The Tsurumi NKZ43.7 is specifically designed to aggressively agitate and evacuate these heavy sediment loads, preventing operational bottlenecks. Its rugged construction ensures reliable performance in the harshest mineral processing environments.\u003c\/p\u003e\n\u003cp\u003eOperating on a 415 V three-phase supply, this unit features a 3.7 kW, 4-pole motor drawing 8.4 Amps. It delivers a maximum flow rate of 1500 L\/Min and a maximum head of 16.5 m. The 4-pole motor configuration is crucial here, as its lower rotational speed significantly mitigates the erosive wear caused by pumping abrasive stone dust and grit.\u003c\/p\u003e\n\u003cp\u003eThe intake process is supercharged by a ductile cast iron agitator that fluidizes settled quarry sludge, feeding it into the ductile cast iron semi-open impeller. With a 30mm solids passage and a larger 100mm discharge, this pump effortlessly moves high volumes of thick, rocky slurry through its side discharge spiral casing without clogging.\u003c\/p\u003e\n\u003cp\u003eThe 104 kg cast iron pump body is built to survive extreme conditions. It features a built-in water jacket that circulates fluid around the motor, guaranteeing efficient cooling even when the water level drops below the motor housing. Dual inside mechanical seals and a Circle Thermal Protector provide comprehensive defense against mechanical and electrical failures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e Facilitates the rapid evacuation of high-volume slurries and 30mm solids, preventing bottlenecks in the casing.\u003c\/li\u003e\n\u003cli\u003e Vigorously churns settled rock dust and sludge into a pumpable fluid, ensuring continuous, jam-free operation.\u003c\/li\u003e\n\u003cli\u003e Routes discharged water around the motor frame, allowing the pump to run safely even when partially exposed to air.\u003c\/li\u003e\n\u003cli\u003e Delivers high torque at lower speeds, dramatically reducing the internal wear caused by abrasive quarry fluids.\u003c\/li\u003e\n\u003cli\u003e Continuously supplies lubricating oil to the upper and lower seal faces, maintaining a perfect seal under severe conditions.\u003c\/li\u003e\n\u003cli\u003e Provides a straightforward, reliable starting mechanism, backed by an integrated thermal protector to prevent motor burnout.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50934168158455,"sku":"NKZ43.7","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-nkz43-7-cast-iron-rugged-build-submersible-slurry-pump-for-quarries-with-semi-open-impeller.png?v=1783937874","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-nkz43-7-cast-iron-rugged-build-submersible-slurry-pump-for-quarries-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
