BADU 21-41
Circulation pumps, non self-priming



BADU 21-41

BADU 21-41
The pumps of the BADU 21 series are especially designed for jetted bath tubs, whirl pools, counter swim and cleaning units. All versions of this series are non self-priming circulation pumps, what means that no air can be suctioned. The pumps have to be installed below the water level. This induces an unassisted feed of bathwater.
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
