Drawing on over thirty years of experience, Flo-Dyne Limited design and supply customised solutions for industrial silencing, pulsation dampeners, diffusers and surge equipment to control noise and pulsation in moving gases and liquids. Our established range of fluid control equipment meets all the specialised demands of the international market place including the statutory and regulatory requirements of the Pressure Equipment Directive (PED 97/23/EC). In the case of products for the UK water and sewage industries an installation and commissioning service has been developed.

The Company operates from its head office at Chesham where the technical design work is undertaken. The Directors, Engineers, Projects and Inspection personnel have been involved in the fluids industry for a number of years and have a wide experience covering the design, production, installation and commissioning of the control equipment.

Used extensively throughout the world by gas, water, power, chemical and processing industries, our equipment provides cost effective solutions that deliver guaranteed results.

Product Information

Vent Silencer

A Vent Silencer for safety relief and atmospheric duties

The Flo-Dyne Vent Silencer is used to reduce unwanted noise from vent or safety relief lines and stacks that discharge to atmosphere. Gases handled include steam, oxygen, carbon dioxide, air, nitrogen, as well as natural gas and the many process gases used in industry.

Construction utilises our experience from building pressure vessels to build a robust piece of equipment that can withstand high temperature steam, high inlet velocities as well as significant local loads from wind, earthquake and pipe work expansion. Full penetration welds are used throughout the construction using ASME qualified welders.

The inlet diffuser is built like a pressure vessel and receives the full force of the incoming flow. Strength is important to prevent disintegration and erosion under continuous and cyclic operating conditions. Flo-Dyne diffusers are built from standard pipe sizes or rolled from heavy-duty perforated sheet.

The internal acoustic core is built using long strand glass fibre and will withstand temperatures up to 800 deg. F; for higher temperatures, mineral or ceramic fibres are used. Main shells are constructed from steel boiler plate; for high temperature duties stainless steels or high alloy steels are used and for low temperature duties stainless steels are used. Internal construction will utilise corrosion resistant Corten, carbon steel or 300 series stainless steel for the perforated baffles with the acoustic pack designed to accommodate thermal expansion to give stress free operation.

Equipment may be self-supporting or supplied with pad or cradle type supports. Installation orientation may be either vertical or horizontal with no change in performance.

Liquid Pulsation Dampener

An inline device to eliminate pulsation and reduce maintenance in power pump discharge lines.

The Flo-Dyne Liquid Pulsation Dampener reduces discharge pressure pulsation by approximately 75%. Actual performance depends on the type of pump, connected piping system and liquid handled.

The spherical shape is the strongest arrangement for pressure-containing service … up to 6000 psi, design pressure is standard.

Maintenance free, the dampener can be permanently welded in the line, saving flange costs and potential flange leaks. Inline configuration eliminates special support problems

Completely liquid filled, with no moving parts, this dampener removes the maintenance and gas charging requirements.

The stationary internals guide the incoming flow into a rotating path within the spherical shell. The spinning liquid mass creates a system smoothing/flywheel effect. Viscous drag on the sphere walls and the capacitance effect of the relatively large volume located next to the pump further help to dampen pressure pulsation.

The dampener is all steel construction, with no bladders to fill or replace and virtually no temperature limitation. With nozzles bevelled for weld, the unit becomes a part of the piping. Construction may be in carbon steel, 300 series stainless steel or a variety of duplex and super duplex steels.
