Its 316 stainless steel casting construction provides outstanding corrosion resistance in harsh environments where standard materials would fail. The unit is a practical solution for transferring wastewater and site runoff in mining, aggregate, and industrial fields.\u003c\/p\u003e\u003cp\u003eDriven by a 1.5 kW \/ 415v motor, the pumping system achieves a maximum head of approximately 21 m and provides a flow capacity of approximately 645 L\/Min. This 3-phase induction motor is continuous-duty rated for stable site water management through an 80 mm discharge bore. It handles drainage water with up to 10% dry matter and maintains reliable discharge pressure during drawdown.\u003c\/p\u003e\u003cp\u003eThe hydraulic design features a semi-open multi-vane impeller made of 316 stainless steel casting to facilitate the passage of solids up to 6 mm. This impeller configuration is dynamically balanced to reduce mechanical wear during high-head duties. The flow path assists the movement of abrasive particles through the pump casing, resisting erosive wear from corrosive site liquids and aggressive sewage.\u003c\/p\u003e\u003cp\u003eMechanical integrity is supported by a double-face mechanical seal with silicon carbide faces isolated in an oil chamber featuring an Oil Lifter. Protection is enhanced by FKM rubber parts and a circle thermal protector built into the motor housing. The unit utilizes a watertight cable entry with an anti-wicking block to protect the motor from moisture incursion, ensuring durability in demanding industrial sumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSCS14 (316 stainless steel casting) construction provides excellent corrosion resistance for handling aggressive sewage and wastewater.\u003c\/li\u003e\n\u003cli\u003eDynamically balanced semi-open multi-vane impeller facilitates the displacement of solids up to 6 mm during drainage cycles.\u003c\/li\u003e\n\u003cli\u003eSilicon carbide faces on both upper and lower mechanical seals offer high durability against abrasion and chemical erosion.\u003c\/li\u003e\n\u003cli\u003eProprietary Oil Lifter provides lubrication to the upper seal faces even if the lubricant volume falls to one-third of the rated level.\u003c\/li\u003e\n\u003cli\u003eChemical-resistant FKM (FPM) rubber parts ensure longevity when the unit is exposed to acidic or aggressive industrial liquids.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry block protects the motor from capillary water incursion should the cable be damaged or submerged.\u003c\/li\u003e\n\u003cli\u003eCircle thermal protector in the motor housing directly interrupts the circuit during thermal stress or electrical overload.\u003c\/li\u003e\n\u003cli\u003e80 mm discharge bore and 1.5 kW motor provide stable hydraulic performance for industrial dewatering and site water management.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50937165316343,"sku":"80SFQ21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-80sfq21-5-submersible-corrosion-resistant-pump-for-mine-dewatering-with-semi-open-impeller.png?v=1784023198","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-80sfq21-5-submersible-corrosion-resistant-pump-for-mine-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
