The BADU 21 AK-SSV range pumps are designed for the specific demands of bath tubs, whirlpools, counter swim units and cleaning devices. All models in this range are non-self-priming circulation pumps, which cannot handle air. These pumps are to be installed below the water level in order for the pool water to drain independantly.
The special version AK pumps for salt water, seawater and brine correspond to the standard versions in the BADU programme, however they are designed for use in diverse salt water and problem medias. Media that could potentially leak or minerals and salts which could crystallise do not come into contact with the motor or bearings. Therefore this ensures considerably longer operating times for these fields of application compared to the standard version.
Field of application:
thermal waters, brine water, seawater aquarium with artificially treated salt water, pickle plants and many problem mediums after verification of components and concentration. In principle, the medium is to be stated precisely to allow for verification of the pumps' resistance capabilities.
Use of the pumps for pools and their security zone is only permitted, if they are constructed according to DIN/VDE 0100 part 702. Please talk to your qualified electrician!
The electrical connection should generally be installed and carried out by a qualified electrician.
