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, Any other pressurization system Features: SEAFLO DC Diaphragm pump is specially made for RV/MARINE Yachts and any other pressurization system. All SEAFLO pumps have been strictly tested and inspected by QC department to guarantee proper operation. The patented design delivers smooth，consistent flow at all ranges of operation, while drawing low current. The balanced motor design incorporates precision ball bearings for long life, motor is equipped with an integral thermal breaker. All marine duty pumps have sealed switches and are finished with a Electro Coating to inhibit corrosion. Marine duty fresh water pumps are enclosed to prevent incidental moisture from entering and when installed correctly, Marine Duty Fresh Water Pumps provide years of quiet operation. A SEAFLO pump in combination with a low backpressure water system can exceed all expectations. Functions: a) Motor Voltage: 12/24V DC b) Max Flow rate: 20lpm (5.5gpm), can be adjusted from 3.0-20lpm (0.8-5.5gpm) as required. c) Max Pressure: 60psi (4.2bar), can be adjusted from 10psi (0.6bar) to 60psi (4.2bar) as required. d) SFS51-01inlet strainer for your choice. Inlet/Outlet fitting: 13mm pyramid hose barb, 1/2 NPT thread fitting 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)
