On the KT-1350VFP install one black spring at the belt drive end on the suction port side, one white spring at the oil mist eliminator
end on the suction port side, and both gray springs on the gas ballast side. The vibrasprings may not work correctly if they are not
installed in the correct locations.
Care must be taken to set the pump down squarely on the mounts when installing the pump in operating position.
SUCTION MANIFOLDING
Inlet manifolding should be sized and designed with these objectives in mind:
•
To avoid gas flow restrictions
• To prevent pump fluids from entering the process chamber
• To protect the pump from the ingestion of particulate matter.
• To allow proper venting of the pump and suction manifold.
Under the 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 2 for
recommended arrangements as a guide for fabricating inlet manifolding.
A flexible connection should be installed in the suction manifold to provide freedom for
vibramounts. The vacuum piping must be well aligned with the pump connections so as not to
place a strain on the piping.
Provisions for gauge installation and any other drilling in the piping must be made prior to piping
installation, otherwise, drilling particles entering the piping could be entrained into the pump.
A vacuum isolation valve should be installed adjacent to the suction port to be used for leak
checking, shutting down the system, or blanking off the pump.
PROPER VENTING
The vacuum pump must be properly vented to insure all oil is removed from the pumping chamber before the pump is turned off.
Also, the suction line must be properly vented to insure oil does not migrate into the process chamber. Recommended vent valve
sizes are: KT-840VFP - 1 ½ inch; KT-1350VFP - 2 inch
Vent valve must be open at least 10 seconds before the pump is turned off to remove all oil from the pumping chamber.
Before connecting the suction manifolding, distribute 4 quarts of oil over the three slide pins. This will require reaching through the
suction port with a container and pouring oil directly onto the slide pins. Then rotate the pump by hand a minimum of two revolutions
to distribute the oil throughout the pump interior.
During the initial operation and as long thereafter as necessary, a fine mesh screen should be installed across the inlet connection
to prevent abrasive or solid particles left in the line from being sucked into the pump. This screen can be removed when particles
no longer accumulate. If particles continue to accumulate, a filter should be installed in the line.
DISCHARGE MANIFOLD
KT-LP Series pumps have an integral oil mist eliminator which should prevent oil mist being present in the discharge manifolding. It
may be necessary to pipe the pump exhaust fumes away from the pump area, such as out of doors. If this is done, the piping must
be arranged to prevent line condensation from returning to the pump. A flexible connector should be fitted in the discharge line to
provide freedom for the vibramounts.
Under the 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.
COOLING WATER
The cylinder cooling water jacket is shipped dry, with the drain plugs removed. They are tied to the pump in a small cloth bag.
Replace the plugs in the positions shown in Figure 1 and fill the water jacket before starting the pump.
