BADU 21-40

This clever range of pumps are designed and manufactured to stringent quality specifications. Great care has been taken to keep the installation measurements as small as possible without sacrificing performance. The result is a compact, high performing range of pumps especially designed for jetted bath tubs, whirl pools, counter swim and cleaning units. The BADU 21 series are non self-priming, circulation pumps to be installed below the water level. This induces the self-drainage feature which ensures, for hygienic reasons, that all water is drained off when the bath is emptied.

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!
Discharge outlet swivels incrementally by 90°.
The unit may be installed in a vertical position with pump facing downwards.
Total electrical separation.
Threaded inlet and outlet connections suitable for special union
