It handles sand-carrying water and foundation dewatering runoff over elevations where standard drainage pumps typically struggle. The robust mechanical construction and slim profile facilitate installation in restricted foundation pits while withstanding harsh site conditions.\u003c\/p\u003e\u003cp\u003eMaximum performance reaches 33.8 m of head, with a flow capacity of approx 500 L\/Min, driven by a 3.7 kW \/ 415v dry-type induction motor. This output is delivered through a 50 mm discharge, providing the pressure necessary for effective water removal from deep excavations. The motor maintains stable operation across a pH range of 5 to 9 and handles water containing up to 10% dry matter without performance degradation.\u003c\/p\u003e\u003cp\u003eA ductile cast iron vortex impeller with high-gap geometry forms the core of the hydraulic system, capable of passing solids up to 8.5 mm. This configuration is specifically suited to high-head applications where abrasive particles are entrained in the pumped fluid. The impeller design promotes efficient solids movement while resisting the erosive effects of sand and debris common in deep excavation sites.\u003c\/p\u003e\u003cp\u003eCooling efficiency is ensured by the top-discharge, side-flow design, which maintains motor temperature even when the pump operates partially exposed to air. A double-face mechanical seal with silicon carbide faces is protected by an oil chamber incorporating the Oil Lifter system. An anti-wicking cable entry and circle thermal protector provide additional motor safeguards, while the 304 stainless steel protection plate shields the aluminium casing from abrasive particles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-head hydraulic design achieves vertical lift up to 33.8 m for deep excavations and site dewatering tasks.\u003c\/li\u003e\n\u003cli\u003eDuctile cast iron vortex impeller with high-gap geometry facilitates the passage of solids up to 8.5 mm.\u003c\/li\u003e\n\u003cli\u003eTop-discharge, side-flow design provides efficient motor cooling even when the motor is exposed to air during drawdown cycles.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal with silicon carbide faces provides superior resistance to abrasion compared to standard ceramic faces.\u003c\/li\u003e\n\u003cli\u003eProprietary Oil Lifter maintains consistent lubrication of the mechanical seal faces even if lubricant falls below rated levels.\u003c\/li\u003e\n\u003cli\u003e304 stainless steel protection plate shields the internal alloy casing components from abrasive particles.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry block protects the motor from capillary water incursion should the power cable be damaged.\u003c\/li\u003e\n\u003cli\u003eDie-casted aluminium alloy body significantly reduces overall weight to simplify pump retrieval and relocation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50934166290679,"sku":"KTV2-37H","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktv2-37h-aluminium-alloy-high-head-submersible-drainage-pump-for-deep-excavations-with-vortex-impeller.png?v=1783937820","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktv2-37h-aluminium-alloy-high-head-submersible-drainage-pump-for-deep-excavations-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
