PW750 SHIMGE pump

Automatic self-priming electric pumps of the PW and PW-Z series with a vortex impeller are designed for automatic pumping of clean water without abrasive inclusions and non-aggressive liquids similar in their properties to water and are intended for domestic use. The electric pumps of the PW and PW-Z series are perfectly suitable for solving the problems of automatic continuous water supply of country houses, cottages, household and commercial facilities, as well as the organization of irrigation, washing and irrigation with water supplied from water pipes, wells, boreholes and drainage tanks. Electric pumps PW and PW-Z are designed for pumping both cold and hot water (up to 90 ° C). This allows the use of electric pumps of these series in solar water heating systems, as well as hot water supply systems. Electric pumps of the PW series are controlled only by means of a mechanical pressure switch. The electric pump cannot automatically stop at very low values of water pressure or flow rate. The electric pumps of the PW-Z series use an electronic stabilization circuit: flow and pressure data obtained from the flow switch and pressure switch built into the pump housing are analyzed by the control unit. Based on the received data, the control unit automatically gives the command to start or stop the pump, thereby ensuring a stable water supply. Electric pumps of the PW-Z series have built-in dry running protection. OPERATIONAL LIMITATIONS: Mains voltage: 1 ~ 220V (±10%), 50Hz. Maximum temperature of the pumped liquid: up to +90 °C. Ambient temperature: from +1°C to +40°C. Maximum working pressure: 5 bar. pH of the medium: 6.5 – 8.5. Suction height: up to 8 m. Electric motor: silent, closed type with external ventilation and built-in thermal protection. Motor protection class: IPX4. Insulation class: B. The electric pump must be installed in a dry, ventilated room, excluding the ingress of water and the formation of condensate in the electric pump engine. Pumped medium: pure water that does not contain long-fiber inclusions with a maximum content of suspended solids up to 0.1% and a maximum size of 0.2 mm. materials: Pump body: cast iron. Connection: cast iron. Engine housing: aluminum. Impeller: brass. Shaft and rotor: n/W steel 304 + steel 45 (Cs45#). Mechanical seal: Graphite/Ceramics/NBR. Motor winding: copper. FEATURES OF THE PW MODEL: Automatic self-priming vortex pump. Electronic pressure sensor. An expansion tank integrated into the pump housing. Compact design, easy installation and maintenance. FEATURES OF THE PW-Z MODEL: Automatic self-priming vortex pump. Intelligent control system. Protection against "dry running". Redundant control system for stable pressure and flow. When the pump is idle for 3 days, automatic switching on for 10 seconds, to protect against jamming. Special anticorrosive coating of the pump housing with enamel. Compact design, easy installation and maintenance. Plastic pump base, to ensure convenient installation and reduce noise.
