This heavy-duty 4-pole pump operates in municipal sewage treatment facilities, deep drainage basins, and industrial lift stations. It transfers unscreened raw sewage, thick municipal sludge, and heavy factory wastewater.\u003c\/p\u003e\n\u003cp\u003eThe unit features an 11 kW Three-phase induction motor operating on a 415 V electrical supply. It starts via the star-delta method and draws high starting currents. Operating at 1500 rpm, the hydraulic system achieves a maximum head of Approximately 22.8 m and a maximum flow rate of Approximately 1800 L\/Min.\u003c\/p\u003e\n\u003cp\u003eA recessed vortex impeller made of dynamically balanced cast iron is paired with a widely opened volute casing. The design provides an 80mm solids passage, enabling large solid matters to pass through the pump casing with minimal impeller contact. This centrifugal flow prevents long fibers from wrapping around the impeller or shaft.\u003c\/p\u003e\n\u003cp\u003eThe physical structure consists of a robust cast iron body, high-tensile stainless steel shaft, and C3 ball bearings. Sealing is managed by a double-face mechanical seal with silicon carbide faces in an oil chamber. Built-in miniature thermal protectors embedded in the windings protect the motor from thermal damage. It operates up to 40°C and supports TOS guide rails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-quality C3 double-shielded bearings support radial and axial loads.\u003c\/li\u003e\n\u003cli\u003eResides in oil chamber with silicon carbide faces to resist abrasive wear.\u003c\/li\u003e\n\u003cli\u003eIntegrated protector directly cuts the circuit during thermal overload.\u003c\/li\u003e\n\u003cli\u003eMolded rubber barrier prevents capillary water ingress from damaged cables.\u003c\/li\u003e\n\u003cli\u003eForcibly supplies turbine oil to the shaft seal, preventing dry-running damage and extending shaft seal service life.\u003c\/li\u003e\n\u003cli\u003eStainless steel shaft transmits full-load motor torque with high rigidity.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50947172499703,"sku":"80UZ411","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80uz411-cast-iron-star-delta-submersible-sewage-pump-for-municipal-projects-with-vortex-impeller.png?v=1784275767","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80uz411-cast-iron-star-delta-submersible-sewage-pump-for-municipal-projects-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
