FOR HAZARDOUS & HIGH PRESSURE, MATCHED WITH DOUBLE LAYER "Flexflon" Dampeners that have secondary containment sealing, and hazard alert port option to between the layers.
Double Layer, Sandwich, 2 sheet PTFE DIAPHRAGM METERING PUMPS
A COMMON PROBLEM with diaphragm heads
Do they tell you to use a packed plunger pump if possible?
A negative pressure wave - shock - travels back up the supply system - at about 3000 miles per hour. They break the liquid column into slugs of liquid spaced with air and gas pockets.
Now the supply line feeds the pump intermittently, liquid gas liquid gas bubbles, "slush".
The pump efficiency falls further, has no chance to maintain any metering accuracy. Keep it simple, use plunger pumps, & simple dampeners .
After compressing and compressing the liquid, the velocity jump results in shock from jerking the mass from zero up to 3 times normal velocity, plus instantaneous decompression into the system. Shocks traveling faster than a bullet. The shocks may also amplify by resonation cracking the pipe.
THE HIGH VALUE ANSWER:
Shocks can not bypass - the dampener range FLO, & FL-LP for suction
REMARKABLE low cost RESULTS
1). Immediate return to the pump vendors 1% metering accuracy and often better.
2). Higher flow rates. The pump can now run 50% faster & transfer far more liquid.
3). Instruments and control systems function, and the pipe system stops fracturing.
