This high-output submersible pump excels in moving large quantities of sand-carrying water from excavated sites where rapid displacement is a primary logistical requirement. The robust cast iron frame and 150 mm discharge are engineered for continuous service in demanding civil engineering environments.\u003c\/p\u003e\u003cp\u003eDriven by a 7.5 kW \/ 415v motor, the unit is capable of up to approximately 2030 L\/Min flow and up to approximately 31 m of head. This performance is optimized for high-volume transfer through its large-bore 150 mm discharge system, providing stable circulation behavior during long-term site water control. The 2-pole motor operates reliably in drainage fluids containing up to 10% dry matter with a pH between 5 and 9.\u003c\/p\u003e\u003cp\u003eWear resistance comes from a high-chromium cast iron semi-open impeller designed to resist the erosive impact of high-velocity abrasive particles. It maintains smooth throughput for solids up to 20 mm, ensuring site debris does not accumulate within the housing or cause performance drop-off. Streamlining the internal flow path protects the cast iron housing from localized wear during large-scale floodwater removal cycles.\u003c\/p\u003e\u003cp\u003eDual inside mechanical seals with silicon carbide faces are isolated in an oil chamber featuring Tsurumi's patented Oil Lifter. A top discharge design and side flow cooling mechanism ensure effective motor heat dissipation. Protection features include an anti-wicking cable entry block and a circle thermal protector built into the 7.5 kW motor housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLarge 150 mm discharge bore facilitates the high-volume movement of 2030 L\/Min for rapid site dewatering.\u003c\/li\u003e\n\u003cli\u003eHigh-chromium iron semi-open impeller provides exceptional resistance to erosive wear in abrasive site duty.\u003c\/li\u003e\n\u003cli\u003eIntegrated seal pressure relief ports protect mechanical seals by diverting high internal hydraulic stress.\u003c\/li\u003e\n\u003cli\u003eTop discharge, side flow configuration enables reliable continuous duty even during partially exposed operation.\u003c\/li\u003e\n\u003cli\u003eDual silicon carbide mechanical seals provide ultimate protection against dry-heating and chemical corrosion.\u003c\/li\u003e\n\u003cli\u003eLabyrinth ring made of 304 stainless steel provides a countermeasure against wear caused by high internal pressure.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry proactively guards against motor damage from capillary water incursion or moisture.\u003c\/li\u003e\n\u003cli\u003eBuilt-in circle thermal protector proactively monitors motor temperature and interrupts the circuit during overload.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50931154256119,"sku":"KTZ67.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktz67-5-cast-iron-high-capacity-drainage-pump-for-stormwater-management-with-semi-open-impeller.png?v=1783765211","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktz67-5-cast-iron-high-capacity-drainage-pump-for-stormwater-management-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
