The 55 Series is the Heavy-Duty water pump. It provides high volume water flow with reduced pump cycling, thanks to the large five-chamber diaphragm. These models are designed to run on water systems with no accumulator tank necessary, and up to five fixtures. It is also suited for use with a holding tank water system, as may be found in a boat, RV or remote cabin. All are fitted with a built-in pulsation dampening by-pass to control unwanted cycling and noise. The 55-Series pumps are self-priming, and can run dry without damage, performance reliable and low current. This automatic demand water system pump has a built-in pressure switch, which automatically starts and stops the pump when the faucet is opened and closed. They are easy to install service and winterize.
