Innovative new through bore hydrant from Saint-Gobain PAM UK delivers a durable and cost effective solution to water companies


Iron technology leader Saint-Gobain PAM UK, part of leading materials group Saint-Gobain, has added a new through bore CE fire hydrant, DN80 PN16, to its range of market-leading ductile iron below-ground hydrants.

Exclusive to Saint-Gobain PAM UK, the innovative new fire hydrant is the first through bore to be kitemarked to BS750:2012 and BS EN 14339, providing assurance of long term durability and security. The new hydrant, which provides a direct unobstructed full 80mm bore access to the pipeline when the outlet has been removed, has two main applications – access to the water mains for the fire service and for inspection, repair and maintenance activities. It is patent protected and is similar in design, installation and operation to existing hydrants, minimising the need for operator retraining.

Incorporating an array of technologically advanced features, the robust through bore fire hydrant has been developed as a low weight, compact design for ease of handling and installation. It has significantly increased flow rates at a low operating pressure, a maximum operating temperature of 60°, a safety factor of 2.6 and requires minimal maintenance. Additionally, it incorporates an automatic frost valve which prevents water escape during operation. Maintenance is enhanced through the hydrant’s secure bolted bonnet.

The hydrant has a universal inlet flange, stainless steel bolts and a 2½” London round thread stainless steel outlet (BS750:2012) are supplied as standard. All non-metallic parts are WRAS approved. Outlet options available are PN16 (standard), Bayonet (UK or Dublin) and N.I. Belfast. Other parts and accessories are available upon request.

Linda Wardle, Product Manager of Saint-Gobain PAM UK, commented: “This new and competitive through bore CE fire hydrant has been developed to meet the market’s increasing demand for innovative ways of accessing pipelines. It incorporates a number of design enhancements to ensure optimum durability and efficiency together with minimum maintenance. These attributes help reduce our customers’ total installed cost and future maintenance spend.”
