Flexible membrane accumulators neutralize water hammer effect in pressurized liquid containers

For companies involved in the distribution of pressurized liquids, the French company Pronal has developed a flexible membrane accumulator that neutralizes the effects of excess pressure in pipes, particularly at the valves. Designed to eliminate the water hammer effect caused by pressure differentials when liquid flows through pipes of decreasing dimensions, the product helps to prevent damage in distribution circuits. The accumulators can be used for hydrocarbons distribution in refineries and service stations and in drinking water supply networks, as well as in chemical plants, food processing facilities, and with pollution control equipment.

Each membrane is designed and manufactured to measure according to the exact requirements of the container in which it is fitted. Made from polyurethane or special rubber, the bladder accumulator possesses exceptional mechanical properties. These include strength, flexibility, homogeneity, high expansion capacity, and excellent tolerance towards toxic products.

All membranes are resistant to liquid chemicals, oils and hydrocarbons, are fully sealed and thus avoid all contact between liquid and tank. They vary in capacity from a pint to 3,200 gallons, withstand continuous temperatures up to 176 degrees Fahrenheit, and pressures up to 20 bars, depending on the application. The company is seeking business contacts in both Canada and the United States.
