BADU 21-50

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.

Field of application

Large whirl pools, hotel pools, pool and industrial filtrationunits, counter swim units, massage stations, air conditioningunits, cleaning units and many other applications with a flowrate up to 54 m³/h.

Design

Monoblock-type pump with a bellows-type mechanical seal mounted on a plastic shaft protector sleeve.
Discharge outlet swivels progressively.
Total electrical separation.
Threaded inlet and outlet connections suitable for special union
