SEAFLO 43 Series DC Diaphragm Pump 12V/24V 3.0-11.3LPM 17-60PSI
The 43-Series pumps are designed for vessels requiring a smooth low flow, 12 or 24 volt DC pump at an attractive low price. These new pumps are internally grounded, four chamber diaphragm on-demand pumps with the performance characteristics to match the needs of a typical vessel with a shower, water heater and up to three faucets. It provides up to 3 gpm (11.3 lpm), all are fitted with a built-in pulsation dampening by-pass to control unwanted cycling and noise. We include quick-connect fittings for ease of pump installation. The new 43-series pumps provide exceptional flow and consistent water pressure to easily handle the demand of multiple outlets at one time. When onboard appliances are activated, the built in bypass design re-circulates back pressure into the pump to reduce cycling resulting in a quieter and smoother flow.
