SAMPLE SLIDES OF THE 2-DAY SEMINAR FOR ENGINEERS
As you will notice there are few words on these slides, your trainer will provide you with his experience which will make these images
come alive providing you with the opportunity to reflect and ask questions, the more the
better.
All of the presentation slides are available in a binder supplied with the seminar.

HYDROSTATIC PRESSURE VS. FLUID COLUMN HEIGHT
The weight of a fluid column is:AzVAzVgVF since
Pressure (p) is equal to the weight of the fluid (F) divided by the surface area (A) at the bottom of the fluid column:

1. Replace a standard motor with a high efficiency motor
Replace a standard efficiency motor with one that meets or surpasses the NEMA Premium standard
Typically 1.5 to 5% and as much as 8%
When the motors are defective or at the end of their useful life or when a motor must be replaced to accommodate a VFD.

2. Install a variable frequency drive (VFD)
A VFD can adjust the speed of a motor in response to a variable demand avoiding the throttling of control valves or the opening of recirculation control valves and the energy losses incurred.
Typically 12 to 15% and as
much as 27%
Ideal solution when the flow
varies between 40 and 60%
