Constant pressure and flow with packed plunger pumps.
The high volumetric efficiency of the packed plunger pump, with minimal dead volume in the pump head, (unlike diaphragm head pumps) the level of pulsation is already small, and lack of lost motion reduces pressure shock generation, small flow thru, dampeners kill what remains. When applying plunger pumps at 1000 psi to 15000 psi, pressure pulsation interception is advisable.

1. PipeHugger
With liquid in the elastomer bladder and stainless wetted parts. A small dampener close to a pump is far better than a large dampener installed remotely. The general rule is, not more than 12 pipe diameters from dampener to pump and always a straight line, or not tighter than a 45 degree “L” or a 5D bend. Typically, Jacketed dampeners are purchased with system pipes radiating from a separate base block, from which the dampener capsule is released by removing 4 bolts, for minimum down time. The ability to cool the suction & so reduce the vapor pressure at the same time as removing suction acceleration head loss enables pumps to prime, that would otherwise not be able to run at all. PipeHugger and minimum dead space, plunger pump the most efficient and so smoothest of all reciprocating pumps. The large diameter of PipeHugger ensures pressure pulsation dissipation. Liquid in bladder, gas in drive bonnet enables low cost construction.

2. FlexOrber
LDi "FlexFlon" or DuPont Teflon diaphragms & stainless liquid chamber. Available with separate accumulator safety blocks to preserve system integrity during service and/or with heating/cooling jackets. PTFE compatibility diaphragms are offered in two forms: LDi “FlexFlon” or DuPont virgin Teflon backed with elastomer. The “FlexFlon” appears to have 4 times the life at 50% the cost.

3. PipeGuard
Gas in the bag, and an all stainless pressure vessel. For corrosive environments the complete pressure vessel is manufactured from stainless steel in accordance with ASME VIII code. The tall slim configuration enables volume at lower cost. The sacrifice of diameter is a loss of pressure pulsation damping efficiency. The “PakFram” HP hermetic metering pump, one twentieth the inefficiency of a diaphragm head, but the same safety.


Select fluid control pulsation dampeners for your system only after you know how to connect them
When you see pulsation dampeners, reciprocating pumps, rotary pump, or other hardware type of interest, request literature dedicated to that dampening subject ( 1-888-DAMPERS )

Pulsation dampeners are designed to address pressure pulsation, which is caused by the resistance of the system to flow. Therefore, our pulsation dampeners focus on the system related responsibility and are less related to pump liability.
PUMPS make FLOW, SYSTEMS cause PRESSURE, pressure pulsation is a system response, AND a system responsibility NOT a pump manufacturers liability.
