A.O.D.D. Pump Plastic Pulsation Dampener with PTFE Diaphragm

For your PTFE compatible applications we offer LDi FLEXFLON, which is PTFE that has been remelted and molded to provide flexibility without an elastomeric backing.

FLOW FLUCTUATION SMOOTHING On an A.O.D.D. Pump with Flexflon Diaphragm

Simply How it works:

1. Flow rarely goes above 15 MPH/24 KPH. There is time for it to go up a single connection come to a halt, and flow back out again, to keep the liquid moving whilst the pump is changing from one stroke to the next.

2. By smoothing the flow in this way, the pump does not have to generate pressure peaks to accelerated the liquid with each stroke.

3. Flow smoothing reduces the pressure pulsation a pump must create to overcome the resistance that your system has caused.

4. The response of your system to the residual level of flow fluctuation, is usually at a higher frequency, and travels as pressure waves at typically 3500 MPH/5600 KPH.

5. To address pressure wave pulsation, intercept this pressure pulsation with flow-through pulsation dampeners . ("See Pressure Pulsation Damping")

This, single connection approach to flow smoothing, requires the use of a "t" piece. This method does not ensure in place flushability for service technician protection. Use of a flow smoother with a single connection, can not guarantee pressure stability, [or at all above 10 Hz] without first having made a system pipework, etc. analysis.
