US VACUUM Torrvac Series, Installation & Operation Manual

OIL FILLING
The pump is shipped without oil. After level installation and correct rotation has been established, fill the pump with
recommended oil through the oil fill port. Oil level should be at the 3/4 position on the UPPER sight glass.
Non-detergent oil should be used. US Vacuum recommends US-550SS oil which provides long running time be-
tween oil changes and high temperature operations. When US Vacuum pump oil is used, the warranty period is
extended to 18 months.
Oil capacity: TV-25B/TV-40B: 1.5 quarts ; TV-63B: 2.5 quarts; TV-100B: 2.7 quarts, TV-160B/250B: 7 quarts
TV-630B: 16 quarts
CHANGE OIL EVERY 500-750 OPERATING HOURS
Check the oil for contamination on a weekly basis by shutting the pump off and draining some of the oil
into a small glass or container through the oil drain port.
Oil life is dependent upon the condition to which it is exposed. The oil must be changes after the first
100 hours of initial operation. After the initial oil change, and when using US550-SS (Semi-synthetic oil),
it is recommended that the oil changes are made every three (3) or four (4) months or 500-750 hours of
operation, or as necessary if high heat is contaminating the oil.
To change the pump oil, the pump must be switched off and ventilated to reach atmospheric pressure.
Remove the oil drain plug and drain the oil. Dispose of the oil in compliance with local or national
regulations. When oil stops draining, replace the oil drain plug.
Start the pump again for a few seconds. Stop the pump once again, and then reopen the oil drain plug
and discharge any remaining oil.
Refasten the oil drain plug. Remove the oil filter and replace it with a new one using a US Vacuum
genuine oil filter. Make sure to tighten the filter securely against the aluminum sealing surface so that
leaks will not occur.
EXCESSIVE HEAT:
When the pump is subjected to operating conditions that will cause the oil to be heated above 210 Deg
F, the oil will carbonize and become contaminated after a relatively low number of operating hours if
standard hydrocarbon oil is used. The higher the temperature, the quicker the oil becomes contaminated
and thermally breaks down. In these type of high heat applications, US550SS oil is recommended.
CONTAMINATED AIR STREAM
When the air stream contains solids and/or liquids that may contaminate the oil, the oil must be changed
more often. If the air stream contains a small percentage of particulate matter, the solution is to install a
pre-filter or knock-out pot to keep the contaminates out of the pump.
