Xylem P81673H Series 1510 - Manual (Page 16)

Guideline Explanation/comment
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.
If the pump location is overhead, undertake special
precautions to reduce possible noise transmission.
Consider a consultation with a noise specialist.
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.
