◎ Max. working pressure 5 bar
◎ Liquid temperature up to +90℃
◎ Ambient temperature up to +40℃
◎ Voltage fluctuations should not exceed 10% of rate value
◎ Suitable for use with clean water that does not contain
abrasive particles or other similar water of liquid .
◎ Widely used domestic water , automatic boosting , water tower supply, well water lifting, solar hot water boosting.
◎ Compact design, easy installation
◎ Pressure and flow switch control automatically
◎ Pump body insert of stainless sheet 304
◎ Shaft extension is stainless steel 304
◎ The impeller of copper alloy
◎ High quality mechanical seal
◎ Intelligent control：Pump can supply stabilized water flow by automatically running. Through the water flow and water pressure data collected by flow switch and pressure switch, electronic unit control the pump running/stop, solve the frequently starting problems under low water flow, and completely inhibit frequently starting if water flows lower than 0.3m3 /h.
◎ Time delay start: 3-seconds delay on startup to prevent electric transient surge
◎ Dry-Run protection: Pump shut down if no water flows past pump inlet after running 6 minutes, when there is water flow past pump inlet, pump restart.
◎ Scale prevention: Pump will automatically run 10 seconds for scale prevention once per 3 days among outage period.
◎ Electronic switch: Long service life, and eliminate the "da da" noise caused by mechanical pressure switch
◎ Pump body internal enamel processing
◎ Single phase motor, copper wires, built-in thermal
protector, fully enclosed motor shell
◎ Continuous service S1
◎ IPX4 class protection
◎ Class B insulation
