Two Really Old Questions! What can we change? How much will it cost?
An equally old answer What do you need? That depends!
Key considerations What do you need to do? What will it take to do it? Effectively planning for change
Common topics/questions • How can pump upgrades impact operational capability?
BLUF: (Bottom Line Up Front) Pump efficiency has not improved much Motors are marginally better Savings are found in controls and proper application
Understand your system curve Use less than full-sized impellers Control with VFDs
Common topics/questions • How can pump upgrades impact operational capability? • What is the cost range for pump upgrades? • Ongoing O&M needs for pump upgrades or operational improvements • The range of energy/cost savings from pump upgrades & operational improvements
