Gas in Bladder Type Pulsation Dampeners

SMALL DIAMETER PULSE DAMPNERS Featuring

• FLOW STABILIZATION
  Are excellent flow fluctuation stabilizers.
  
  
• HIGH PRESSURE AT LOW COST
  "PipeGuard" "Slim Line" range dampeners are extremely competitive for high pressure application.
  
  
• FOR SALINE ENVIRONMENTS
  With full stainless steel construction are ideal for offshore oil and gas control sytems.
  
  
• GREATER INTEGRITY
  The gas bag "bladder" in this damper design is a seamless one piece molding; greatest compatibility and integrity.
  
  Common Elastomer Availability from MEMBRANO_FLEX Ltd. Div of LDI Ltd for you to choose from:-
  Information Source - edited from "KEVIN-TECH" aka Kevin Bebb's Technical Notes - LDI Ltd. in-house proprietary , since 1963. The compound ingredient percentages are chosen by LDI Ltd. to cause similar physical properties, and from advice by the Rubber& Plastics Research Association (aka RAPRA.) and others. :-
  
  In the uncured / un-polymerized state,: To be easily transfer-injectable over distances greater than 3x the item diameter, without the use of long oil alkids etc. for plasticization.
  
  In the cross linked / polimerized state, to have :-
  
  
  1. Elongation at break in excess of 600%
  2. UTS greater than 2000 psi (140 bar)
  3. IRH Shore "A" scale hardness 55-60
  4. Good compression set resistance for seal-points
  5. The use of "non-leaching" plasticizer - IE that crosslinks within the cured material
  6. No Sulfur
  
  MATERIAL TO CHOOSE FROM.
  Note - "LDI" are not compatibility engineers. Be sure to check your selection against the "O" rings Seal, gasket,valve diaphragm, pump packings that have proved satisfactory for your system.
  
  
• LONGER LIFE
  The anti-extrusion plate of this pulsation dampener can not jam like stem guided poppet valve.
