Xylem P2001406B Series e-1510 Centrifugal Pumps - Manual (Page 16)

Guideline Explanation/comment
When possible, locate the pump below the fluid
level.
This facilitates priming, ensures a steady flow of liquid, and
provides a positive suction head on the pump.
Foundation requirements
Requirements
• The foundation must be able to absorb any type of vibration and form a permanent,
rigid support for the unit.
• The foundation must weigh at least 2-1/2 times the weight of the pump unit.
• Provide a flat, substantial concrete foundation in order to prevent strain and distortion
when you tighten the foundation bolts.
• Sleeve-type and J-type foundation bolts are most commonly used. Both designs allow
movement for the final bolt adjustment.
• Tie the concrete pad in with the finished floor.
• Use foundation bolts and larger pipe sleeves to give room for final bolt location.

Piping checklist
WARNING:
• The heating of water and other fluids causes volumetric expansion. The associated
forces can cause the failure of system components and the release of high-
temperature fluids. In order to prevent this, install properly sized and located
compression tanks and pressure-relief valves. Failure to follow these instructions can
result in serious personal injury or death, or property damage.
• Avoid serious personal injury and property damage. Make sure that the flange bolts
are adequately torqued.
• Never force piping to make a connection with a pump.
Check Explanation/comment Checked
Check that a section of straight pipe, with a length that
is five times its diameter, is installed between the
suction side of the pump and the first elbow, or that a
B&G Suction Diffuser is installed.
This reduces suction turbulence by
straightening the flow of liquid before it enters
the pump.
