Pulseguard

Preventing pulsation caused by the mass of a liquid system

Pulseguard Product Range

A Pulsation Damper is a liquid pressure container that reduces pressure variations and flow fluctuations . The container is often divided in to two sides by a flexible membrane, diaphragm, bladder, flextube, one containing compressibe nitrogen gas, and the other side through which the liquid goes; in the process the liqid pressure and flow variations are reduced or “dampened”.

PipeGuard

PipeGuards are generally manufactured using a stainless-steel body and end closure however PVC, Carbon Steel and Duplex along with many more alternatives can be used depending on the requirements of the customer.

FlexOrber

Flexorber (high pressure) and ShockGuards (low pressure): The Largest chamber diameter to port hole ratio (best high frequency pulse interception with flow velocity smoothing). Both types of damper work in the same way but are manufactured differently.

What is a Pulsation Damper ?

A Pulsation Damper is a liquid pressure container that reduces pressure variations and flow fluctuations .

Where does Pulsation come from ?

Pulsation is caused by the mass of a liquid system being accelerated and decelerated by a pumping action, or the repeated opening and closing of a valve.

The most exaggerated form of pulsation comes from simplex diaphragm type “metering” pump systems. Lesser pulsation is seen when duplex pumping . Triplex pump piping experiences even less pulsation.

Why is a Pulsation Damper necessary ?

In a metering system constant flow is normally required. A damper is essential to reduce the flow fluctuations to ensure process control and mixing.

In pipes pressure pulsation will shake the piping and dampening the pulses prevents fatigue and connection failures. In general removing pulsation reduced the energy usage to transmit liquid over distances and closing of a valve.

Where is a Pulse Dampener installed ?

For best performance a Pulsation Dampener should be installed at the start of the pipe down which the flow has to be forced or when the dampener is to perform as a suction side acceleration head loss reducer, then the installation is after the suction supply line at the entry to the pump inlet check valve.

Generally a pulsation dampener is installed as close to the source of the pulsation as possible.
