SPECK Pumpen supplies practical opening devices for the BADU swimming pool circulation pumps. Toggle screws or cap nuts, partly exposed to corrosion, are therefore a thing of the past. The strainer tank lid can be opened easily with just one handle. There are three different universal opening aids, which cover the whole range of product types in the BADU series. The three way opening device is suitable for both the filter lid and for the 90 d or 110 d pump screws and is attached to the grooves of the lid from above. Letters are marked on to help find the correct position and radius. The lid is released by turning it in an anti-clockwise direction. It can be used for the BADU Resort, BADU Eco Flow, BADU 90/40 Eco MV-E and BADU 90/25 – 90/48 or 90 d or 110 d pump screws.
