WATCH THE VIDEO NOW to see how the UNILIFT APG handles its business with flying colours in this case story from Melbourne, Victoria.


The Grundfos UNILIFT APG is equipped with a class leading grinder mechanism, which is so efficient it greatly reduces the possibility of flooding and blockages where foreign objects get jammed, backing up cisterns or flooding pits.

Based on Grundfos’ industrial SEG wastewater pump range, the UNILIFT APG's industrial grinder blade can cut the toughest and most challenging wastewater and storm water run-off debris (including everything from diapers and sanitary wipes to face masks and garden waste) into small pieces and is a versatile and reliable pumping solution for moving domestic wastewater or stormwater over long distances.


UNILIFT APG comes with multiple connection options, making it easy to install into existing pits or match with existing pipework. It features a flanged connection (which suits DN32 or DN40 connections) and a threaded 40mm/1 1/2" threaded connection for quick attachment .

What's more, the UNILIFT APG's lighter weight allows for easier maintenance without the need for rails and chains.



Installed in a tank solution in basements and other building spaces below sewer level.
