5.2 LUBRICATION
The KINNEY KT Pump is lubricated by a pressurized oil system. A positive displacement pump generates
oil pressure. KT Vacuum Pumps use Tuthill KV100 oil. KV100 is used for factory testing and the initial
charge is shipped along with the pump. It is necessary to utilize this oil to maximize pump life, achieve
design intents and maintain full warranty. Contact the Factory for review of a desired substitute or inert oils.
The lubricating Gear Pump is mounted on the closed head and is driven directly by the vacuum pump
shaft. Failure of the gear pump may be detected by reduced oil pressure, deteriorating performance, noise,
unusually high temperature and lower temperature of oil line tubing. The tubing should be nearly the same
as the oil temperature or 145 to 165°F (63 to 75°C). If utilizing the high oil temperature switch option it
should be set at 190° F (88° C).
KT pumps are equiped with an oil pressure gauge that should indicate at least 20 PSIG. (1.4 bar) (KT 500
& KT850) and 25 PSIG (1.7 bar) (KT 150 & KT 300).
WARNING
Never attempt to change or add lubrication while the pump is running.
Failure to heed this warning could result in damage to the equipment or
personal injury.
WARNING
Properly dispose of the spent lubricants. Refer to the manufacturer of the
lubricant and any regulations to assure proper and safe disposal.
NOTE
These pumps do not have a bypass valve on the oil pump and pressure
may exceed 150 PSIG (10 bar) on cold start up.
NOTE
If the oil level is too low, bearings and seals will be damaged as a result of
improper lubrication.
5.2.1 HAZARDS ASSOCIATED WITH BREAKDOWN OR IGNITION OF LUBRICATION
DANGER
There is a risk associated with the lubrication media breaking down and
resulting in a hazardous fluid or vapor. There may also be a hazard
associated with the ignition of the lubrication media. Refer to the lubrication
manufacture’s applicable instruction for safety precautions.
