Pulsation Damper for Motor-Driven Metering Pumps
Pulsation dampers have an equalising effect. They are used to ensure low-pulsation metering.
Product description
PVDF In-Line Pulsation Damper
Function: Hydropneumatic reservoir with deflection
The PVDF reservoir with PTFE diaphragm offers excellent chemical resistance, making it suitable for a wide range of liquids. The pulsation damper has two liquid connections and can be installed either directly in the pipe or diagonally across with a set of blanking plugs. Deflection in the fluid valve aims the volume flow directly at the diaphragm. This causes the volume flow to come into direct contact with the diaphragm. In this way the trapped gas volume optimally balances out fluctuations in the volume flow.
Please note: Only use pulsation dampers in conjunction with an overflow device with adjustable back pressure / relief valve.

The priming pressure is approximately 0.6 x the operating pressure. Maximum medium temperature, 65 °C. Connection parts must be ordered separately.
Filling of the reservoir with nitrogen takes place via the VG8 gas filling connector or with compressed air using a standard filling valve (e.g. a car tyre valve).
| Attention: | If using combustible liquids, nitrogen must be used as a filling gas. Do not use oxygen under any circumstances! |

PP In-Line Damper
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.
Please note: Only use pulsation dampers in conjunction with an overflow device with adjustable back pressure / relief valve.
Damper diaphragm is replaceable, seals made of EPDM.
Medium temperature max. 50 °C
Pre-pressure is approx. 0.6 x operating pressure.

Overview
For low-pulsation metering
Pulsation dampers are available in different versions: diaphragm accumulators, in-line dampers, bladder dampers and 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
