1 Description
TRIVAC B pumps are oil-sealed rotary vane pumps. The
TRIVAC S 40 B and S 65 B are single-stage pumps, and
the TRIVAC D 40 B and D 65 B are dual-stage pumps.
The number in the type designation (40 or 65) indicates
the pumping speed in m

x h

.
TRIVAC B pumps can pump gases and vapours and
evacuate vessels or vacuum systems in the fine vacuum
range.
Those of standard design are not suitable
for pumping greater than atmospheric
concentrations of oxygen, hazardous
gases, or extremely aggressive or corrosive
media.
The drive motor of the TRIVAC B is directly flanged to the
pump at the coupling housing. The pump and motor
shafts are directly connected by a flexible coupling. The
bearing points of the pump module are force lubricated
sliding bearings. All controls as well as the oil-level glass
and the nameplate are arranged on the front. All
connections are to be found at the sides of the pump.
The oil-level glass is provided with prisms for better
observation of the oil level.
The pump module consists of assembly parts which are
pin-fitted so as to allow easy disassembly and
reassembly. The pump module can be easily removed
without special tools.
