Built for these conditions, the Unilift KP.250.AV.1 operates as a submersible drainage pump designed for clean water drainage, storm water handling and grey water applications. Its compact vertical float arrangement allows automatic operation where conventional float switches may have limited movement, making it suitable for domestic drainage and light industrial water transfer duties.\u003c\/p\u003e\n\n\u003cp\u003ePowered by a 0.25 kW (P2) motor operating on a standard 240V power supply, the unit functions with a rated current draw of 2.2 Amps. Designed to handle increased drainage capacity, the system delivers a maximum flow rate of 187 L\/Min through its 1¼ inch discharge connection. The hydraulic design also generates a maximum head of 7.5 metres, providing reliable vertical lift performance across a broad range of drainage applications.\u003c\/p\u003e\n\n\u003cp\u003eWater transfer is provided through a semi-open impeller designed specifically for drainage duties. The hydraulic passage allows particles up to 10 mm in size to pass through the pump, making it suitable for handling water containing small suspended solids. Working together with the stainless steel strainer, the pump can reduce water levels down to approximately 100 mm, helping remove accumulated water from pits, tanks and confined drainage areas.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with stainless steel components in contact with the pumped liquid, the unit provides excellent corrosion resistance and durability. Rated to IP68 standards, the pump supports liquid temperatures up to 50°C and submerged installation depths of up to 2 metres. A vertical float switch provides automatic operation in restricted spaces, while the integrated non-return valve helps reduce backflow within the discharge line.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVertical float switch designed for confined pit and narrow chamber installations.\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve helps reduce discharge backflow.\u003c\/li\u003e\n\u003cli\u003eMotor cooling jacket supports operation during periods of partial submersion.\u003c\/li\u003e\n\u003cli\u003e304 stainless steel wetted components provide corrosion resistance and durability.\u003c\/li\u003e\n\u003cli\u003eSemi-open impeller permits the passage of particles up to 10 mm in size.\u003c\/li\u003e\n\u003cli\u003e7 kg construction balances portability and installation flexibility.\u003c\/li\u003e\n\u003cli\u003eInternal thermal protection helps protect the motor during operation.\u003c\/li\u003e\n\u003cli\u003eSupplied with a 5-metre power cable.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50869028651255,"sku":"92533644","price":716.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-kp-250-av-1-stainless-steel-vertical-float-drainage-pump-for-chambers-with-semi-open-impeller.png?v=1781692301","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-kp-250-av-1-stainless-steel-vertical-float-drainage-pump-for-chambers-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
