank or bilge to a thruhull.
This classic belt drive Jabsco “PAR” freshwater, shower and grey water pump utilizes the original Peters and Russell (Inc., Springfield, Ohio) design that has dependably served the marine industry for nearly 50 years! In many cases parts are still available and these ‘chugging’ diaphragm pumps just keep working and working. The biggest advantages of these pumps is their ability to digest some large materials and limited dry running.
The modern Jabsco PAR-Max pump series takes a different, if not more compact approach to pumping freshwater. The PAR-Max pumps are numbered 1-4 and will serve a variety of needs.
