120W Fully Automatic Circulation Pump Water Return Pressure Boost Adjustable Speed Shielded Pump Home & Agricultural Irrigation

Product Application:This pump is used for cold and hot water circulation and pressurization below 100 degrees Celsius. Especially for shower systems, due to low water pressure, ignition is difficult or the water pressure is unstable, which easily causes fires. Installing and using this pump can completely solve the problem. It can be used for increasing pressure and supplying water for household systems with low water pressure, solar water heaters, boiler water circulation pressurization, industrial equipment liquid pressurization circulation, air conditioning and refrigeration system circulation pressurization.Features:The pump's structure uses a stainless steel sleeve to completely shield and isolate the internal iron core of the motor from the water. It eliminates the traditional mechanical seal structure, completely solving the problem of water leakage in conventional water seals. The structure uses graphite bearings, ceramic or stainless steel shafts, which are wear-resistant, corrosion-resistant, naturally lubricated by water, and have low noise. It operates at full range of pressure and voltage without load. As long as it is used correctly, the service life is long. All materials inside the motor are made of high-temperature high-quality materials, suitable for hot water circulation pressurization systems. The pump can be equipped with a water control automatic switch, making it more convenient to use. The design of the pump's wiring box includes three-speed speed control switches. It can be adjusted and regulated according to different user environments and requirements.Operating Conditions:1. Temperature range of the conveyed medium: 0 degrees to 100 degrees;2. High environmental temperature: +40 degrees;3.Medium requirements: Clean, free of solid impurities, free of mineral oil, non-viscous, non-corrosive.4Chemical properties: Neutral in nature, non-explosive liquid similar to water (with a high content of ethylene glycol at 30%);5. For extracting other liquids, consult the manufacturer first;6. Maximum working pressure: 10 bar7. Minimum inlet pressure:At a temperature of 50 degrees: 0.05 barAt a temperature of 95 degrees: 0.3 barAt a temperature of 110 degrees: 1.0 barThe above values are only applicable at an altitude of 300 meters. For higher altitudes, increase the pressure by 0.01 bar for every 100 meters. To prevent cavitation and generate noise, maintain a limited inlet pressure.8. Rated voltage is between -10% and 10%. If the voltage is too low, it will result in extremely slow or inability to start, rapid heating, resulting in a low head and low pressure.
