FACTORY SERVICE AND REPAIR
With proper care, Tuthill Vacuum & Blower
Systems boosters will give years of reliable service.
The parts are machined to very close tolerances
and require special tools by mechanics who are
skilled at this work. Should major repairs become
necessary, contact the factory for the location of
the nearest service facility.
Current regulations require Material Safety
Data Sheet to be completed and forwarded
to Tuthill Corporation on any booster being
returned for any reason that has been handling
or involved with hazardous gases or materials.
This is for the protection of the employees of
Tuthill Corporation and the service facilities
who are required to perform service on this
equipment. Failure to do so will result in
service delays.
When returning a booster to the factory for
repair under warranty, please note the factory
will not accept any booster that arrives without
authorization. Contact Customer Service
Department for return authorization.
LONG-TERM STORAGE
Any time the booster will be stored for an extended
period of time, make sure that it is protected from
corrosion by following these steps:
1. Spray the interior (lobes, housing, and end
plates) with rust preventative. Repeat as
conditions dictate and at least on a yearly
basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a prominent tag stating that the
end covers are full of oil and must be drained
and refilled to proper levels before start-up.
4. Apply a rust-preventative grease to the drive
shaft.
5. Spray all exposed surfaces, including the inlet
and discharge flanges, with rust preventative.
6. Seal inlet, discharge, and vent openings. It
is not recommended that the booster be set
in place, piped to the system, and allowed to
remain idle for a prolonged amount of time. If
any component is left open to the atmosphere,
the rust preventative will escape and lose its
effectiveness.
7. During storage, ensure that the booster does
not experience excessive vibration.
8. Attach a desiccant bag to either of the covers
to prevent condensation from occurring inside
the booster. Make sure any desiccant bag (or
bags) is attached to the covers so that they will
be removed before start-up of the booster.
9. Store the booster in an air conditioned and
heated building if possible. If air conditioned
and heated storage is not possible, make
conditions as dry as possible.
10. If possible, rotate the drive shaft by hand at
least monthly in order to prevent seals from
setting in one position.
