Installation
Manual 1843 Rev B p/n 001843 0000
If the studs are not already installed into the
vibramounts, thread the short end into the top of
the mount (smaller diameter) up to the spacer
portion of the stud.
The vibramount attachment holes are the four open
threaded holes in the flanged edges of the cylinder,
in line with the bottom plate/cylinder bolts, just in
from each corner of the pump.
WARNING
!
Do not use the four unthreaded holes, these
are used for shipment only.
With the pump lifted off the ground, thread the
vibramounts with studs into the vibramount
attachment holes until contact is made between
the top of the vibramount and the cylinder bottom
plate, and the foot location is parallel to the pump
shaft.
See Pump Assembly – KT-150, KT-
300, KT-500, KT-850 on page 36
for KT850
vibramount locations, as the vibramounts are not
interchangeable on this model.
Carefully set the pump down squarely on the mounts
when installing the pump in operating position.
If the KT pump was supplied as a part of a system,
with the vibramounts pre-installed, ensure that
any shipping retention bolts or spacer tubes are
removed before startup. To avoid damage to
the pump, it should be solely supported by the
vibramounts when in operation.
PIPING CONNECTIONS
Manifolding should be no smaller than the pump
connections in oder to minimize restrictions to gas
flow. Accurately align the mating flanges to the inlet
and discharge manifolding to prevent distortion of
the pump housing.
WARNING
!
Pipe loading on the pump should be
negligible as pipe loading can cause
distortion of the pump. Use proper supports
and pipe hangers to assure that there is no
loading.
Main Piping
Suction Manifolding
Inlet manifolding should be sized and designed
with four objectives in mind:
•
To avoid gas flow restrictions.
•
To prevent pump fluids from entering the
process chamber.
• To protect the pump from ingesting particulate
matter.
• To allow proper venting of the pump and suction
manifold.
Under normal conditions, the diameter of the
manifolding should not be less than the diameter of
the pump connection, and the pipe length should
be kept to a minimum.
Oil may splash from inside the pump through the
suction port, so the suction line must be designed
to prevent oil from collecting there and draining
back to the system or process.
See Figure 5-1
for recommended arrangement as a guide for
fabricating inlet manifolding.
Proper standard inlet manifolding is available
from Tuthill as a factory-installed or aftermarket
accessory.
