This extra-high-power submersible drainage pump excels in moving abrasive media over exceptional vertical distances where site progress depends on maintaining a clear drawdown under heavy hydraulic loads. The flagship cast iron construction is designed for continuous duty in the roughest site conditions globally.\u003c\/p\u003e\u003cp\u003ePowered by a massive 22 kW \/ 415v three-phase motor, the unit delivers up to approximately 71 m of head and up to approximately 2750 L\/Min flow. This output provides extreme pressure behavior for high-elevation displacement through a 100 mm discharge bore. The system operates reliably in varied chemical environments within a pH range of 5 to 9 and handles fluids containing up to 10% dry matter.\u003c\/p\u003e\u003cp\u003eHydraulic efficiency is maintained by a high-chromium cast iron semi-open impeller and a 304 stainless steel labyrinth ring to resist erosive wear during high-head operation. The pump facilitates the movement of solids up to 8.5 mm while protecting the cast iron housing from localized wear typical of high-head abrasive duties. To protect the mechanical seal against excessive pressure, the design incorporates specialized seal pressure relief ports.\u003c\/p\u003e\u003cp\u003eDuplex angular contact ball bearings and a cooling path that transfers motor heat to the pumped media provide robust mechanical integrity. Protection features include an electrode-type leakage sensor in the oil chamber and miniature thermal protectors (MTP) embedded in each motor winding. This model is available in high-temperature variants and optional 1000V configurations to match specialized site infrastructure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eExtreme 71 m vertical lift capability is specifically tuned for deep-site drawdown and high-elevation transfer.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief ports proactively extend mechanical seal life by diverting extreme internal hydraulic force.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors (MTP) embedded in each winding provide ultimate early detection of overheating.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium iron semi-open impeller provides extreme erosion resistance in abrasive mining duty.\u003c\/li\u003e\n\u003cli\u003e304 stainless steel labyrinth ring provides a superior countermeasure against high-pressure generated in the casing.\u003c\/li\u003e\n\u003cli\u003eTop discharge, side flow cooling design facilitates safe operation during partially exposed site liquid levels.\u003c\/li\u003e\n\u003cli\u003eDual silicon carbide mechanical seals offer five times higher resistance to abrasion and heat than tungsten carbide.\u003c\/li\u003e\n\u003cli\u003eAvailable 1000V motor configurations provide essential compatibility with high-voltage industrial electrical networks.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931154223351,"sku":"KTZ422","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktz422-cast-iron-mtp-protected-submersible-drainage-pump-for-deep-mine-dewatering-with-semi-open-impeller.png?v=1783765210","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktz422-cast-iron-mtp-protected-submersible-drainage-pump-for-deep-mine-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
