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.
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 for air cooled pumps (See Figure 10):
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 water cooled pumps (See Figure
11):
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.
Combination Deaerator/Thermal Buff er/
Expansion Tank
Fulton Thermal’s effi cient design combines the operation
of the expansion, deaerator, and thermal buff er tanks.
Installation is considerably simplifi ed by virtue of this
arrangement. See Figures 12 and 13.
The expansion section is vital to the thermal fl uid system.
From ambient to operating temperature, the thermal fl uid in
the system will typically expand in the range of 25% to 50%,
and a vessel capable of handling this expansion is mandatory.
The customer should confi rm the expansion rate of the
chosen fl uid and system volume.
At start up, the primary purpose of the deaerator section
is to remove all volatiles from the system to avoid pump
cavitation. The deaerator section also allows air to be vented
from the system on a continuous basis during operation
to avoid oxidation of the thermal fl uid, and removes other
volatile particles generated by the fl uid itself during system
