This three-phase submersible pump is designed for rainwater collection where continuous duty is required. It handles clean water containing suspended solids up to 12 mm and liquid temperatures up to 40°C in the standing position.\u003c\/p\u003e\u003cp\u003eOperating on a 415v three-phase supply, the 1.5 kW motor delivers a powerful 500 L\/min maximum flow rate and reaches a maximum head of 18.4 m. The 2-pole induction motor draws 4.3 Amps and is cooled by the pumped water passing between the motor jacket and external jacket. This thermal management system supports safe operation during partial submersion.\u003c\/p\u003e\u003cp\u003eHydraulic performance is produced by an open single impeller configuration that enables the passage of suspended solids up to 12 mm without compromising flow. The vertical delivery port is ISO 228 G 1 1\/2 compatible, and the base of the unit features an integrated filter to protect the hydraulic components. Manual operation allows for drainage down to a residual water level of just 15 mm.\u003c\/p\u003e\u003cp\u003eConstruction features an external jacket, motor jacket, and filter manufactured from chrome-nickel stainless steel AISI 304. Sealing is managed by a double shaft seal with an oil chamber containing oil for food and pharmaceutical machinery. The motor features a double impregnation humidity-proof dry winding and is suitable for immersion depths up to 5 meters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eManufactured using AISI 304 stainless steel for the pump casing, impeller, and filter to ensure maximum service life.\u003c\/li\u003e\n\u003cli\u003eMotor sealing is achieved through a double shaft seal with an integrated oil chamber for enhanced protection.\u003c\/li\u003e\n\u003cli\u003eLubrication for the double shaft seal is provided by oil rated for food and pharmaceutical machinery use.\u003c\/li\u003e\n\u003cli\u003eThree-phase 415v 2-pole induction motor is designed for efficient drainage and water transfer applications.\u003c\/li\u003e\n\u003cli\u003eThe pumped liquid dissipates motor heat by circulating through the external jacket, facilitating safe partial immersion.\u003c\/li\u003e\n\u003cli\u003eOpen impeller design in chrome-nickel steel handles clean water with suspended solids up to a diameter of 12 mm.\u003c\/li\u003e\n\u003cli\u003eDouble impregnation humidity-proof dry winding ensures motor reliability during continuous submerged service.\u003c\/li\u003e\n\u003cli\u003eRated for IP X8 protection, allowing for permanent installation at immersion depths of up to 5 meters.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50912607142135,"sku":"GXR 12-20","price":1614.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-gxr-12-20-stainless-steel-submersible-drainage-pump-industrial-drainage-open-impeller.png?v=1783075419","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-gxr-12-20-stainless-steel-submersible-drainage-pump-industrial-drainage-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
