TRIVAC B, Two-Stage Rotary Vane
The TRIVAC B is part of the well-prov- en TRIVAC concept

Description

HIGHLIGHTS

The TRIVAC B pumps with their com- prehensive range of accessories have proven themselves time and again as rugged pumps in many and varied applications .

The inner body is assembled from indi- vidual parts without sealing compo-nents . The parts are pinned in order to ensure easy disassembly and reas- sembly of the parts .

All pumps from the D 4 B to the D 25 B model are equipped either with single-phase or three-phase motors . D 40 – 65 B models are equipped with three-phase motors . In the TRIVAC B, the pump unit and the motor are linked by an elastic coupling .

The TRIVAC B range is a modular sys- tem which divides into three groups:
TRIVAC 4/8 Series
TRIVAC 16/25 Series
TRIVAC 40/65 Series
