Jabsco’s updated and improved lineup of freshwater supply pumps are designed to provide years of satisfactory service in applications both large and small. HD (Heavy Duty) models include a wider diameter motor with a powder coated shell, cast aluminum endbells and lower housing to improve pressure capability and life. Available in configurations up to 6 GPM (23 LPM) and 60 PSI (4.1 BAR), these pumps deliver exceptional performance. Standard models provide good performance in an economical footprint. These configurations are available in 1-3 GPM, perfect for vessels with 1-3 outlets. A plastic housing protects the motors on these units from corrosion. Fitting an accumulator tank will increase the life of the pumps pressure switch as it avoids the need for the pump to start immediately each time an outlet is opened. It also prevents rapid on – off cycling of the pump and smooths the flow at your taps and showers.
