Air Operated Double-Ended Diaphragm (A.O.D.D.) PUMPS
with Various PULSEGUARD Dampers

Pump 3 times father with no greater air supply, make flow as smooth as a turbine,
by installing:- Plastic or SS + Elastomer or Flexflon, dampers

Plastic + Elastomer gas bag, please go to the PIPEGUARD PLAS. range price list of off the shelf inventory items, dims. weights and drawing.
Below 40psi (Approx. 3BarG) the pressure used to drive a liquid of more than 50 cP into, to a halt, back out again from a "T" piece, leaves pulsation in the system.
If you want smooth flow below 40 psi, or to be able to flush your system, then always used a FLOW-THROUGH two connection pulsation damper.

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.

Stainless + Flexflon please go to the FLEXORBER SS/LP range price list of off the shelf inventory items, dims., Weights and drawing.

Single connection pulse dampers are also available, but flow-thru is standard single connection is more costly. You can always take a 2 connection and use one & the other for system drain.

Selecting Pulsation Dampeners for Different Pump Systems.
Flow through pulsation dampers are at least 3 times more efficient than T off line accumulators.
Dampeners that do, flow goes through, but pressure pulsation does not.
