8:15: Opening Address: U. Landau, Minister of Infrastructure (Israel), and Binyamin (Fouad) Ben Eliezer, Minister of Industry (Israel)

8:30 – 11:30  Session #1   “Centrifugal Pumps”    

·        End-Suction: Dr. Lev Nelik, P.E., Pumping Machinery, LLC, (USA/Israel) – Focus on Efficiency and Energy Savings

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, performance testing of two sample pumps operating in parallel mode and plotting performance curves 

·        Double-Suction: Haim Shlomo, Siniaver Pumps (Israel) – New hydraulics to improve operation

o   Hands-on re-assembly of a double suction horizontally split case centrifugal pump. Rotor assembly, design variations and effects on reliability 

·        Verticals: Gabi Klein, Gennady Heifetz, Michael Benjamin, Mekorot / EMS Shaham (Israel) – Maintenance Issues and Challenges for Proactive Maintenance Approach

o   Open versus enclosed 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

           

11:30 – 12:15: Special Presentations (4 sets of 10-minute-segments by the Conference Sponsors)

12:15 – 1:00: Lunch

  

1:00 – 3:00 Session #2 “Abrasive, Corrosive and Specialty Applications”

·         Abrasive Pumping Challenges: Menahem Weiss, Dead Sea Works (Israel)

·         Boiler Feed Pump Aspects for Power Generation: Marchel Kalmanovich,  Israeli Electric Corporation (Hevrat Hashmal)

  • Chemical Issues with Pumps: Boris Rechtman, ICL Chemicals (Israel)

                         

3:00 – 6:00 Sessions #3 “Electrical Aspects: motor efficiency, VFD, controls, and line losses: Oscar Heinhorn, Enercom Engineering (Israel), Mario Berman, Israel Electric Corporation, and Arik Dan, Yaskawa (Japan)

·         Motor-to-pump alignment effect on motor operation

·         Overall vibration level limits versus FFT spectral analysis; interpretation of amplitude-frequency versus amplitude-time wave form

·         Field case examples and examples

12:30 – 1:15 Lunch

  

1:15 – 3:00 Session #6 “Mechanical Seals versus Seal-Less Pumps”: Yossi Avisar, Laor Engineering (Israel), and Rammy Shellef, Ettem Seals (Israel)

Overview of mechanical seals and packings; actual hands-on exercise of setting of a component seal and comparing with a cartridge seal assembly procedures

·         Mag-drive pumps

·         Canned-motor pumps

 

3:00 – 4:00 Session #6 “Vibration Analysis for Rotating Machinery”: Dr. Leonid Avrukh, PMME (Israel), Shmil Shamis, Israeli Electric Hevrat Hashmal, and Dr. Elia Schwartz , Predictive Systems Engineering (Israel)

Various methods of vibration detection, interpretation and problem solving. Effect of unbalance, misalignment, blade-pass frequencies, and other factors are discussed. Mechanical, electrical and other methods applied and compared. Overall vibrations, FFT Spectral signatures, route planning and diagnostics. Field cases with examples are presented.
