Liquid in Bladder Type Pulsation Dampeners
LARGE DIAMETER DAMPENERS for Low Pressure and Suction Featuring
ACCELERATION HEAD REMOVAL
First class for addressing suction acceleration head. The separate
inlet port allows continuous flow, while the seperate outlet to a
pump provides the jerking flow without the need to lose pressure (k)
by having to accelerate the entire supply line.
PRESSURE LOSS SAVING
The lack of reciprocation up and down a single connection produces
much less pressure pulsation than non flow-through designs.
LOWER COST COMPATIBILITY
Suitable for difficult to handle liquids because only the base plug
and anti-extrusion plate become wetted, small amounts of Aloy 20,
Hasteloy, Titanium, even Zircomium will complete the damper
Cavitation reduction by instant filling of pump chambers stops
negative pressure from running back up the supply line, and breaking
the fluid column, which is the normal reason for pump knock.
HIGH FREQUENCY INTERCEPTION
High Frequency pulsation , and acoustic resonse from the lengths of
the piping is intercepted by the LP Pipehugger range just as
efficiently as in the High pressure Pipehugger damper.
LARGE DIAMETER DAMPENERS for High Pressure and High Frequency Featuring
Are best at dampening pressure pulsation as a pressure spike
entering a large diameter chamber from a smaller hole, dissipates
before it can reflect from the vessel wall.
The greater dimension provides area for separate inlet outlet
conections - this gives in-line flow-through pulse interception.
Interception ensure the response that dampens the pulsation.
The bladder has liquid inside, the process fluid does not contact
the shell, the shell is available in low cost epoxy coated carbon
Thoroughly suitable for sludges and slurries, and solids carrying
applications. When the bladder flexes it shakes all particulate
loose - it is not packed into a "cake" against the damper wall, as
in gas bag dampners.
- PULSATION IS DIRECTIONAL
Full 180 degrees flow direction change causes all transients to
impinge on the flexible membrane.
