Rated at 3.7 kW with an 80 mm discharge bore, this three-phase model features a vortex impeller made of glass-fiber reinforced PA+ABS providing practically unchokable operation in sewage pumping. The pump is constructed from resin and 304 stainless steel, offering excellent corrosion-resistance. Liquid paraffin is used as the lubricating oil, making it safe for use in fishponds, aquaculture, and other water-sensitive applications. This auto-alternation model is designed for use in pairs with an automatic model, automatically alternating pump operation to share workload and provide redundancy. It is equipped with a float switch for automatic start\/stop operation, a circle thermal protector built into the motor housing, dual mechanical seals (Upper: Ceramic + Carbon, Lower: SiC + SiC) with an oil lifter, and an anti-wicking cable entry system. With a solids passage of 46 mm, the discharge connection is a threaded oval flange. This 50 Hz unit delivers dependable automatic wastewater transfer for critical applications. \u003c\/p\u003e\u003ch3\u003eSuitable Applications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eEqualization tanks\u003c\/li\u003e \u003cli\u003eWastewater measuring tanks\u003c\/li\u003e \u003cli\u003eSeptic tanks and sewage treatment plants\u003c\/li\u003e \u003cli\u003eConstruction wastewater drainage\u003c\/li\u003e \u003cli\u003eWater transfer\u003c\/li\u003e \u003cli\u003eWaterscapes, ponds, aquariums, and fish farms\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e \u003ctable class=\"spec-table\"\u003e \u003ctr\u003e \u003ctd\u003eProduct Name\u003c\/td\u003e \u003ctd\u003eTsurumi 80PUW23.7\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eProduct Number\u003c\/td\u003e \u003ctd\u003e80PUW23.7\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePump Type\u003c\/td\u003e \u003ctd\u003eAuto-Alternation Submersible Vortex Sewage Pump\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDischarge Bore\u003c\/td\u003e \u003ctd\u003e80 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eConnection\u003c\/td\u003e \u003ctd\u003eThreaded Oval Flange\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMotor Power (P2)\u003c\/td\u003e \u003ctd\u003e3.7 kW\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePhase\u003c\/td\u003e \u003ctd\u003eThree-phase\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSpeed\u003c\/td\u003e \u003ctd\u003e3000 min⁻¹ (50 Hz)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eStarting Method\u003c\/td\u003e \u003ctd\u003eDirect on Line (D.O.L.) with Float Switch\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eSolids Passage\u003c\/td\u003e \u003ctd\u003e46 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eImpeller Material\u003c\/td\u003e \u003ctd\u003eGlass-fiber reinforced PA+ABS (vortex)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShaft Material\u003c\/td\u003e \u003ctd\u003e304 stainless steel\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShaft Seal\u003c\/td\u003e \u003ctd\u003eDual mechanical seal (Upper: Ceramic + Carbon, Lower: SiC + SiC) with oil lifter\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLubricating Oil\u003c\/td\u003e \u003ctd\u003eLiquid Paraffin (ISO VG32), 680 ml\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMotor Protection\u003c\/td\u003e \u003ctd\u003eCircle thermal protector (built in motor housing)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eInsulation Class\u003c\/td\u003e \u003ctd\u003eE\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eEnclosure Class\u003c\/td\u003e \u003ctd\u003eIP68\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eVoltage\u003c\/td\u003e \u003ctd\u003e380-415 V\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFrequency\u003c\/td\u003e \u003ctd\u003e50 Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eRated Current\u003c\/td\u003e \u003ctd\u003e7.5 – 7.9 A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePower Cable\u003c\/td\u003e \u003ctd\u003ePVC sheath, 1 × 4 × 2.0mm², O.D. 11.8mm, Length: 6m\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLiquid Temperature Range\u003c\/td\u003e \u003ctd\u003e0 to 40°C\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDry Weight (excluding cable)\u003c\/td\u003e \u003ctd\u003e28.0 kg\u003c\/td\u003e \u003c\/tr\u003e \u003c\/table\u003e\u003ch3\u003eDocumentation \u0026amp; Downloads\u003c\/h3\u003e \u003ctable class=\"pdf-table\"\u003e \u003ctr\u003e \u003ctd\u003eVANCS PU \/ PN \/ TM Series Specification\u003c\/td\u003e \u003ctd\u003e\u003ca href=\"https:\/\/tsurumipumps.com.au\/wp-content\/uploads\/2022\/11\/VANCS-PU_PN_TM_IS122-A-AUS-SPEC-1.pdf\" target=\"_blank\"\u003eDownload\u003c\/a\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePU Series Product Guide\u003c\/td\u003e \u003ctd\u003e\u003ca href=\"https:\/\/tsurumipumps.com.au\/wp-content\/uploads\/2024\/01\/PU-Product-Guide-24.01.pdf\" target=\"_blank\"\u003eDownload\u003c\/a\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003c\/table\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":45489008738413,"sku":"40PN2.25S","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1399\/2979\/files\/PN.png?v=1784788336","url":"https:\/\/pumptastic.com.au\/products\/tsurumi-40pn2-25s-submersible-portable-sewage-wastewater-pump-40pn2-25s","provider":"Pumptastic","version":"1.0","type":"link"}
