V-Pump housing

Non-return valve and ball shut-off valve installed, with insulating cover, with union set, standard with screw / brazed fitting 1/2" external / ø 15 internal.


Electronic regulating thermostat

Thermostat switch-off temperature selectable in increments of 5 °C, from 35°C to 75°C, switch-on point 7 K below the switch-off temperature, with mode indicator, Dauerlauf. und Dauerstopp-Funktion

One Touch Technology

One Touch technology on all pumps with control module. The benefit: All functions can be controlled at the touch of a button.

Cap or Control Modul

Pumps BWO 155 without a control module can be retrofitted with a control module by just replacing the cap.



The spherical motor does not feature a revolving bearing shaft, the stator transfers the magnetic field to the permanent magnetic rotor located in the water-carrying part of the pump. The water-carrying part of the pump is hermetically separate from the stator by a spherical cap.
The rotor bearing is self-adjusting and lubricated by the medium. The rotor can be easily cleaned or replaced.


Highly efficient electronically commutated direct current motor (ECM technology) with silky smooth operation.
Lower power consumption (2-7 W) but still strong (0.6 - 1.3 m)
