It is delivered with a 10 m standard power cable to support deep installations and simplify maintenance in remote field operations.\u003c\/p\u003e\n\u003cp\u003eSpecially engineered for demanding and harsh industrial environments, the Tsurumi LH422 is suited for Deep Well Dewatering where heavy-duty water displacement is critical. 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\u003eThe pump is equipped with a high-chromium cast iron Closed impeller that handles solid particles up to 6 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\u003eOn a three-phase power supply, this model exhibits superior hydraulic capability, running on a motor output of 22 kW \/ 415v. It is designed to pump up to a maximum flow rate of 2300 L\/Min and is capable of reaching a maximum total head of 66 m, providing stable fluid movement throughout its service cycle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAnti-wicking cable entry system halts water ingress due to capillary action should the outer cable sheath suffer mechanical damage.\u003c\/li\u003e\n  \u003cli\u003eDual inside mechanical seals with silicon carbide faces reside in an oil chamber, providing five times higher wear resistance than tungsten carbide.\u003c\/li\u003e\n  \u003cli\u003eGalvanic anodes shield the cast iron pump body against corrosive potential generated during wastewater drainage operations.\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\u003eHeavy-duty cable clip guards the power line against rough handling and accidental tension on busy industrial construction sites.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931158515959,"sku":"LH422","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-lh422-cast-iron-heavy-duty-submersible-drainage-pump-for-mine-pit-drainage-with-closed-impeller.png?v=1783765652","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-lh422-cast-iron-heavy-duty-submersible-drainage-pump-for-mine-pit-drainage-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
