Pulsation Dampeners for Multiplex Power Pumps

How to ensure lowest in place cost and most performance by standard installation methods. Halving the cost and tripling the performance of pulsation dampening multiplex power pumps. Power pumps are frequently used for fluid power hydraulic oil purposes.

Triplex, Quituplex, Septuplex "power pumps" And Pumps supplied to API 674 with PulseGuard Pulsation Dampeners"pulsation suppression devices".

For long life of system components, ex. RO membranes and a multiplex pump always specify a no moving parts WaveGuard (WaG-Cer) – ceramic balls, vertical self-draining
When pipe length natural shake rate = pump RPM the result is pulsation
Pipe line, high pressure response pulsation and resonance.
Pump flow induced fluctuation only.
The before and after oscillograph traces were taken from a deep hole boring machine, the pumpage was cutting oil. The problem was that the pressure pulsation caused cutting tool “chatter” and showed up as bad surface finish and less than 20% life of the ceramic/carbide cutting tool tips.

WaveGuard guards against pressure wave generation. For piping systems 3” through 12” diameter. WaveGuard's have no moving parts and no foam to clog and degrade The WaveGuard disperses pressure transients over a longer time base, and reduces their amplitude. WaveGuard's are not flow fluctuation accumulators.

PumpGuard guards against suction cavitation (suction stabilizers). For pipes 3” through 12” diameter. PumpGuard's have no nitrogen or air pre-fill or “precharge” requirements. Wherever possible use a bend with radius not less than 5 pipe diameters – 5D bend. The PumpGuard is a method of providing for pump instantaneous suction needs in large supply pipes without acceleration head loss. Losses occur from attempts to cause instantaneous flow reversals in a single connection.

Pulsation Dampeners for Multiplex Power Pumps Discharge pulsation often comes from poor suction conditions.
Liquid side up stops bubbles collecting.
PipeHugger up to 3” pipe is the ultimate in high frequency negative transient prevention; stops suction side bubble generation.
Pulsation is dissipated by large ratio or connection diameter to dampener diameter.

Tall and slim PipeGuards are a low cost method for externally corrosive environments since 1965. PipeGuard guards against pipeline fatigue.
*Pressure pulsation, travels through out a system at near 4000 mile per hour, say 300 times faster than flow velocity.
Catching pressure waves traveling faster than the fastest bullet requires intercepting them.
PipeGuard TW series “flow-through” dampeners have intercepted pressure pulsation since 1965, and are proven 300% more efficient than copies with only one connection. And 250% better than copies with add on false flow through bottoms.
A ‘septuples” reciprocating 7 plunger pump with each 180 degrees of displacement being overlapped by 128 degrees has no flow fluctuation but lots of valve interaction.
System response to valve interaction is a major cause of high frequency pressure pulsation.

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.
