These are separate limits. Actual flow depends on lift and pipe resistance; use the matching 50Hz curve to assess expected flow.\u003c\/p\u003e\u003cp\u003eThe vertical outlet is 50mm (2\") Rp \/ BSP female. Maximum spherical particle diameter is 50mm. Suitable for water containing small amounts of suspended solids, but not stones, long fibres, aggressive or flammable liquids.\u003c\/p\u003e\u003cp\u003eSuitable uses include collecting pits, dirty stormwater, groundwater lowering, suitable laundry and bathroom wastewater, and suitable septic-system effluent. This model excludes sewage and toilet discharge.\u003c\/p\u003e\u003cp\u003eThe supplied tethered float starts and stops the pump automatically. Adjust its free cable length to set the difference between start and stop levels, and maintain free float movement.\u003c\/p\u003e\u003cp\u003eThe motor cooling jacket supports continuous running without scheduled cooling rests while partly submerged, provided the entire inlet strainer remains submerged in the liquid being pumped. Do not run dry.\u003c\/p\u003e\u003cp\u003eInstall on a firm base clear of sludge and mud. Allow a minimum pit diameter of 550mm and depth of 600mm at the minimum free float-cable setting. Maximum installation depth is 7m with the 10m cable; leave at least 3m of cable above liquid level. Lift by the handle. A union, non-return valve and isolating valve are recommended for permanent pipework.\u003c\/p\u003e\u003cp\u003eSupply is 220-240V single phase, 50Hz. Input P1 is 1.6kW and motor output P2 is 1.1kW. A 10m cable and Australian plug are supplied. Internal thermal overload protection resets after cooling; no separate motor-protection control box is needed.\u003c\/p\u003e\u003cp\u003eThe housing and vortex impeller are AISI 304 stainless steel. Liquid temperature is 0-55°C and pH is 4-10. The removable inlet strainer gives access for cleaning.\u003c\/p\u003e\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/6723\/4071\/files\/Grundfos_UNILIFT_AP35_AP50_Official_Technical_Data.pdf?v=1792246910\"\u003eUNILIFT AP35 \/ AP50 Official Technical Data\u003c\/a\u003e\u003cbr\u003e\n\u003ca target=\"_blank\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/6723\/4071\/files\/Grundfos_UNILIFT_AP35B_AP50B_Official_Data_Booklet_Extract.pdf?v=1792246910\"\u003eUNILIFT AP35B \/ AP50B Official Technical Data\u003c\/a\u003e\u003cbr\u003e\n\u003ca target=\"_blank\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/6723\/4071\/files\/Grundfos_UNILIFT_AP_Installation_3279044.pdf?v=1792243026\"\u003eUNILIFT AP Installation \u0026amp; Operating Instructions\u003c\/a\u003e\u003cbr\u003e\n\u003ca target=\"_blank\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0759\/6723\/4071\/files\/Grundfos_UNILIFT_AP35B_AP50B_Installation_Current_English.pdf?v=1792246910\"\u003eUNILIFT AP35B \/ AP50B Installation \u0026amp; Operating Instructions\u003c\/a\u003e\u003c\/p\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":45773446905879,"sku":"PUGR96023935","price":2042.28,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/6723\/4071\/files\/grundfos-unilift-ap50-50-08-a1v-96023934.png?v=1792246856","url":"https:\/\/perthirrigation.com.au\/products\/grundfos-unilift-ap50-50-11-a1","provider":"Perth Irrigation","version":"1.0","type":"link"}
