 Thermal Fluid Circulating Pump
Installing the pump in accordance with the manufacturer’s
specifi cations and these instructions will prolong the life
of the pump and contribute signifi cantly to the successful
operation of your Fulton heater system. The pump
manufacturer’s installation and operation instructions can be
obtained from the manufacturer.
Adhere to the following for pump installation (see Figure 9):
1. Locate pump adjacent to the heater. Its base must be
fi rm, level (preferably concrete), and free from vibration.
2. Route pump per the manufacturer’s requirements. It
should be equipped with fl exible connections at the
suction and discharge sides. The primary function of
these connections are to prevent stresses due to pipe
expansion from being placed on the pump and to
isolate pump vibrations from the pipe work and the
heater. They also allow for expansion and defl ection of
the pipe work. These connections should be rated for
high temperature since they are considered part of the
piping system.

3. Connect suction pipe work directly to the deaerator
section via a vertical run with as few elbows as possible.
It should contain the strainer and an isolating valve.
The discharge pipe work must be connected directly to
the heater inlet, and should contain an isolating valve.
See that pipe work connections match up accurately
with pump fl anges. Refer to the pump manufacturer’s
recommendations for the specifi c pump inlet piping
requirements. Typically these requirements are that:
 It be a straight run of pipe.
 The straight run from the pump inlet to the fi rst fi tting,
valve, or fl ex connector be a minimum of 6-10 pipe
diameters in length.
 The pipe used should be the same size as the inlet of
the pump.
 The piping in the immediate vicinity of the pump
must not be supported by the pump. The pump is not
designed to bear the weight of the piping, and weight
on any part of the pump will throw it out of alignment.
 Proper alignment directly aff ects bearing, coupling,
and seal life expectancy. The pump is properly aligned
before it leaves the factory. Because the system expands
in operation, pump must be realigned when the system
is at operating temperature.
