This specific vortex pump handles residential sewage, heavy industrial effluents, and municipal stormwater run-off. It is installed in collection pits, equalization tanks, and lifting stations to transfer viscous liquids with suspended particulates.\u003c\/p\u003e\n\u003cp\u003eThe electrical specifications include a 1.5 kW Three-phase induction motor operating on 415 V. This dry-type squirrel-cage motor draws a rated current of 3.5 Amps. Under standard operating conditions, the pump achieves a maximum head of Approximately 16 m and reaches a peak discharge capacity of Approximately 600 L\/Min, maintaining efficient drainage under steady system loads.\u003c\/p\u003e\n\u003cp\u003eA dynamically balanced cast iron vortex impeller is recessed within the widely opened casing to create a swirling flow. The hydraulic design provides a 46mm solids passage, allowing suspended solids to pass without wrapping around the shaft. By keeping the solids away from the impeller vanes, the pump minimizes mechanical wear and maintains constant hydraulic performance.\u003c\/p\u003e\n\u003cp\u003eConstruction materials consist of a heavy cast iron pump housing and a rigid 420 stainless steel shaft. Its sealing arrangement includes a double mechanical seal with silicon carbide lower faces in a turbine oil chamber.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStainless steel shaft resists rotational fatigue and mechanical stresses.\u003c\/li\u003e\n\u003cli\u003eBuilt-in thermal protector directly cuts the circuit during overcurrent.\u003c\/li\u003e\n\u003cli\u003eForcibly supplies turbine oil to seal faces, ensuring cooling even if oil volume drops, preventing dry run mechanical seal failure.\u003c\/li\u003e\n\u003cli\u003eDouble-shielded bearings support continuous shaft loads and smooth rotation.\u003c\/li\u003e\n\u003cli\u003eWatertight entry prevents capillary water ingress into the motor conductors.\u003c\/li\u003e\n\u003cli\u003eRecessed design creates a whirlpool flow to handle sewage without clogging or winding of fibrous materials.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50947169911031,"sku":"80U21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80u21-5-cast-iron-solid-handling-submersible-sewage-pump-for-wastewater-drainage-with-vortex-impeller.png?v=1784275737","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80u21-5-cast-iron-solid-handling-submersible-sewage-pump-for-wastewater-drainage-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
