It is engineered for domestic and residential installations throughout Australia where macerating solids is required before the effluent enters the main sewer line. The unit handles liquids up to 35°C and provides a fixed vertical solution for collection pits where gravity drainage is impractical.\u003c\/p\u003e\n\n\u003cp\u003ePowered by a 0.9 kW motor, the pump delivers a maximum flow rate of 220 L\/min and reaches a maximum head of 16.5 m. Operating on a 415v supply, it draws a rated current of 2.3 Amps while the submerged motor supports continuous duty operation. The horizontal delivery port accommodates both DN 32 PN 6 flanged and G 1 1\/2 threaded pipework connections for installation flexibility.\u003c\/p\u003e\n\n\u003cp\u003eThe hydraulic system incorporates a patented grinding mechanism utilizing rotating and fixed cutting blades manufactured from hardened AISI 440C stainless steel. This configuration reduces paper, textile and long filamentary materials to a 6 mm solid passage, significantly reducing the risk of clogging in discharge systems. A cast iron open impeller provides dependable hydraulic performance for wastewater transfer from domestic collection pits.\u003c\/p\u003e\n\n\u003cp\u003eConstruction features a rugged GJL 200 cast iron pump casing and impeller for long-term durability in permanent submerged installations. Motor protection is provided by a double mechanical shaft seal with an interposed oil chamber containing oil suitable for food and pharmaceutical machinery. The AISI 304 stainless steel motor jacket and AISI 303 shaft are complemented by a triple impregnation humidity-proof dry winding for reliable service.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePatented grinding system with hardened AISI 440C rotating and fixed cutting blades for efficient wastewater maceration.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty GJL 200 cast iron pump casing and impeller provide excellent durability for domestic sewage applications.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with an intermediate oil chamber protects the motor against water ingress.\u003c\/li\u003e\n\u003cli\u003eHorizontal delivery port supports both DN 32 PN 6 flanged and G 1 1\/2 threaded discharge connections.\u003c\/li\u003e\n\u003cli\u003eChrome-nickel stainless steel AISI 304 motor jacket and AISI 303 shaft provide excellent corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eTriple impregnation humidity-proof dry winding supports dependable submerged motor operation.\u003c\/li\u003e\n\u003cli\u003eIP X8 protection rating allows permanent immersion up to 5 m depth.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10 m power cable for fixed installation in domestic wastewater collection pits.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50915186475255,"sku":"GQG 6-18","price":1736.55,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-gqg-6-18-cast-iron-high-power-submersible-grinder-pump-for-domestic-sewage-with-grinding-system.png?v=1783163826","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-gqg-6-18-cast-iron-high-power-submersible-grinder-pump-for-domestic-sewage-with-grinding-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
