FLEXFLON WAS NOT NECESSARY
Liquids with enough lubricate, to use with vane pumps, infrequency need the chemical resistance of Dupont Teflon. Virgin Teflon is "dead" and unresponsive. Stiff and rarely deflects above 30Hz. The poor response characteristics, make it necessary to greatly over size the diaphragm. Oversizing provided so much liquid that on its own, it does half the job. Although the Flexorber LP does more work as a volumetric damper than a 5 litre accumulator it is a waste of money in this application. |

GOOD FOR VOLUMETRIC FLUCTUATIONS
Ideal for response up to 60Hz., and directing the spikes at the inside of the bladder, make 600% most cost effective than, for example, a PipeGuard, - PipeHugger still leaves a lot of noise in the system; though it does isolate pipe resonance from amplifying the pump signal. |

THE PROBLEM IS HIGH FREQUENCY PRESSURE PULSATION, "ACOUSTIC" NOT FLOW FLUCTUATION
WaveGuard can completely eliminate audible evidence of the 223 Hz. Frequency, for less than 40% of the cost of treating it as a flow fluctuation. |

The worst and most inexcusable error in pipe system design is to treat pressure transfer as the same as rate of mass transfer, & assume that liquid is incompressible. (or that speed of sound = infinity)
