The relay unit automatically starts and stops the pump based on water contact, preventing dry-running and reducing power consumption. This mechanism is particularly valuable for foundation works where maintaining a clear, dry site is critical to construction progress.\u003c\/p\u003e\u003cp\u003eThe hydraulic assembly incorporates a ductile cast iron vortex impeller with high-gap geometry, capable of passing solids up to 8.5 mm. The flow path promotes efficient movement of abrasive particles through the pump during automatic drainage cycles, while the wear-resistant construction maintains performance in sand-laden water. This combination of automatic control and durable hydraulics ensures reliable operation in challenging site conditions.\u003c\/p\u003e\u003cp\u003eOutput is supplied by a 1.5 kW \/ 415v motor, which delivers a flow capacity of up to 420 L\/Min and a maximum head of 20 m through a 50 mm discharge. These hydraulic characteristics provide stable pumping efficiency for automatic site drainage applications, with the motor capable of handling water containing up to 10% dry matter across a pH range of 5 to 9. The system maintains consistent performance throughout fluctuating water levels without operator intervention.\u003c\/p\u003e\u003cp\u003eAn oil chamber with a double-face mechanical seal and silicon carbide faces provides reliable sealing, supported by the Oil Lifter for consistent lubrication. The die-casted aluminium alloy body reduces weight for easy deployment, while the top-discharge, side-flow design ensures effective motor cooling during operation. Protection is provided by an anti-wicking cable entry block and a circle thermal protector integrated into the motor housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eElectrode control relay enables automatic operation and reduces power consumption by automatically preventing dry-running.\u003c\/li\u003e\n\u003cli\u003eAutomatic dry-run prevention extends the operating life by eliminating the stress associated with air-pumping.\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\u003eDie-casted aluminium alloy body significantly reduces overall weight to simplify retrieval and deployment.\u003c\/li\u003e\n\u003cli\u003eDouble-face mechanical seal with silicon carbide faces provides resistance to abrasion and thermal stress.\u003c\/li\u003e\n\u003cli\u003eProprietary Oil Lifter maintains consistent lubrication of the mechanical seal faces even at low oil volumes.\u003c\/li\u003e\n\u003cli\u003eTop-discharge, side-flow design provides efficient motor cooling even when the motor is exposed to air during drawdown.\u003c\/li\u003e\n\u003cli\u003eAnti-wicking cable entry block protects the motor from capillary moisture incursion should the power cable be damaged.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Tsurumi","offers":[{"title":"Default Title","offer_id":50934166454519,"sku":"KTVE21.5","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/tsurumi-ktve21-5-aluminium-alloy-automatic-submersible-drainage-pump-for-foundation-works-with-vortex-impeller.png?v=1783937826","url":"https:\/\/foundationpumps.com.au\/products\/tsurumi-ktve21-5-aluminium-alloy-automatic-submersible-drainage-pump-for-foundation-works-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
