Installation and Operations Manual

Discharge Piping
It is recommended but not required to exhaust the gases from the pump system outside (not into the room where the
system is installed).
For pump systems operating in parallel on a common discharge, we recommend the installation of a suitable check valve
close to the discharge. When discharging more than one pump in a common discharge line and/or over a long distance,
oversize pipe accordingly.
Following are the inlet and discharge connection sizes for the different pump models:
PUMP MODEL SIZE
10-15 1/2” NPT FEMALE
35 3/4” NPT FEMALE
50-70 1” NPT FEMALE
51-71 1” NPT FEMALE
100-150 1 ½” NPT FEMALE
200-270 2” NPT FEMALE
400-540 3” NPT FEMALE
Operation
At the heart of the Travaini Rotary Vane Vacuum Pump system is a reliable Rotary Vane Vacuum Pump. The pump
design and principle of operation provides ample clearance between the impeller and casing elements. Grease
lubricated bearings are mounted external from the pumping chamber, isolated by mechanical shaft seals. This means
that the pump requires no internal lubrication. The function of the seal fluid in the system is to create a liquid piston
action and to remove the heat of compression. The seal fluid in the system circulates in a closed loop. The heat
exchanger, either air or water-cooled removes the heat of compression. The discharge separator/reservoir holds the
seal fluid and incorporates a highly efficient separator arrangement to separate the seal fluid from the air or gases
discharged by the pump system.
Pump Lubricant
All pumps are shipped dry without oil. A charge of our factory recommended lubricant is shipped in a separate container
with each pump. Before filling the pump with oil, check that the pump is installed level. Fill the pump with the
recommended lubricant (see table below) through the oil fill plug until it reaches the ½ way mark of the upper sight glass.
WARNING: Do not overfill the pump.
Do not add or fill when the pump is running.
Do not fill oil through the inlet or exhaust port.
We recommend the use of our specially formulated Travaini oils for obtaining ultimate performance from your vacuum
pump. The specially formulated Travaini oil is a high quality vacuum pump oil that provides better lubrication at high
operating temperatures and prolongs the life of the pump and exhaust filters. When our specially formulated Travaini oils
are used in new pumps shipped from the factory pump will be covered by an extended warranty period. For extended
warranty information see the front of this manual.
