1 Description
The TRIVAC D 2,5 E-LD is a dual stage oil sealed rotary vane vacuum
pump.
The number in the designation of the pump indicates the pumping speed
of the pump in m
3
· h-1.
These pumps are capable of pumping gases and vapours out of vessels
and vacuum systems down into the fine vacuum pressure range. The
standard pumps are not designed to handle oxygen at concentrations
exceeding the concentration of oxygen in the atmosphere. Moreover, these
pumps are not suited for pumping of hazardous gases or extremely
aggressive or corrosive media.
The drive motor of the TRIVAC D 2,5 E-LD is screwed directly to the
bearing piece. The shaft of the pump and the shaft of the motor are linked
by a coupling piece. The bearings in the inner pump body are forcelubrica-
ted sliding bearings.
The oil level glass for viewing the minimum/maximum oil level and the oil
drain plug as well as the name plate are located on the front of the pump.
The connection components, the gas ballast knob and the oil fill plug are
located on the top of the pump.
