Designed for domestic water supply, garden irrigation, and rainwater harvesting, this pump handles clean cold water at temperatures reaching up to 35°C. It is rated for continuous duty operation in the standing position.\u003c\/p\u003e\u003cp\u003eOperating on a 240v single-phase supply, the 0.45 kW motor reaches a maximum head of 29.5 m and a maximum flow rate of 75 L\/min. Drawing a rated current of 3.5 Amps, internal cooling is achieved by fluid circulating between the motor jacket and outer shell, which allows for safe service during partial submersion.\u003c\/p\u003e\u003cp\u003eMulti-stage hydraulics feature stainless steel impellers for clean water transfer through the AISI 304 casings. A base-integrated suction strainer restricts the entrance of solid particles with a diameter bigger than 2 mm, protecting the internal components from debris. The unit fits wells with a 140 mm minimum internal diameter.\u003c\/p\u003e\u003cp\u003eMechanical sealing is provided by a double mechanical shaft seal with an oil chamber containing oil for food machinery and pharmaceutic use. The construction features a chrome-nickel stainless steel AISI 304 external jacket. It includes a capacitor incorporated in the float switch, a built-in thermal protector, and a triple impregnation humidity-proof dry winding.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eManufactured with all internal and external parts in contact with fluid in chrome-nickel stainless steel AISI 304.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with oil-filled chamber provides motor protection and lubrication for the shaft seal.\u003c\/li\u003e\n\u003cli\u003eSeal lubrication is provided by oil for food machinery and pharmaceutic use in the integrated oil chamber.\u003c\/li\u003e\n\u003cli\u003eCooling is provided by the pumped liquid flowing around the motor to allow safe operation at low water levels.\u003c\/li\u003e\n\u003cli\u003eSuction strainer prevents the entrance of solid debris with a diameter bigger than 2 mm.\u003c\/li\u003e\n\u003cli\u003eAutomated service is enabled by an integrated float switch with an incorporated starting capacitor.\u003c\/li\u003e\n\u003cli\u003eMotor winding features a triple impregnation humidity-proof dry construction according to EN 60335-2-41 standards.\u003c\/li\u003e\n\u003cli\u003eSuitable for continuous duty operation with IPX8 protection for immersion up to 20 meters.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50912348274935,"sku":"MXSM 303CG","price":1560.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-mxsm-303cg-stainless-steel-multi-stage-submersible-pump-deep-well-supply-float-switch.png?v=1783066076","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-mxsm-303cg-stainless-steel-multi-stage-submersible-pump-deep-well-supply-float-switch","provider":"Foundation Pumps","version":"1.0","type":"link"}
