This automatic submersible vortex pump is configured with automatic level control, ensuring reliable site drainage without the need for manual monitoring. Its large 80 mm discharge and corrosion-resistant construction provide a robust technical solution for heavy-duty industrial and municipal sumps.\u003c\/p\u003e\n\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 automatic control system provides start and stop based on liquid level, while the Direct on Line starting method ensures immediate response to rising water levels. The motor is continuous-duty rated for stable performance in high-volume wastewater management systems.\u003c\/p\u003e\n\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 automated industrial sumps.\u003c\/p\u003e\n\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\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic operation provides hands-free management of wastewater sumps and sewage transfer.\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 heavy wastewater.\u003c\/li\u003e\n\u003cli\u003eHigh-volume 80 mm discharge bore achieves flow rates up to 780 L\/Min for rapid dewatering tasks.\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 easy maintenance and inspection without the need to enter the sump.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50937166823671,"sku":"80PUA21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80pua21-5-stainless-steel-automatic-submersible-pump-for-wastewater-drainage-with-vortex-impeller.png?v=1784023234","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80pua21-5-stainless-steel-automatic-submersible-pump-for-wastewater-drainage-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
