This extra-high-power submersible pump provides unmatched displacement for these applications, where reliability is the primary logistical requirement. The robust flagship design is built for continuous, heavy-duty operation in the world's most challenging mining and construction environments.\u003c\/p\u003e\u003cp\u003ePowered by a massive 22 kW \/ 415v motor, the unit achieves up to approximately 55 m of head and up to approximately 4000 L\/Min flow. This output provides extreme throughput through its large-bore 150 mm discharge system, ensuring site safety during the most demanding discharge cycles. The unit maintains stable operating behavior while handling fluids with up to 10% dry matter content.\u003c\/p\u003e\u003cp\u003eWear resistance comes from a high-chromium cast iron semi-open impeller and a 304 stainless steel labyrinth ring to resist high-pressure internal wear. The pump maintains smooth movement for solids up to 12 mm, ensuring site water is displaced effectively through the side flow casing. To protect the mechanical seal, the pump incorporates specialized pressure relief ports that divert extreme internal hydraulic force away from the faces.\u003c\/p\u003e\u003cp\u003eDuplex angular contact ball bearings and a cooling path that facilitates heat dissipation during exposed operation 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 industrial electrical networks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIncredible 4000 L\/Min throughput enables rapid displacement of site water in large-scale dewatering projects.\u003c\/li\u003e\n\u003cli\u003ePowerful 55 m vertical lift capability makes this model suitable for the deepest excavations and mine sumps.\u003c\/li\u003e\n\u003cli\u003eSeal pressure relief ports proactively extend mechanical seal life by diverting high internal hydraulic force.\u003c\/li\u003e\n\u003cli\u003eMiniature thermal protectors (MTP) embedded in motor windings provide ultimate detection of overheating.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium cast iron semi-open impeller provides extreme resistance to the erosive impact of solids.\u003c\/li\u003e\n\u003cli\u003e304 stainless steel labyrinth ring provides a countermeasure against wear caused by high internal pressure.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry with an anti-wicking block protects the motor from internal moisture and condensation.\u003c\/li\u003e\n\u003cli\u003eDual silicon carbide mechanical seals offer five times higher corrosion and heat resistance than tungsten carbide.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931154354423,"sku":"KTZ622","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktz622-cast-iron-mtp-protected-submersible-drainage-pump-for-large-scale-dewatering-with-semi-open-impeller.png?v=1783765216","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktz622-cast-iron-mtp-protected-submersible-drainage-pump-for-large-scale-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
