TRIVAC B, Two-Stage Rotary Vane Vacuum Pumps TRIVAC D 4 B to D 65 B
The TRIVAC B is the logical step ahead within the well-proven TRIVAC concept. Here the performance and the characteristics of the pumps have been adapted without compromise to market requirements.
The TRIVAC B pumps with their comprehensive range of accessories have proven themselves time and again as rugged pumps in many and varied applications. The inner body is assembled from individual parts without sealing components. The parts are pinned in order to ensure easy disassembly and reassembly of the parts.
All pumps from the D 4 B to the D 25 B model are equipped either with single-phase AC or three-phase AC motors. D 40 - 65 B 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
