Today we will take a look at some of the finest oil sealed 2 stage vacuum pumps on the market. The Leybold Trivac B and BCS series have set the standard for excellence for years.
Reliable vacuum pumps for long lasting operation and rough applications.
Oil sealed rotary vane vacuum pumps are being used in all areas of vacuum engineering. They are equally suited for both industrial production and research applications. They may be used to generate a rough and medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps.
The TRIVAC B is part of the well-prov-
en TRIVAC concept.
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
