DT Active Pulsation PE PTFE Dampener

DT Series Active Pulsation Dampeners

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.

DT Series Active Pulsation Dampeners Operating Principle

DAMPENERS OPERATING PRINCIPLE

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.

Features & Benefits of DT Series Active Pulsation Dampeners

Dampeners features and benefits

  1. Minimise vibrations and water hammer effects
  2. Protect all kinds of instruments in your pipework
  3. Optimise pump performance and reduce maintenance costs
  4. Requires no pre-charging
  5. Modulates itself to the system requirements and pump performance unlike standard dampeners.
  6. More compact and modular unit which can be easily integrated into pipework systems or supplied built onto pumps to reduce the footprint even further.
  7. 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
