28W Electromagnetic Water Pump 110V Black, Low Noise Reflux Valve Design for Coffee Machine and Steam Iron

Compact 28W Electromagnetic Pump with Reflux Valve Key benefits Reliable flow control and stable water output for small appliances and fluid transfer systems. Built with a reflux valve so the pump can continue running safely if the outlet is blocked; liquid is routed back and circulation prevents immediate pressure buildup. Low noise operation below 60 dB and fast heat dissipation for quieter, longer service life. Small, lightweight design at 150 g for easy integration into tight spaces. Specifications Power: 28W Available configurations: Black 110V 28W; AC 100V 50Hz (black); AC 220V 50Hz (blue) Duty cycle: 1 minute on, 1.5 minutes rest Maximum pressure: approximately 0.35 MPa Maximum flow: 250 cc per minute Noise: less than 60 dB Input: hose connection Weight: 150 g Packing: 14 units per box or 70 units per box Features that matter Reflux valve design protects the system when the outlet is blocked by allowing internal recirculation rather than forcing the motor to stall. Accurate flow and pressure capability support consistent performance under varying load conditions. Compact electromagnetic motor construction provides efficient power, rapid heat dissipation, and stable operation in intermittent duty cycles. Typical applications Coffee machines and espresso makers for controlled water delivery and pressurized circulation. Steam irons and steam cleaners where consistent pressure and low noise are required. Sewage sampling and general liquid transfer tasks that need a compact, durable pump for moderate flow rates. What this pump solves Eliminates interruption risks when outlets become blocked by using the reflux path to prevent pressure spikes. Provides a compact, low noise solution for equipment that requires reliable, repeatable water delivery. Offers straightforward integration via a hose connection and lightweight form factor for retrofits and designs. Note The motor will continue running if the outlet is blocked; the reflux valve opens and the liquid circulates inside the pump in that condition.
