A pressure-controlled diaphragm design keeps water flowing on demand at 4 GPM (15 LPM) with a 60 PSI shut-off, and an integrated, sealed pressure switch starts and stops the pump automatically as fixtures are opened and closed. The heavy duty motor is cast in aluminum housing for a long working life under sustained high pressure, and an integrated bypass module reduces cycling while smoothing out flow at the tap. Dampening feet under the motor cut vibration for quiet running, and the pump is self-priming and can run dry without damage to the unit, so accidental tank-out situations will not harm the system.\u003c\/p\u003e\u003cp\u003eInstallation and servicing are simplified with quick-connect ports throughout: the pump comes equipped with an in-line quick-connect 40 mesh strainer to protect the diaphragm from debris and two 1\/2 inch quick-connect straight hosebarb fittings for plumbing into new or existing freshwater lines. It is suited to boats, RVs, and other vessels that need a reliable, quiet, on-demand freshwater supply.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e

Q401J-118S-3A is a 12V Jabsco Par-Max HD4 freshwater pump that supplies pressurized freshwater to onboard taps, showers, and fixtures on boats and similar vessels, delivering 4 GPM at up to 60 PSI before its pressure switch shuts it off.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Par-Max HD4 pump self-priming?\u003c\/strong\u003e Yes, the Q401J-118S-3A is self-priming and is also able to run dry without damage to the unit, so a temporarily empty tank will not harm the pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage does this Jabsco freshwater pump run on?\u003c\/strong\u003e This pump runs on 12V DC, matching a standard marine 12-volt house battery system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat flow rate and pressure does the Q401J-118S-3A deliver?\u003c\/strong\u003e It delivers an open flow of 4 GPM (15 LPM) and shuts off at 60 PSI once system pressure is reached, thanks to its integrated, sealed pressure switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat fittings are included with this pump?\u003c\/strong\u003e The Q401J-118S-3A comes with an in-line quick-connect 40 mesh strainer and two 1\/2
