This single-phase submersible drainage pump is designed for continuous duty with clean water containing suspended solids up to 10 mm. It is ideal for residential pits and rainwater collection systems where the liquid temperature does not exceed 35°C and pH levels are between 6 and 11.\u003c\/p\u003e\u003cp\u003eHydraulic output reaches a maximum flow rate of 400 L\/min and a total head of 13.5 m. Powered by a 0.75 kW 240v motor drawing 4.5 Amps, the pumped liquid provides continuous motor cooling during operation. This thermal management configuration ensures the unit can operate safely during extended drainage tasks even when only partially submerged in the standing position.\u003c\/p\u003e\u003cp\u003eWater passes through a single open impeller manufactured from cast iron, housed within a cast iron pump body. The vertical threaded delivery port facilitates direct pipework connection, while the integrated AISI 304 stainless steel filter protects internal hydraulics from debris. Automated service is managed by a float switch, which requires a minimum water level of 425 mm for activation.\u003c\/p\u003e\u003cp\u003eMechanical durability is provided by a GJL 200 cast iron pump casing and an AISI 304 stainless steel motor jacket. Motor protection is achieved via a double mechanical shaft seal with an interposed oil chamber containing food-grade oil. The induction motor features an incorporated capacitor, thermal protector, and a triple impregnation humidity-proof dry winding for long-term reliability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRobust cast iron pump casing and impeller provide durability for domestic and civil drainage systems.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with an integrated oil-filled chamber enhances motor protection during service.\u003c\/li\u003e\n\u003cli\u003eSeal lubrication utilizes specialized oil safe for food and pharmaceutical machinery within the oil chamber.\u003c\/li\u003e\n\u003cli\u003eThe pumped liquid dissipates motor heat during operation, facilitating safe performance at low water levels.\u003c\/li\u003e\n\u003cli\u003eOpen impeller design manufactured from GJL 200 cast iron handles suspended solids up to 10 mm.\u003c\/li\u003e\n\u003cli\u003eSingle-phase 240v motor winding includes a built-in thermal protector and an automatic float switch.\u003c\/li\u003e\n\u003cli\u003eMotor features triple impregnation humidity-proof dry winding designed in accordance with EN 60335-2-41.\u003c\/li\u003e\n\u003cli\u003eCertified IP X8 protection rating facilitates continuous duty immersion at depths reaching up to 5 meters.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50914706620663,"sku":"GQRM 10-14","price":1111.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-gqrm-10-14-cast-iron-float-switch-submersible-drainage-pump-stream-water-open-impeller.png?v=1783147722","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-gqrm-10-14-cast-iron-float-switch-submersible-drainage-pump-stream-water-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
