An Inlet Pressure Stabilizer (or Captive Acceleration Tube) is used to maintain consistent inlet pressure to the pump. The internal flexible tube absorbs energy from a pressurized feed which maintains a consistent pressure and flow through pump inlet. Having consistent inlet conditions will improve pump performance and reduce the risk of cavitation.
To properly install the Inlet Pressure Stabilizer two adapters are required. These should be the same size as the pump inlet or one size larger.
