This auto-alternation submersible vortex pump is configured with automatic operation for duty-sharing, ensuring redundant site water management in factory and industrial tanks. Its specialized resin and stainless steel construction provides outstanding durability in corrosive conditions where equipment longevity is a priority.\u003c\/p\u003e\u003cp\u003eDriven by a 0.4 kW \/ 415v three-phase motor, the unit achieves a maximum flow of approximately 270 L\/Min and a peak head of approximately 9.6 m. The auto-alternation system facilitates dual-pump coordination, providing start and stop based on liquid level. The motor is continuous-duty rated, ensuring stable performance during intensive dewatering cycles in coordinated wastewater sumps.\u003c\/p\u003e\u003cp\u003eThe unit features a recessed vortex impeller that enables 35 mm solids passage, ensuring that suspended particles move through the pump casing with minimal contact between solids and the impeller. This hydraulic arrangement is ideal for liquids bearing organic matter, as the recessed design prevents debris from obstructing the flow path. This configuration maintains operational efficiency while resisting the erosive effects typical of solids-bearing wastewater.\u003c\/p\u003e\u003cp\u003eStructural integrity is maintained through a resin and 304 stainless steel frame, with a double-face mechanical seal located in an oil chamber for superior sealing. Protection is provided by an internal circle thermal protector and an anti-wicking cable entry that shields the motor from moisture. The use of non-toxic liquid paraffin as a lubricant makes the pump suitable for applications where liquid contamination is undesirable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAuto-alternation functionality allows for duty-sharing dual-pump operation in tank drainage.\u003c\/li\u003e\n\u003cli\u003eGlass-fiber reinforced resin and 304 stainless steel build ensures outstanding corrosion resistance for industrial wastewater duty.\u003c\/li\u003e\n\u003cli\u003eRecessed vortex impeller facilitates the displacement of 35 mm solids while reducing mechanical contact and hydraulic wear.\u003c\/li\u003e\n\u003cli\u003eLiquid paraffin is used as the lubricant, making the pump suitable for sensitive liquid transfer applications.\u003c\/li\u003e\n\u003cli\u003eTsurumi's original Oil Lifter supplies lubricating oil to the seal faces even at low oil volumes.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal operating in an oil chamber offers high resistance to thermal stress and abrasive chemical attack.\u003c\/li\u003e\n\u003cli\u003eInternal circle thermal protector directly cuts the motor circuit if excessive heat builds up or an overcurrent occurs.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry with an anti-wicking block protects the motor from moisture incursion even if the cable is submerged.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50938966049015,"sku":"50PUW2.4","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-50puw2-4-stainless-steel-auto-alternation-submersible-pump-for-effluent-transfer-with-vortex-impeller.png?v=1784087679","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-50puw2-4-stainless-steel-auto-alternation-submersible-pump-for-effluent-transfer-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
