Session 1: Centrifugal Pumps
9:00 a.m. – 11:30 a.m.
Instruction will focus on the following areas:
- End-Suction (Lev Nelik, Pumping Machinery, LLC): Instruction will include both theory and hands-on, re-assembly of single-stage, end-suction ANSI centrifugal pumps. Participants will learn to read and interpret pump performance curves, head-capacity, efficiency, power, impeller trim effect on performance, affinity laws, NPSH, cavitation/recirculation issues, design features evaluation, applications and troubleshooting methods. This session will also include performance testing of two sample pumps operating in parallel mode and instruction about plotting performance curves.
- Submersible Pumps (John Ondrejack, Flowserve, Municipal Group)
- Hands-on re-assembly of a double suction horizontally split case centrifugal pump. Rotor assembly, design variations and effects on reliability
- Wet versus dry types
- Installation pointers and application examples
- Double-Suction and Vertical Pumps (Rick Mathis, Pumping Machinery, LLC):
- Hands-on re-assembly of a double suction horizontally split case centrifugal pump. Rotor assembly, design variations and effects on reliability
- Open versus enclosed vertical lineshaft designs; repair techniques and upgrades; cavitation – how to avoid it and what to do about it if you can’t; reassembly of a small vertical pump and importance of impeller-to-case lift clearance for larger units; reverse engineering your pump installations for maximum reliability; bearing design configurations and materials for maximum reliability in “difficult” applications; OEM parts versus duplicates; materials selection for problem avoidance; common problems with vertical turbine pumps and what to do about them; sump design and submergence / turbulence considerations; register fits and clearances, lateral clearances and wear rings; foundation design and vibration – how to reduce
Lunch and Tour
11:30 a.m. – 1:00 p.m.
A tour of the John A. Walker Memorial Pumping Station (Merat Zarreii, F&T Division Manager, DeKalb County Department of Watershed Management)
All participants are invited to tour the nearby John A. Walker Memorial Pumping Station in DeKalb County. The original pump station was constructed in 1942 to allow DeKalb County to pump raw water from the Chattahoochee River to the Scott Candler Water Plant. This station originally had three DeLaval Split case horizontal pumps. In the early 1970's, three Peerless vertical turbine two-stage 1750 HP pumps were added. The new pump station construction is almost complete and includes innovations such as an automatic sand removal system, dual-flow traveling screens and six 2750 HP Goulds Vertical Turbine 60 MGD pumps.
Session 2: Bearings and Lubrications
(Steve Young, MRC / SKF Bearings and Roy Forson, Imerys Performance Minerals)
1:00 p.m. – 3:00 p.m.
Participants will learn about:
- Bearing failure modes (skidding, preload, overheating)
- Lubrication methods (grease, oil, mist)
- Fundamentals of lubrication
- How lubricants work
- Additives and what they do
- Oil analysis and interpretation
- EHL (elastohydrodynamic lubrication) and why it is important to bearings and gears
- Synthetic lubrication
- Proper lubrication of bearings and couplings
- Storage and handling of lubricants
Session 3: Alignment and Vibrations Fundamentals
(Mike Keohane, VibrAlign, and John Visotsky, Chairman of Vibration Institute, Atlanta Chapter)
3:00 p.m. – 6:00 p.m.
Session discussion will include:
- Fundamentals of alignment: straight edge, dial indicators, laser
- Pumping-to-pump alignment
- Motor-to-pump alignment
- Overall vibration level limits versus FFT spectral analysis; interpretation of amplitude-frequency versus amplitude-time wave form
- Field case examples
Reception
6:00 p.m. – 7:30 p.m.
CONFERENCE DAY 2—SEPTEMBER 21
Session 4: Positive Displacement Rotary Pumps
{Jim Brennan, IMO (multiple screw pumps), Colfax Pump Group; Todd Kierstead, Allweiler (progressing cavity pumps), Colfax Pump Group; Chad Wunderlich, Viking (gear pumps), IDEX Pump Group; and Gerald DaBoub, Boerger, LLC (lobe pumps)}
8:00 a.m. – 12:00 p.m.
Discussion topics will include:
- Three-screw pumps
- Progressing cavity pumps
- Gear pumps and their applications
- Design feature comparison and hands-on assembly work
- Viscous versus thin-fluid pumping
- Reliability and troubleshooting procedures
Lunch Presentation by Sponsors and Vendors
12:00 p.m. – 1 p.m.
Session 5: Mechanical Seals vs. Seal-Less Pumps
(Frank Huntington, John Crane Inc., and Bob Courtwright, Eagle Burgmann Industries)
1:00 p.m. – 4:00 p.m.
Huntington will provide an overview of mechanical seals and packings and will demonstrate through an actual hands-on exercise how to set a component seal and compare assembly procedures with a cartridge seal. His instruction will include information on both mag-drive pumps and canned-motor pumps.
