This submersible unit operates continuously even in highly challenging physical setups, making it a dependable choice for deep well, mine, or civil engineering worksites.\u003c\/p\u003e\n\u003cp\u003eOn a three-phase power supply, this model exhibits superior hydraulic capability, running on a motor output of 90 kW \/ 415v. It is designed to pump up to a maximum flow rate of 2500 L\/Min and is capable of reaching a maximum total head of 150 m, providing stable fluid movement throughout its service cycle.\u003c\/p\u003e\n\u003cp\u003eThe pump is equipped with a high-chromium cast iron Closed impeller that handles solid particles up to 10 mm in diameter without clogging. Its hydraulic flow passage is structurally optimized to manage abrasive materials and suspended sediments in muddy water, preventing wear during heavy-duty transfer operations.\u003c\/p\u003e\n\u003cp\u003eHoused in a rugged casing measuring 592 x 1787 mm and weighing 1,100 kg without cables, this cylindrical, slimline pump fits easily into narrow well casings. It is delivered with a 20 m standard power cable to support deep installations and simplify maintenance in remote field operations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTsurumi's exclusive oil lifter device maintains lubrication and cooling of the mechanical seal faces down to one-third of the normal oil level.\u003c\/li\u003e\n\u003cli\u003eTop discharge, flow-thru design forcibly cools the motor with the pumped liquid, allowing continuous low-water level operations.\u003c\/li\u003e\n\u003cli\u003eLabyrinth ring design counteracts high pressure wear within the casing, significantly improving overall maintainability in the field.\u003c\/li\u003e\n\u003cli\u003eShaft quenching treatment enhances surface hardness of key contact parts, extending mechanical seal service life when pumping silty water.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief port shields the shaft seal by releasing excessive pump pressure during deep submergence operations.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors react to dry-run heat, sending warning signals to a control panel to safely shut down the power supply.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931158810871,"sku":"LH690","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-lh690-cast-iron-mine-pit-submersible-drainage-pump-for-industrial-water-transfer-with-closed-impeller.png?v=1783765669","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-lh690-cast-iron-mine-pit-submersible-drainage-pump-for-industrial-water-transfer-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
