They are recommended for pumping clean water without abrasive particles, and liquids that are chemically non aggressive for the materials of which the pump is made. As a result of their reliability, compact, economy and the fact that they are easy to use, they are widely used domestic water, automatic boosting, water tower supply, well water lifting, solar hot water boosting. 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. The pumps should be installed in enclosed environment, or at least sheltered from inclement weather.
