Liquid in Bladder Type Pulsation Dampeners

LARGE DIAMETER DAMPENERS for Low Pressure and Suction Featuring

• ACCELERATION HEAD REMOVAL
  First class for addressing suction acceleration head. The separate inlet port allows continuous flow, while the seperate outlet to a pump provides the jerking flow without the need to lose pressure (k) by having to accelerate the entire supply line.
  
  
• PRESSURE LOSS SAVING
  The lack of reciprocation up and down a single connection produces much less pressure pulsation than non flow-through designs.
  
  
• LOWER COST COMPATIBILITY
  Suitable for difficult to handle liquids because only the base plug and anti-extrusion plate become wetted, small amounts of Aloy 20, Hasteloy, Titanium, even Zircomium will complete the damper construction.
  
  
• PREVENTS CAVITATION
  Cavitation reduction by instant filling of pump chambers stops negative pressure from running back up the supply line, and breaking the fluid column, which is the normal reason for pump knock.
  
  
• HIGH FREQUENCY INTERCEPTION
  High Frequency pulsation , and acoustic resonse from the lengths of the piping is intercepted by the LP Pipehugger range just as efficiently as in the High pressure Pipehugger damper.

LARGE DIAMETER DAMPENERS for High Pressure and High Frequency Featuring

• PULSATION DISSIPATION
  Are best at dampening pressure pulsation as a pressure spike entering a large diameter chamber from a smaller hole, dissipates before it can reflect from the vessel wall.
  
  
• ASSURED RESPONSIVENESS
  The greater dimension provides area for separate inlet outlet conections - this gives in-line flow-through pulse interception. Interception ensure the response that dampens the pulsation.
  
  
• COMPETITVE HOUSINGS
  The bladder has liquid inside, the process fluid does not contact the shell, the shell is available in low cost epoxy coated carbon steel.
  
  
• PARTICULATE SUITABILITY
  Thoroughly suitable for sludges and slurries, and solids carrying applications. When the bladder flexes it shakes all particulate loose - it is not packed into a "cake" against the damper wall, as in gas bag dampners.
  
  
• PULSATION IS DIRECTIONAL
  Full 180 degrees flow direction change causes all transients to impinge on the flexible membrane.
