PUMPTEC-2012 PUMP CONFERENCE

Wednesday, September 12

8:15 – 8:45 Opening Address: looking for a candidate

8:45 – 9:30  Session #1 “End-Suction Centrifugal Pumps”: (Lev Nelik, Pumping Machinery, LLC)

o   Theory and hands-on, re-assembly of single-stage end suction ANSI centrifugal pumps. 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, troubleshooting methods, hands-on performance testing of two sample pumps operating in parallel mode and plotting performance curves

 9:30 – 10:30  Session #2 “Submersible (wet and dry) Pumps”: (John Ondrejack, Flowserve, Municipal Group, and Glenn House, Carter & Verplanck)

o   Hands-on re-assembly of a submersible pump. Rotor assembly, design variations and effects on reliability

o   wet versus dry types

o   installation pointers and application examples

10:30 – 11:30  Session #3 “High Pressure Pumps: Centrifugal (multi-stage) versus Reciprocating Considerations”: (Ron Hayes, Torishima Pumps and Jamie Baran, ClydeUnion Pumps)

o   Application and system considerations of selecting centrifugal versus positive displacement pump. Design variations and effects on reliability and energy

o   Horizontally-split, vertically-split multi-stage centrifugals

o   Minimum flow by-pass requirements

o   Boiler Feed applications at power generation plants, refinery and pipeline applications

11:30 – 1:30 Luncheon with a Tour:  a tour of Fulton County large Wastewater Plant and neighboring DeKalb County Municipality Raw Water Intake Pump Stations. Attendees will enjoy a tour to see the pumps, motors, controls and operation. Fulton and DeKalb new stations are brand new (300 MGD), and the old DeKalb station (190 MGD) provides a good comparison between old and new technologies. These stations are not far from the Conference Site and are on Holcomb Bridge Road and the Chattahoochee River. The original DeKalb pump station was constructed in 1942 to allow DeKalb County to pump raw water from the Chattahoochee River to Scott Candler water plant. This station originally had 3 DeLaval Split case horizontal pumps; later in the early 1970’s three Peerless vertical turbine two stage 1750 HP pumps were added. The new station has many innovations including an automatic sand removal system, dual flow traveling screens and six 2750 HP Goulds Vertical Turbine 60 MGD pumps.  

Organized by the Advisory Committee member, Mr. Merat Zareii, DeKalb County Watershed Management, and Kevin Miller, Fulton County Watershed Management.

1:30 – 3:15 Session #4 “Bearings and Lubrications” (Steve Young, MRC / SKF Bearings and Roy Forson, Imerys Minerals and Michael Litke, Timken Bearings)       

3:15 – 5:00 Sessions #5 “Alignment and Vibrations Fundamentals” (Mike Keohane, VibrAlign, and John Visotsky, Chairman of Vibration Institute, Atlanta Chapter)
