12V Water Pump 80W Automatic Pressure Switch Self‑Priming Diaphragm Pump 5.5L/min for RV Boat Garden

12V Pressure Water Pump Model 0142YA1280 Key specifications Model: 0142YA1280 Product name: pressure 12v water pump Voltage: DC 12V (24V model also in stock) Power: 80W Open flow rate: 5.5 L/min Maximum working pressure: 79.75 PSI (5.5 bar) Setting pressure: 130.5 PSI (9 bar) Pump type: reciprocating diaphragm pump, selfpriming Control: automatic pressure switch Allowed medium temperature: 0 to 70 C Suction vertical distance: 1.5 m Fuel: electric Use: general purpose pressure pumping Why this pump is useful Delivers consistent pressure in a compact 12V package, suitable for battery powered or vehicle power systems. Automatic pressure switch provides hands operation by starting and stopping the pump to maintain system pressure. Selfpriming diaphragm design simplifies setup and enables reliable suction from shallow sources up to 1.5 m. Broad operating temperature range and a 5.5 L/min flow rate make it suitable for a variety of light to medium duty tasks. What makes it stand out pressure capability up to 5.5 bar combined with a compact 80W motor provides an efficient balance of pressure and flow. Reciprocating diaphragm construction offers stable pressure delivery and is well suited for intermittent duty applications where pressure control is required. Available in 12V and 24V configurations to match different electrical systems. Typical applications Mobile spraying and agricultural sprayer systems for small plots, greenhouses, and pest control. Water pressurization for RVs, boats, and camper vans to supply taps and showers from onboard tanks. Pressure boosting for garden irrigation, car washing, and small pressure cleaning setups where a compact, selfpriming pump is needed. Installation and compatibility notes Designed for DC 12V power systems; a 24V version is available if required. Ensure correct wiring and a suitable fuse or circuit protection when integrating with battery or vehicle electrical systems. Observe the 1.5 m maximum suction lift and the recommended medium temperature range for reliable operation. This 12V pressure water pump provides a practical, compact solution for applications that need controlled pressure, automatic operation, and easy installation in DC powered systems.
