What makes DT Active Pulsation Sanitary Dampener Different?

The Tapflo DT Active Pulsation Sanitary Dampener has been designed in particular for the food, beverage, pharmaceutical and cosmetic industries where cleanliness and a sterile environment are necessary. The dampener is designed and prepared for cleaning and sterilisation in place (CIP and SIP). The DT Active Pulsation Sanitary Dampener is automatic cleaning and disinfection procedures implemented in these industries so it is essential that our products are prepared to comply with these procedures. Dampeners made of stainless steel AISI 316L, electro-polished and offer great mechanical strength combined with good chemical resistance. AISI 316 is resistant to aggressive and abrasive liquids. The dry part of the dampener that does not come into contact with the pumped product is, as a standard, made of corrosive resistant PP. ATEX rated Metal Dampeners are also available. They are supplied with earth connection and conductive materials: conductive body, diaphragm in PTFE (conductive backing) or EPDM (conductive).

DT Series Active Pulsation Dampeners

The Tapflo DT Series Active Pulsation Dampeners are the most efficient way to remove pressure variations on the discharge of the pump. The Tapflo pulsation dampener works in tune with the diaphragm pump it is fitted to, automatically setting the correct pressure to minimize the pulsations. The DT Pulsation Dampeners are available for all Tapflo pump sizes and material versions.

  • Minimise vibrations and water hammer effects
  • Protect all kinds of instruments in your pipework
  • Optimise pump performance and reduce maintenance costs
  • Requires no pre-charging
  • Modulates itself to the system requirements and pump performance unlike standard dampeners.
  • More compact and modular unit which can be easily integrated into pipework systems or supplied built onto pumps to reduce the footprint even further.
  • Can be supplied with numerous options such as:
  • BSP / NPT / Sanitary / Flanged Connections
  • Baseplates or Anti-Vibration Feet
  • Back-Up Diaphragm & fitted Guardian System
  • Housing Reinforcement Plates
  • Fitted to pump on a trolley

The air pressure supplied to the dampener is the same as the one supplied to the pump. When the pressure in the piping system decreases, due to the pulsating nature of the pump operation, the pulsation dampener supplies extra pressure to the discharge between the pump strokes, therefore supplying a steady flow of pumped medium. This pumping action created by the dampener, decreases the pressure variations and pulsations.
