Pump location guidelines
WARNING:
Assembled units and their components are heavy. Failure to properly lift and support this equipment can
result in serious physical injury and/or equipment damage. Lift equipment only at the specifically identified
lifting points. Lifting devices such as eyebolts, slings, and spreaders must be rated, selected, and used for
the entire load being lifted.
Guideline Explanation/comment
Make sure that the space around the pump is
sufficient.
This facilitates ventilation, inspection, maintenance, and
service.
If you require lifting equipment such as a hoist
or tackle, make sure that there is enough space
above the pump.
This makes it easier to properly use the lifting
equipment and safely remove and relocate the
components to a safe location.
Protect the unit from weather and water damage
due to rain, flooding, and freezing temperatures.
This is applicable if nothing else is specified.
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
engineer or architect in charge before you operate the
pump.
Take into consideration the occurrence of
unwanted noise and vibration.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil
underneath.
Concrete foundation requirements
Requirements
Make sure that you meet these requirements when you prepare the pump foundation:
• The foundation must be able to absorb any vibration.
• The foundation must be able to form a permanent and rigid support for the pumping unit.
• The foundation must be of adequate strength in order to support the complete weight of the pump
and driver, plus the weight of the liquid that passes through it.
• There should be at least 0.5 in.(12.7 mm) clearance between the sides of the pump and any portion of
the pit.
Typical installation
A typical installation has these characteristics:
• Bolts with a pipe sleeve that is two and a half times the size of the bolt diameter embedded in the
concrete
• Properly sized
• Located in accordance with the dimensions given in the example drawing
• Enough space inside the pipe sleeves to allow the final position of the foundation bolts to align with
the holes in the sub-base flange
