INSTALLATION

 Grafoil packings require a run-in procedure. Typically,
pumps with these seals are shipped with four or fi ve
rings installed and several rings loose. These extra rings
must be on hand for the initial run-in procedure. See
manufacturer’s instruction manual for this procedure.
 Requirements for Air Cooled Pumps
Adhere to the following (See Figure 11):
1. Allow for free air fl ow around the entire pump casing at
all times.
2. Maximum room temperature should be 100°F (38°C).
3. In no case should any part of the drive side of the pump
be insulated.
4. Maximum operating temperature for air cooled pumps
varies by manufacturer. Consult instruction manual to
verify.
 Requirements for Water Cooled Pumps
Adhere to the following for (See Figure 12):
1. Requirements for water cooled pumps will vary with
manufacturer. Consult manufacturer’s instructions for
fl ow rate and temperature requirements.
2. Check local codes regarding disposal of hot water.

 The coupling alignment of the pump and driver must
be carefully checked for angular and axial alignment.
Check pump manufacturers instructions for these
specifi cations. The use of a dial indicator to check the
axial and angular alignment is recommended.
 An air cooled pump does not have an oiler. This type
of pump has a sleeve bearing which is, like the seals,
lubricated by thermal fl uid. An air cooled pump has a
grease nipple located at the drive end of the pump near
the coupling connection. This comes pre-greased, and
should be greased at intervals as recommended by the
manufacturer.
 An oiler is shipped with each water colled pump and
should be fi lled with lubricating oil recommended by
the manufacturer. The suggested lubricant is usually a
SAE-30 non-detergent oil.
 Thermal fl uid is not suffi cient lubrication for bearings.
 All seals on air cooled pumps are lubricated by thermal
fl uid, therefore the pump must never be run dry, i.e.,
without thermal fl uid in it.
 Filling a pump equipped with either a Grafoil packed
or mechanical seal with thermal fl uid will ensure
lubrication. However, in order to be certain that all seals
on an air cooled pump are coated with thermal fl uid,
the pump must be bled.
