WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
No shutoff of any kind may be
placed between the safety relief
valve and the equipment, or in the
discharge pipe between such valve
and the atmosphere. Doing so may
cause accidental explosion from
overpressure.
Discharge from safety relief valve
must be confi gured so that there
is no danger of scalding personnel
or causing equipment damage.
Provisions must be made to properly
drain safety relief valve discharge
piping.
pump manufacturer’s installation and operation instructions can be obtained
from the manufacturer.
Adhere to the following for pump installation:
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.
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 cooled pump and should be fi lled
with lubricating oil recommended by the manufacturer. The suggested
lubricant is usually a SAE-30 non-detergent oil.
