All pumps from the D4B to the D25B model are equipped either with single= phase or three-phase motors. D40-65B models are equipped with three-phase motors. Moreover, all pumps of the B series are available also without the motor. In the Trivac B, the pump unit and the motor are linked by an elastic coupling.
The TRIVAC B range is a modular system which divides into three groups : TRIVAC 4/ 8 Series, TRIVAC 16/ 25 Series, TRIVAC 40/ 65 Series
