Sealing is provided by a double mechanical shaft seal with an oil chamber containing oil for food machinery and pharmaceutic use. The motor features a triple impregnation humidity-proof dry winding, built-in thermal protector, and capacitor incorporated in the float switch.\u003c\/p\u003e\u003cp\u003eDesigned for domestic water supply from wells or tanks, the unit is used for rainwater harvesting and garden irrigation with clean liquid at temperatures up to 35°C. It supports continuous duty service and is compatible with wells having a 140 mm minimum diameter. The design allows for installation in the standing position within reservoirs and tanks.\u003c\/p\u003e\u003cp\u003eMulti-stage hydraulics utilize stainless steel impellers housed within stage casings to move clean liquid through the pump. An integrated suction strainer prevents the entry of solids with a diameter bigger than 2 mm, protecting the internal components from wear. This configuration supports reliable flow behavior during submerged operation.\u003c\/p\u003e\u003cp\u003eHydraulic output reaches a maximum head of 91 m and a maximum flow rate of 75 L\/min. Powered by a 2.2 kW single-phase 240v motor, the unit draws a rated current of 14.3 Amps. Cooling is provided by the pumped liquid flowing around the motor, permitting safe operation during partial submersion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConstructed using chrome-nickel stainless steel AISI 304 for all internal and external fluid-contact parts.\u003c\/li\u003e\n\u003cli\u003eMotor sealing is achieved using a double mechanical shaft seal with an oil-filled chamber for protection.\u003c\/li\u003e\n\u003cli\u003eMechanical shaft seal lubrication is ensured by oil for food machinery and pharmaceutic use in the oil chamber.\u003c\/li\u003e\n\u003cli\u003eThe pumped liquid dissipates motor heat during operation, facilitating safe partial immersion.\u003c\/li\u003e\n\u003cli\u003eIntegrated suction strainer restricts the entrance of solid debris with a diameter bigger than 2 mm.\u003c\/li\u003e\n\u003cli\u003eSafe electrical service is provided by a built-in thermal protector and a capacitor incorporated in the float switch.\u003c\/li\u003e\n\u003cli\u003eTriple impregnation humidity-proof dry winding ensures motor reliability under continuous duty cycles.\u003c\/li\u003e\n\u003cli\u003eIPX8 protection rating for continuous immersion up to 20 meters with included 15m power cable.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50912348831991,"sku":"MXSM 309CG","price":2531.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-mxsm-309cg-stainless-steel-multi-stage-submersible-pump-ground-water-supply-float-switch.png?v=1783066091","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-mxsm-309cg-stainless-steel-multi-stage-submersible-pump-ground-water-supply-float-switch","provider":"Foundation Pumps","version":"1.0","type":"link"}
