VACUUM CONNECTIONS
Use a pipe size that is at least equal to the size of
the pump inlet connections. Smaller lines result in
a reduced pump capacity and performance.
For pumps operating in parallel on a common main
line, install a manual or automatic operated shut-off
valve or a positive action check valve in the suction
line adjacent to the pump suction flange. Do not
use the built-in anti-suckback valve as a shut-off
valve for the vacuum system.
Remove the plastic protective cap from the inlet
port before connecting the pump to the system.
Should process gas contain dust or other foreign
particles, connect a suitable inline (inlet) filter to
the inlet port. Consult Tuthill Vacuum & Blower
Systems for recommendations.
Design the vacuum piping so that no liquids such
as condensate or liquid carried over from the
process can reach the pump. If this possibility
exists, install a knock-out liquid separator.
Consult Tuthill Vacuum & Blower Systems for
recommendations.
If an exhaust manifold is connected, install a drip
leg and drain near the pump exhaust to prevent
exhaust condensation from entering the exhaust
box. The thread sizes in Table 3-1 are standard on
KVA pumps:

FILLING THE PUMP WITH OIL
The pump is shipped without oil. After level
installation and correct rotation has been
established, fill the pump with the recommended
motor oil through the oil fill port. The oil level
should be at the 3/4 mark on the oil sight glass.
Use a non-detergent oil. Oil detergent additives
can clog exhaust filters and shorten their
service life. Tuthill Vacuum & Blower Systems
recommends KV-100 oil for normal duty operation
or S500 oil for severe duty operation.
Table 3-2 gives the approximate quantities of oil
required for each model.
Table 3-2
PUMP MODEL OIL CAPACITY
KVA12 / KVA21 0.5 qt (0.5 L)
KVA25 / KVA40 1.5 qt (1.4 L)
KVA63 / KVA100 2.6 / 2.9 qt (2.5 / 2.7 L)
KVA160 / KVA250 7.4 qt (7.0 L)
KVA400 20.0 qt (19.0 L)
KVA630 20.0 qt (19.0 L)
WARNING !
Do not add or fill oil with pump running or
through the inlet or exhaust ports! Do not
overfill.
