Flexible Connectors, Expansion Joints

  •  

Our new stainless steel offering is engineered to provide superior quality and performance on all products.

More interesting designs are the threaded SFU through 2”, the double sphered flanged SFDEJ thru 12”, as well as the single sphere SFEJ through 24” diameter. These connectors are not ore reinforced; they are constructed of multiple plies of Kevlar tire cord and EPDM in a manufacturing process very similar to the manufacture of truck tires. This construction enables these connectors to breathe volumetrically and to be rated for maximum elongation so control rods are not necessary. We have been involved in intensive testing of these connectors through acoustical firms such as Cerami & Assoc., to verify that they are extremely effective in reducing both noise and vibration at pump impeller frequency (rpm times number of blades). We believe that we are the only firm that has developed this sort of acoustical data. The change to Kevlar, EPDM and captive flanges has virtually eliminated all failures.
