Amarine Made 12v Diaphragm Self Priming Water Pump 17 L/m 4.5gpm 40psi High Pressure Water Pump 110V RV Water Pump with Filter for Motorhome,Caravan,RV,Boat,Marine,Agriculture

General: The water diaphragm pump provides high volume water flow.The four chamber high volume design, driven by a heavy-duty motor,produces flow rates up to 4.5GPM.With on-demand switch,the pump is self-priming,and can run dry without damage,performance reliable and low current.We also offers a variety of easy connect fittings and filters. Application: Yacht/RV/Caravan pressurized water system,Sprayer fixtures (Vehicle-mounted sprayers,electric sprayer),clean machine, Humidifier, Water purification, Medical apparatus Food beverage filling; liquid transfer and any other pressurization system. Features: 4 chamber diaphragm pump∙ Run dry capable for normal workloads∙ Self priming Intermittent duty∙ Automatic: controlled by pressure switch∙ Quiet Run Industry standard mounting pattern∙ Bypass: reduces cycling∙ Thermal protection Functions: a) Motor Voltage:12/24V DC, 110V/220V AC. b) Max Flow rate: 17lpm (4.5gpm), can be adjusted from 3.0-17lpm (0.8-4.5gpm) as required. c) Max Pressure: 60psi (4.2bar), can be adjusted from 10psi (0.6bar) to 60psi (4.2bar) as required. d) 4 kinds of inlet/outlet filter for your choice. Inlet/Outlet fitting: 12.5mm pyramid hose barb,1/4 NPT male thread fitting, etc for your choice. e) Protection: pressure switch protection: pressure-off protection or circumfluence switch protection. For the powered control you can choose pump without pressure protection. f) Duty Cycle: Intermittent (under different pressure the continuous working time will also be different)

• 【Applications】Could be used for:Yacht/RV/caravan pressurized water system;✺Sprayer fixtures (vehicle-mounted sprayers, electric sprayers);✺Cleaning machines, humidifier, water purification, medical apparatus;✺Food beverage filling & liquid transfer;✺Solar water system;✺Any other pressurization system
• 【Features】Higher operating pressure and/or lower amperage than competitive pumps Long life, no leaks;Thermal overload protection automatically stops motor should it overhear due to overload, with auto re-start feature
• 【Adavantages】The advantage of the automatic diaphragm pump with pressure switch: Self-prime,can run dry in short time,reliable function and lower flow rate. And can start automatically when turn on the water-tap,stops when turn off.Low noise; acid, alkali and corrosion resistant
