Circulation pumps, non self-priming



BADU 73

BADU 73
The non-self priming circulation pump BADU 73 has been designed especially for use with filter units in private swimming pools and whirl pools, with higher resistances, for example if the distance between pool and filter unit is very long.

Due to the pump’s higher head with 2 and 4 bar respectively, it can be utilized for additional functions, this includes the use as "pressure cleaner", circulation of pool water and connection to different filter units as well as to bottom cleaners.

According to the applications required the BADU 73 is available as single-stage (up to a maximum of 2 bar) and two-stage version (up to a maximum of 4 bar).

The extensively tested and proven BADU range continues to set new standards in the industry. The high quality of materials used such as the glass fibre reinforced plastic, the stainless steel wear ring and service-free sealing ensure its top performance.
Constructional features
Corrosion resistant – due to high quality glass fibre reinforced plastic.
Non-self priming – pump to be installed below water level.
Reliable sealing – service-free, closed bellows-type mechanical seal.
Secure – total electrical separation between pool water and electric parts.
Design
Monoblock-type pump with a bellows-type mechanical seal mounted on a plastic shaft protector sleeve.
Motor/pump shaft has no contact with the pool water!
Total electrical separation.
