Tranquilizer : Pulsation / Surge Dampeners’

Surge suppressors for air-driven diaphragm pumps

This Warren Rupp Tranquilizer® is a completely automatic diaphragm fitted surge suppressor which reduces the flow and pressure pulsations in a pumping system characteristic of reciprocating many different type pumps.

Performance Criteria

  • Pressure: To 8.6 bar
  • Temperature: To 150 l/min
  • Viscosities: Highly viscous
  • Size: 0.5" to 3" 


  • Automatically self-charging and self-venting to maintain most efficient air cushion pressure
  •  Air cushion separated from product by flexible diaphragm which prevents product aeration
  • External visual indication provides constant evidence of performance
  • Automatically maintains a constant volume of air cushion for most effective surge suppression, regardless of pump pressure
  • Simple to install and attention-free
