GB-2228 Single-Threaded High-Pressure Water Diaphragm Pump with Right-Side Outlet

The GB-2228 high-pressure diaphragm pump is a miniature DC diaphragm pump designed specifically for high-pressure water supply, spray pressurization, and fluid transfer systems. Powered by a 12V DC motor and featuring a high-performance diaphragm structure, it delivers a maximum flow rate of 2.6 L/min and an output pressure of up to 90 PSI (5.5 Bar), ensuring stable water supply while maintaining low energy consumption and quiet operation.
This model features a design combining a threaded outlet port on one side with a hose barb connection, accommodating both standard piping connections and quick hose installation to suit various equipment configurations. The pump offers excellent self-priming capabilities—allowing for startup without manual priming—and operates stably under high-pressure conditions. With the fluid section completely isolated from the motor, the pump ensures superior leak resistance and a long service life.
The GB-2228 is widely used in applications such as portable cleaning equipment, smart spraying systems, water purification units, coffee machines, automatic water supply systems, garden irrigation equipment, and RV water systems. It serves as an ideal fluid transfer solution—combining performance and reliability—for equipment manufacturers requiring stable pressure output, compact design, and easy installation.
