Overview
For low-pulsation metering
Pulsation dampers are available in different versions: as in-line dampers and as accumulators.
Pulsation dampers are used for low-pulsation metering and to reduce the flow resistance with long metering lines. They are also ideally suited to viscous media. The gas cushion between the housing and hose is compressed when the metering pump has a pressure stroke, at the same time as a partial volume of the medium is metered into the metering line. The overpressure that forms in the gas cushion causes the compressed volume to be transported on at the following suction stroke and the original, relaxed volume of gas is present again
Your benefits
- Low-pulsation metering
- Reduces flow resistance with long metering lines
