    • Analysis And Testing Of Alternative Bearings Materials For Applications In Sealless Pumps 
      Lorenc, Jerome A.; Nelik, Lev (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)
      As the usage of sealless pumps increases, so do the demands for journal bearing materials that can operate successfully through the thermal upsets that can take place in these pumps. Material specification literature is ...
    • Analysis Of The Thermal Behavior In The Sealing Cavity Of An Overhung Api Process Pump 
      Nelik, Lev (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)
      In recent years, cooling requirements for mechanical seals have become a subject of controversial opinions. While the maximum limiting temperatures of mechanical seals are known and specified by seal manufacturers, the ...
    • Effect Of Mechanical Unbalance On Vibrations, Forces And Reliability Of A Single-Stage Centrifugal Pump 
      Nelik, Lev; Jackson, Charles (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)
      The effect of rotor mechanical unbalance on pump vibrations was tested for a typical ANSI pump. It was found that significant damping of vibrations occurs at actual (wet) operations as compared to dry run. Rotor forces and ...
    • Infinite Dry-Running And Solids-Handling Via Combining Mag-Drive And Gas Seal Technology 
      Nelik, Lev; Miller, Chris L.; McGinty, Dave (Texas A&M University. Turbomachinery Laboratories, 2002)
      This paper presents installation and field experience of the barrier sealless pump design. Barrier design is a combination of a sealless mag-drive design and gas seal technology. Gas seal separates the fluid end from the ...
    • The Use Of Basic Hydraulics To Solve Field Problems: Three Cases 
      Nelik, Lev; Silvaggio, Joseph A.; Joseph, John P; Freeman, Jeffery (Texas A&M University. Turbomachinery Laboratories, 1996)
      Single stage double suction horizontally split pumps are widely used in cooling tower water applications. Their operational record varies depending on installation (sump and piping detail), mode of operation, speed, specific ...
