Guideline
Explanation/comment
Do not install and operate the equipment in closed
systems unless the system is constructed with
properly-sized safety devices and control devices.
Acceptable devices:
•
Pressure relief valves
•
Compression tanks
•
Pressure controls
•
Temperature controls
•
Flow controls
If the system does not include these devices, consult the engi-
neer or architect in charge before you operate the pump.
Take into consideration the occurrence of unwant-
ed noise and vibration.
The best pump location for noise and vibration absorption is on
a concrete floor with subsoil underneath.
If the pump location is overhead, undertake special
precautions to reduce possible noise transmission.
Consider a consultation with a noise specialist.
4.1.2 Foundation requirements
Requirements
•
Provide a flat, substantial concrete foundation in order to prevent strain and distortion when you
tighten the foundation bolts.

4.2.1 General piping checklist
Precautions
WARNING:
•
Risk of premature failure. Casing deformation can result in misalignment and contact with
rotating parts, causing excess heat generation and sparks. Flange loads from the piping
system, including those from the thermal expansion of the piping, must not exceed the
limits of the pump.
•
Risk of serious personal injury or property damage. Fasteners such as bolts and nuts are
critical to the safe and reliable operation of the product. Ensure appropriate use of fasten-
ers during installation or reassembly of the unit.
•
Use fasteners of the proper size and material only.
•
Replace all corroded fasteners.
•
Ensure that all fasteners are properly tightened and that there are no missing fas-
teners.
NOTICE:
Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the
suction side. This action can result in decreased performance, unexpected heat generation,
and equipment damage.
