This auto-alternation submersible vortex pump is configured for coordinated dual-pump operation, ensuring reliable site dewatering without manual oversight. Its large 80 mm discharge and corrosion-resistant construction provide a robust technical solution for commercial sumps.\u003c\/p\u003e\u003cp\u003eOperating with a 1.5 kW \/ 415v three-phase motor, the unit achieves a peak flow of approximately 780 L\/Min and reaches a maximum head of approximately 15.2 m. The auto-alternation control system provides start and stop based on liquid level while facilitating duty-sharing. The motor is continuous-duty rated for stable performance in high-volume wastewater management and site drainage systems.\u003c\/p\u003e\u003cp\u003eThe hydraulic assembly features a high-flow vortex impeller that facilitates the passage of large solids up to 46 mm. This design creates a powerful whirlpool that moves debris through the pump casing with minimal impeller contact, preventing clogging and reducing mechanical wear caused by abrasive site particles. The practically unchokable arrangement is essential for handling solids-laden wastewater in coordinated industrial sumps.\u003c\/p\u003e\u003cp\u003eStructural integrity is provided by a resin and 304 stainless steel body, with a 304 stainless steel shaft for enhanced chemical compatibility. Sealing is ensured by a double-face mechanical seal located in an oil chamber with lower silicon carbide seal faces and a proprietary Oil Lifter. Protection is reinforced by an anti-wicking cable entry and a circle thermal protector that safeguards the motor from thermal and overcurrent conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAuto-alternation control facilitates duty-sharing dual-pump operation for coordinated wastewater management.\u003c\/li\u003e\n\u003cli\u003eLarge-passage vortex impeller allows for 46 mm solids handling, making the unit practically unchokable in sewage duty.\u003c\/li\u003e\n\u003cli\u003eResin and 304 stainless steel construction ensures superior durability and corrosion resistance in wastewater.\u003c\/li\u003e\n\u003cli\u003eHigh-volume 80 mm discharge bore achieves flow rates up to 780 L\/Min for rapid coordinated dewatering.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal located in an oil chamber with lower silicon carbide seal faces provides protection against abrasion and liquid ingress.\u003c\/li\u003e\n\u003cli\u003eTsurumi's patented Oil Lifter supplies lubricating oil to the seal faces even if the lubricant volume falls to low levels.\u003c\/li\u003e\n\u003cli\u003eCircle thermal protector built into the motor housing directly cuts the circuit during excessive heat buildup or overcurrent.\u003c\/li\u003e\n\u003cli\u003eOptional guide rail fitting system allows for safe maintenance and inspection without the need to enter the coordinated sump.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50938966114551,"sku":"80PUW21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80puw21-5-stainless-steel-auto-alternation-submersible-pump-for-wastewater-drainage-with-vortex-impeller.png?v=1784087682","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80puw21-5-stainless-steel-auto-alternation-submersible-pump-for-wastewater-drainage-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
