Electrode-controlled operation automatically starts and stops the unit to prevent dry-running and reduce power consumption by up to 40%. This mechanism contributes to a significantly longer operating life while maintaining safe site water levels.\u003c\/p\u003e\u003cp\u003eEquipped with a 3.7 kW \/ 415v three-phase motor, the system reaches up to approximately 36.5 m of head and up to approximately 450 L\/Min flow. This performance provides powerful vertical lift for automatic foundation drainage through a 50 mm discharge. The 2-pole motor operates reliably in drainage fluids containing up to 10% dry matter content within a wide pH range of 5 to 9.\u003c\/p\u003e\u003cp\u003eWear resistance comes from a high-chromium cast iron semi-open impeller designed to resist wear from abrasive particles in suspension. It maintains smooth movement for solids up to 8.5 mm, ensuring that sucked-up site debris is displaced through the housing without settling or causing performance drop-off. Streamlining the internal flow path protects the cast iron housing from localized wear during automatic discharge cycles.\u003c\/p\u003e\u003cp\u003eDual silicon carbide mechanical seals and a side flow cooling mechanism that transfers motor heat to the pumped media provide robust protection. A gray cast iron frame and anti-wicking cable entry block guard against moisture ingress. Optional accessories include a structural steel electrode probe cover to protect critical control components from impact in harsh environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInnovative automatic electrode relay eliminates the need for cumbersome floats and reduces power costs.\u003c\/li\u003e\n\u003cli\u003ePowerful 36.5 m vertical head makes this automatic model ideal for deep-site foundation dewatering.\u003c\/li\u003e\n\u003cli\u003eDry-running prevention mechanism proactively extends pump service life by eliminating air-pumping stress.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium iron semi-open impeller provides exceptional resistance to erosion in abrasive site drainage.\u003c\/li\u003e\n\u003cli\u003eTop discharge, side flow cooling design ensures reliability even when running in air-exposed conditions.\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\u003cli\u003ePatented Oil Lifter ensures seal face lubrication and cooling down to one-third of the normal volume.\u003c\/li\u003e\n\u003cli\u003eWatertight cable entry with an anti-wicking block protects the motor from capillary water incursion and condensation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50933811020023,"sku":"KTZE23.7","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktze23-7-cast-iron-automatic-submersible-drainage-pump-for-foundation-dewatering-with-semi-open-impeller.png?v=1783914258","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktze23-7-cast-iron-automatic-submersible-drainage-pump-for-foundation-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
