Pulsation Damper for Motor-Driven Metering Pumps

Pulsation dampers have an equalising effect. They are used to ensure low-pulsation metering.

Product description

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.

The benefits for you

  • Low-pulsation metering
  • Reduces flow resistance when using long dosing lines

Accumulators

Pulsation dampers with separating diaphragm / bubble for providing separation between the gas cushion and metered chemical are used for low-pulsation metering as well as for reducing the flow resistance in long metering lines and with viscous media. The preload pressure of the gas cushion should be approx. 60-80% of the operating pressure.

Important: A pressure relief valve should always be fitted with an adjustable back pressure valve when using a pulsation damper.

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 pipework 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.

For Sigma metering pumps up to 370 l/h, DN 25.

Important: The pulsation dampers should always be protected by a relief valve.

The preload pressure is approximately 0.6 x the operating pressure. Maximum medium temperature 65 °C.

Connectors must be ordered separately.

The reservoir is filled with nitrogen via the VG8 gas filling connector or with compressed air using a standard filling valve (e.g. a car tyre valve).

Important:If using combustible liquids, nitrogen must be used as a filling gas. Do not use oxygen under any circumstances!
