The Jabsco 31600-0094 Par Max 3 pressure-controlled freshwater diaphragm pump delivers 13 liters per minute (2.9 GPM) on 24V DC with an integrated pressure switch that cuts in at 20 PSI (1.4 bar) and cuts out at 40 PSI (2.8 bar) for consistent on-demand water pressure. Its self-priming multi-diaphragm design primes up to 1.5 m vertical lift, can run dry without damage, and uses an integrated bypass feature for smooth flow without an accumulator tank. Snap-in ports support 13 mm (1/2 inch) hose connections or Hep20 push-fit connectors, while thermal overload protection and corrosion-resistant materials support durable, quiet operation in demanding marine and mobile freshwater installations; availability is stated as no longer available with alternatives noted.
