Text of Suction Stabilizers for Pulsation Control

  1. 1. Performance Pulsation Control Suction Stabilizers We put performance in our products
  2. 2. Why Suction Stabilizers? Pulsation Problems Start on the Suction Side! Appendage and Flow-Through Available Minimize pump cavitation Increase useful life of fluid-end parts Reduce cost of system ownership Cavitation can cause 10X the standard pulsations normally produced = less pump life! Operators look for discharge dampener failure, but unstable suction is typically the root cause Suction Stabilizer
  3. 3. Why Suction Stabilizers? Definitions Ha = (LVNC)/gxk = Acceleration head = Actual length of suction line = Average liquid velocity in suction line = Speed of pump crankshaft = Constant depending on pump type = Gravitational constant = Constant depending on fluid compressibility Ha L V N C g k Acceleration Head Loss Formula Flow-Through suction stabilizers isolate the pump from the remainder of the suction line = dramatic reduction of L line impact and overall less Acceleration Head Loss
  4. 4. Why Suction Stabilizers? = Atmospheric Pressure = Vertical distance from liquid surface to the pump centerline = Friction losses in suction piping = Acceleration head at pump suction = Absolute vapor pressure of liquid at pumping temperature Pt Hz Hf Ha Pvp Definitions NPSHa = Pt + Hz Hf Ha + Pvp NPSH improved through reduction of Acceleration Head Loss
  5. 5. Suction Stabilizer Performance
  6. 6. Common Stabilizer Solutions Simple Gas Cap Tanks Gas pocket above fluid column Gas Charged Stabilizer with gas cartridge requiring maintenance or replacement upon failure. Maintenance-Free Flow-Through Virtually no maintenance required. Suction Cellular Stabilizer Reactive Stabilizer
  7. 7. Suction Stabilizers Gas Cap Gas Cap or Stand Pipe or Air Tank designs are seldom maintained Gas cap rapidly absorbed by fluid = Elimination of effect and cavitation introduced
  8. 8. Suction Stabilizers Gas Charged Gas-Charged units separate the gas from the fluid via a cartridge, bladder, or cellular membrane = No gas absorption; More stable performance; Improved pump efficiency Requires cartridge charging and replacement
  9. 9. Maintenance Free Cellular Suction Stabilizer Virtually no maintenance required = low life $ cost Flow-Through Reduces Cavitation
  10. 10. Cellular Suction Stabilizer Maintenance Free
  11. 11. Flow Through Suction Reactive Stabilizer Virtually eliminates Acceleration Head/Pressure Loss Applicable to harsher fluids and higher temperatures Promotes acoustic isolation Consistent performance over a broad range of pressures Maintenance Free
  12. 12. Flow Through Suction Reactive Stabilizer Maintenance Free Maintenance Free Vertical Tank Suction Reactive
  13. 13. Things to Remember Suction Stabilizers - Critical to your fluid delivery and ultimate discharge performance Discharge Dampeners Reduction of acceleration and flow-induced pulsations Maintenance Free Options Initially more expensive, but long-term costs lower PPC Value Worry-Free Customer Experience Durable, High-Performance Solutions Engineering expertise to customize designs and predict pulsation performance Expert project management for a worry-free customer experience
