Easy to install. Runs dry without system. Easy connecting system. Totally sealed, high stable pressure. Self-priming, silent running, low power consumption. Motor duty cycle will vary with load and ambient temperature. Applications: Car washing machine, solar energy water systems, remote control water equipment, places requiring frequent switch control, energy-saving applications, and more. This is a high-quality DC micro diaphragm pump. The water pump with a pressure switch automatically shuts off when the outlet pressure reaches the set point and restarts when pressure drops. Designed for energy conservation and frequent switching, it is widely used in general industrial equipment, medical devices, chemical equipment, farming (lawn and garden), recreational vehicles, special vehicles, boats, beverage systems, vehicle cleaning, carpet cleaning, floor cleaning, water purification, and water treatment equipment. Suitable for use as a chemical pump, metering pump, air conditioning pump, transfer pump, hydraulic test pump, sewage pump, and booster pump.
