This submersible pump excels in moving abrasive sand-carrying water and stormwater from deep excavations where system reliability is critical to progress. The flagship design ensures high-head performance while maintaining a slim footprint for easier placement in restricted foundation pits.\u003c\/p\u003e\u003cp\u003ePowered by a 5.5 kW \/ 415v motor, the unit generates up to approximately 32 m of head and up to approximately 1100 L\/Min flow through its 80 mm bore. This output supports the lift required for high-elevation transfer and deep site water control. The 2-pole dry-type induction motor handles drainage water with up to 10% dry matter across a wide pH range of 5 to 9.\u003c\/p\u003e\u003cp\u003eHydraulic efficiency is maintained by a high-chromium cast iron semi-open impeller designed to resist the erosive wear caused by abrasive site debris. It facilitates the movement of solids up to 8.5 mm, ensuring that site water is displaced effectively through the side flow casing. This design ensures that abrasive particles are carried through the pump with minimal housing impact, significantly extending the service life of the pump housing.\u003c\/p\u003e\u003cp\u003eDual inside silicon carbide mechanical seals and Tsurumi's patented Oil Lifter provide stable shaft sealing. A gray cast iron body and top discharge design ensure efficient motor cooling during partially exposed operation. Protection features include an anti-wicking cable entry and a circle thermal protector to guard against moisture and thermal stress.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePowerful 5.5 kW motor delivers 32 m maximum vertical lift for demanding high-head dewatering tasks.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium cast iron semi-open impeller provides extreme erosion resistance in abrasive drainage duty.\u003c\/li\u003e\n\u003cli\u003eSide flow cooling path enables continuous operation in air-exposed conditions by dissipating heat to the liquid.\u003c\/li\u003e\n\u003cli\u003eDual silicon carbide mechanical seals isolated in an oil chamber provide ultimate protection against dry-heating.\u003c\/li\u003e\n\u003cli\u003ePatented Oil Lifter ensures seal face lubrication even if the lubricant level falls below the rated volume.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry with an anti-wicking block protects the motor from internal condensation and moisture.\u003c\/li\u003e\n\u003cli\u003eBuilt-in circle thermal protector proactively monitors motor temperature to prevent thermal damage.\u003c\/li\u003e\n\u003cli\u003eOptional high-temperature liquid version allows for the management of aggressive media up to 80°C.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931154026743,"sku":"KTZ35.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktz35-5-cast-iron-high-head-drainage-pump-for-deep-excavation-dewatering-with-semi-open-impeller.png?v=1783765201","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktz35-5-cast-iron-high-head-drainage-pump-for-deep-excavation-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
