It is intended for permanent submerged installation in collection pits where wastewater must be macerated before discharge through small-diameter pipework. The unit operates with liquid temperatures up to 35°C in fixed vertical installations.\u003c\/p\u003e\n\n\u003cp\u003eThe 1.1 kW motor delivers a maximum flow rate of 250 L\/min and reaches a maximum head of 19.2 m. Operating on a 415v supply, it draws a rated current of 2.8 Amps while the submerged motor is designed for continuous duty operation. The horizontal delivery outlet accommodates both DN 32 PN 6 flanged and G 1 1\/2 threaded pipe connections to simplify installation.\u003c\/p\u003e\n\n\u003cp\u003eWastewater is processed through a patented grinding mechanism using hardened AISI 440C rotating and fixed cutting blades that reduce paper, textile and long filamentary materials to a 6 mm solid passage. Combined with a cast iron open impeller, this hydraulic arrangement delivers reliable wastewater transfer while reducing the likelihood of discharge line blockages.\u003c\/p\u003e\n\n\u003cp\u003eThe pump body is manufactured from GJL 200 cast iron for excellent structural strength in permanent submerged service. A double mechanical shaft seal with an intermediate oil chamber protects the motor against water ingress, while the AISI 304 stainless steel motor jacket, AISI 303 shaft and triple impregnation humidity-proof winding provide long-term durability in demanding wastewater applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePatented AISI 440C grinding system efficiently macerates paper, textile and filamentary wastewater solids.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty GJL 200 cast iron pump casing and impeller deliver long service life in civil sewage applications.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with an intermediate oil chamber protects the motor during continuous submerged operation.\u003c\/li\u003e\n\u003cli\u003eHorizontal outlet supports both DN 32 PN 6 flanged and G 1 1\/2 threaded discharge pipe connections.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel motor jacket and AISI 303 shaft provide high corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eTriple impregnation humidity-proof dry winding improves electrical reliability in submerged installations.\u003c\/li\u003e\n\u003cli\u003eIP X8 protection rating permits permanent immersion up to 5 m depth.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 10 m power cable for fixed installation in wastewater collection systems.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50915186508023,"sku":"GQG 6-21","price":1951.65,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-gqg-6-21-cast-iron-high-power-submersible-grinder-pump-for-residential-wastewater-with-grinding-system.png?v=1783163828","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-gqg-6-21-cast-iron-high-power-submersible-grinder-pump-for-residential-wastewater-with-grinding-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
