Electrode-controlled operation automatically manages start and stop cycles based on water level contact, eliminating dry-running and excessive mechanical stress while reducing power consumption. This mechanism ensures reliable performance in the most demanding automatic drainage applications.\u003c\/p\u003e\u003cp\u003eDriven by a 3.7 kW \/ 415v motor, the system offers up to approximately 18 m of head and up to approximately 1440 L\/Min flow through its 100 mm bore. The combination provides consistent volume displacement and stable vertical lift for automatic quarry drainage. The 2-pole induction motor handles drainage fluids with up to 10% dry matter content and operates reliably across a wide pH range of 5 to 9.\u003c\/p\u003e\u003cp\u003ePumping performance is supported by a high-chromium cast iron semi-open impeller that resists the erosive impact of high-velocity abrasive particles. The pump maintains smooth movement for solids up to 8.5 mm, ensuring that site water is displaced effectively through the side flow housing. This design ensures that abrasive particles are carried through the pump with minimal casing impact, significantly extending the service life of the pump housing.\u003c\/p\u003e\u003cp\u003eDual inside silicon carbide mechanical seals and Tsurumi's original Oil Lifter provide stable shaft sealing. A gray cast iron body and top discharge design enable efficient motor cooling. An anti-wicking cable entry block and circle thermal protector built into the motor housing guard against moisture and thermal stress. For harsh sites, an optional structural steel probe cover is available.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrated electrode control relay enables energy-saving automatic operation and reduces power costs by 40%.\u003c\/li\u003e\n\u003cli\u003eHigh-capacity 1440 L\/Min flow rate enables rapid automatic displacement of site water in large-scale quarries.\u003c\/li\u003e\n\u003cli\u003eDry-running prevention proactively extends pump service life by eliminating the stress of air-pumping.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium iron semi-open impeller provides superior resistance to erosion in abrasive sand-laden water.\u003c\/li\u003e\n\u003cli\u003eTop discharge, side flow cooling design facilitates continuous duty during drawdown by cooling the housing.\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 lubrication down to one-third of the normal oil level for sustained sealing effect.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable block protects the motor from moisture ingress through the electrical cable sheaths.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50933812166903,"sku":"KTZE43.7","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktze43-7-cast-iron-automatic-submersible-drainage-pump-for-quarry-dewatering-with-semi-open-impeller.png?v=1783914263","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktze43-7-cast-iron-automatic-submersible-drainage-pump-for-quarry-dewatering-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
