Aquatec Surface Diaphragm Pump - 115VAC (5513-1E12-J526)
Aquatec's 5513 Surface Pump delivers powerful flow rates up to 4.9 gallons per minute and up to 70 psi. Its patented 5-chamber diaphragm and piston design allows for higher flows than the comparable 3-chamber ShurFlo alternative - and at a lower cost. It operates exceptionally quietly and with minimal pulsations.
The Aquatec 5513 is commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase pressure when required. It features an integrated pressure switch that enables the pump to work "on demand." As water is demanded downstream, the pressure in the line drops and the built-in pressure switch automatically turns the pump on to re-pressurize the line. Once water is no longer demanded downstream, the pressure in the line builds, and when it reaches 60 psi the pressure switch automatically stops the pump.
This surface pump is designed for intermittent duty, but can be run continuously for about two hours at a time. It is also able to run dry. Includes a 6' power cord with standard U.S. three-prong plug.

Although Aquatec is a relative newcomer to the solar water pumping market, they have been leaders in related fields including water treatment, medical laser equipment heat exchange, and medical endoscope reprocessing water supply since 1976. Aquatec's manufacturing and materials sourcing is all-American and does not depend on foreign suppliers for parts. All wet parts are NSF 018 drinking water safe.
Outstanding lifespan - Aquatec's surface pump brushes have been carefully selected to maximize life. Robust motor design with front and back bearing support, unlike the front bearing and rear bushing support found in many other brands. Heavy duty Honeywell micro switch is rated to 1.5 million cycles; the switch will last much longer than other brands. Proprietary diaphragm enhancements - including coated wobblers, diaphragm support backer, and specially selected santoprene - extend pump life as well.
Easy integration - ½" female NPT threaded ports for easy use with commonly available fittings.
