Pulsation Damper range called The PumpGuard with Flow Through Flex Tube.

PumpGuard pulsation dampeners that have 3" through 14" diameter connections, with stainless steel liquid contact metal parts at minimal cost.

Combined of pulsation damping and flow fluctuation smoothing capability, plus the straight line "clear-flow" path from in to out, makes the Pumpguard pulsation damper ideal for sludges, slurries, suspended particulate, and "food" liquids.

A Pulse Damper is capable of working at negative pressures without "hemorrhoiding", as well as use at elevated pressures. Used in flanged systems with ease of "as a spool piece" removal, for easy cleaning with a lance.

The ends are machined in accordance with ANSI B16.5 or EC "DN-PN" norms. having the flange face in corrosion resistant material. The face of the dampers has threaded studded bolt holes.

Socket head cap screws are equi-spaced between holding the end cover plate of the damper  to the end plug, which is retained by the segmental lock ring .

Integral seal beeds on the damper flextube ends, enable sealing by push in tubes a part of the stainless flange face component. This is preferable to leaking hose clamps.

The Flextube thickest point prevents both suck in, and blow out into the corner between end plug and shell. The Flextube gas support option that is perforated and has an internal cross, "collapse preventer", allowing use with high pre-fill pressures in the pulsation damper.

Flow Through Flex Tube Pulsation Dampener

For application to larger hose and peristaltic pumping systems.

Pulsation Dampener with Elastomer Gas Bag “Bladder”, the PipeGuard range.

Single connection versions of these pulsation dampers are for flow fluctuation reduction, PipeGuard pulsation dampeners however may have two connections flow through connection, direct ported for small sizes, or by piping base blocks for larger sizes; they can pressure wave dampen to some extent, but not as properly as the PulseGuard Inc. PipeHugger range of large diameter dampeners.

The benefit of the PipeGuard "dampeners" is that being small diameter, which of itself reduces their dampening efficiency, they are lower cost particularly for higher pressures, where the pressure shell of the pulse damper has to be stainless steel for external corrosion resistance reasons.

The damper Gas bag (bladder) is molded as one piece, Our gas bags (bladders) are not glued together.
Our gas bags (bladders) have an internal cushion corner to prevent their damage when bring compressed around their head plug. The PipeGuard range has gas bag (bladder) within which there are tension webs. These webs work in tension to ensure that the central end "anti-extrusion plate" aka "button" does not dangle free and off the center line, then fail to cover the liquid connections, and thereby allow the gas bag (bladder) to vomit down the liquid connection.

Pulsation Dampener with Elastomer Bladder

For saline atmospheres and corrosive environment, also high pressure.

Pulsation Dampeners for High Pressure with Elastomer Bladder, The PipeHugger HP.

Pulsation dampeners for smoothing industrial pipe systems, with flange face or, "O" ring & piping base.
For flow fluctuation and interception of system pressure waves in process fluids, that do not require the use of PTFE diaphragms.
Pulse dampener is safely closed by tamper-proof segmental lock rings that are retained by a set or boss on the end-plug, such that the ring can not be removed without first de-pressurizing the damper.
The ratios of dimensions with these "lock ring" Dampeners enable the safe depressurization of the energy contained in the cushion gas, prior to vessel 4:1 failure pressure point.

Cost saving with "liquid inside" the bladder dampeners only need the vessel shell, which house the inert Nitrogen pre-filled cushion, to be made from carbon steel.
This damper construction cost saving is spent on having a larger diameter. The large pulsation dampener diameter successfully attenuates pressure waves, generally traveling at 3600 mph, that are force into the dampener by the multi-port piping bases.
Pulsation dampeners designed with liquid in the bladder, only require a base plug, the liquid contact part, and the bladder, to be compatible with corrosive system liquids, as opposed to the entire vessel being high cost metals.

High Pressure Pulsation Dampeners with Elastomer Bladder

For process metering pump systems that do not ned PTFE.

Pulsation Dampeners Low Pressure series PipeHuggers with liquid inside an Elastomer Bladder

The Pulsation Dampener principle of operation & features of the "PipeHugger" liquid bladder are:
a large diameter chamber, relative to the diameter of an entry and exit hole to that chamber,
ensures that pressure pulses entering and attempting to pass through the chamber, die away , are dissipated.

The death of pressure waves is relative to a near "cube" law exponent, by distance from entry point to the damper to the nearest point for reflection.
Which means that a pressure wave, entering through a small hole into a pulsation dampener, finding itself in a chamber 12 times the diameter of the entry hole damper, will die away.
What is left of the pressure wave, then has to find its way out of the outlet form the damper, that process provides even greater dampening.

In combination this pulsation reduction effectively stops any pressure disturbance from traveling back up the suction line where it would breake the supply column if not dampened.

The bladder, that is the liquid chamber in the pipehugger type of pulsation damper, is large diameter.
Large diameter membranes are pliable enough to respond to low level pressure changes, so that these pulsation dampeners are both very effective flow fluctuation accumulators and pressure pulsation interceptor dampeners.

PipeHugger pulse dampeners are safely closed by tamper-proof segmental lock rings, that are retained by a step or boss on the dampener end-plug, such that the ring can not be removed without first de-pressurizing the damper of its pre-fill cushion gas spring.
The ratios of dimensions with these "lock ring" pulsation dampeners enable the safe depressurization of the energy contained in the cushion gas, prior to vessel failure pressure.

PipeHugger dampeners have an end face that is machined to an ANSi flange stud bolt pattern and a raised face.
Achieving flow through capability, these capsular dampeners are typically mounted on multi port base blocks. Thru-flo enable pressure pulse and transient spike interception.
Released from base block by 4 screws only minimizes down time and maintains pipe system integrity.

Low Pressure Pulsation Dampeners with superb flow smoothing ability and Elastomer Bladders.

For pump suctions systems to prevent loss of volumetric efficiency.
