Product description
Pulse damper, also known as pulsation damper and pulsation buffer, is a common component to eliminate pipeline
pulsation and is a must-have accessory for metering pumps. It can smooth out pipeline pulsations and system
water hammer caused by volumetric pumps such as metering pumps and diaphragm pumps. It isolates the gas
from the liquid in the pipeline by a corrosion-resistant diaphragm, and smoothes the pipeline pulsation through
changes in the volume of the gas chamber.
Shell material: PVC, PP, PVDF, SUS304, SUS316L.
Diaphragm material: PTFE composite, FPM, EPDM, NBR

Volume selection of diaphragm pulse damper
Flow rate of the pump per hour ÷ 60 ÷ Number of strokes of the pump per minute x 15 = actual minimum required
volume of the damper
That is, multiply the metering capacity (ml) of each stroke of the metering pump (or diaphragm pump) by 15 to get
the minimum volume of the damper required to reduce the pulse by 90%. Note: (This calculation formula is
applicable to single-head pulse type pump body. )
Working principle
According to Boyle’s law P1V1=P2V2, the volume of gas is inversely proportional to the
pressure of the gas, and the pipeline pulsation is smoothed by changing the volume of the gas.
It has a sinusoidal system effect on the flow rate. At the wave peak: the volume of the air
chamber becomes smaller, and the pulse damper absorbs the excess flow liquid; at the wave
trough: the volume of the air chamber becomes larger, releasing the stored liquid, thereby
achieving a smooth pulsation effect.
