The 55-Series is our heavy duty pump with the most robust pressure switch on the market. It provides high volume water flow with reduced pump cycling thanks to the large five-chamber diaphragm and a 2 gallon accumulator tank. It provides up to 5.5 gallons per minute. The 55-Series pumps are self-priming, can run dry without damage, and are performance reliable. 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. 
 
NOTE: This pump works best when paired with the included SEAFLO Accumulator Tank.
