extra rings must be on hand for the initial run-in

for this procedure.
 Requirements for Air Cooled Pumps
Adhere to the following for air cooled pumps (See Figure
6):
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 7):
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’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.
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
operation. This section of the tank must be insulated.
A system of interconnecting pipe work in the thermal buff er
tank section prevents the movement of any oil that has not
cooled suffi
ciently into the expansion section. This avoids
contact of very high thermal fl uid temperature with oxygen
contained in the atmosphere, which causes fl uid breakdown.
DO NOT insulate this section.
