• Series PC-35

    The PC-35 Pump Connectors are designed specifically to reduce and isolate noise and vibration from pumps and other operating equipment. Available with working pressures up to 300 psi, and all types of elastomers including Teflon lining, these connectors are widely used in various industries from mining to food processing.
    PC-35 style Pump Connectors also come in eccentric and concentric taper types. Contact EVR for information on the many size variations available. Pump Connectors must be protected from axial piping movement by using pipe anchors or control units as required.

  • Control Units


    Expansion joints and pump connectors are not designed to support weight or limit pipe movement. Excess movement may be the result of abnormal temperature fluctuations, pressure surges, or insufficient anchoring or guiding of the piping. Where these situations occur, control units must be used to limit the amount and direction of movement to within the design limits of the flexible connection.
    Control units consist of adaptor plates which are bolted to the back of the mating pipe flanges. These plates are connected by a tie rod which limits the axial extension. In cases where excess compression is anticipated, an optional sleeve is fitted over the tie rod to limit movement in both directions. The minimum number of control rods needed in a control unit is two; however depending on size or pressure, more may be required. The chart below can be used to determine the requirements for your application.

  • Series CJ-31

    For situations where piping diameters of different sizes must be connected, EVR's CJ-31 tapered connectors are the answer. Manufactured to the stringent standards of EVR's product lines, these units can be engineered for specific material situations and offer all of the advantages of EVR's other expansion joints.

    In systems with load stresses, settling and equipment wear, misalignment frequently results. CJ-31 provide superb insulation from the vibrations of equipment, thus reducing the surrounding noise levels and protecting adjacent equipment from unnecessary wear and tear.

    With full face flanges, the Series CJ is retaining rings transmit the force from the torqued flange bolts to the mating flange, thus providing a perfect seal.

  • Series EJ-41

    For situations where piping diameters of different sizes must be connected, EVR's EJ-41 tapered connectors are the answer. Manufactured to the stringent standards of EVR's product lines, these units can be engineered for specific material situations and offer all of the advantages of EVR's other expansion joints.

  • Series DF/DB  - Rubber Connectors

    Features
    • Relative light weight
    • Non-conductive
    • Abrasion and corrosion resistant
    • High fatigue resistance
    • Wide material selection
    • Movement achieved with relatively low force


    Flue Duct Connectors are designed to absorb thermal movements and vibrations in industrial duct work. They are designed to handle hot corrosive gases found in industrial ducting systems and eliminate vibration cause by equipment such as fans, scrubbers, and mechanical dust collectors.

    DF-01 Flue Duct Connectors can be constructed either flanged or belted in various sizes, shapes and configurations for easy installation in any type of duct. Insulation pillows can be included for certain high temperature applications. Baffles are required where the gas stream contains particulates which might abrade the inner surface of the joint. Square, rectangular or round shapes can be produced in any size.

  • Series DF-60 - Rubber Connectors

    Features
    • Relative light weight
    • Non-conductive
    • Abrasion and corrosion resistant
    • High fatigue resistance
    • Wide material selection
    • Movement achieved with relatively low force


    Available in round or rectangular configurations, the DF-60 is designed for use in duct systems where pressure, abrasion and mechanical movement preclude the use of conventional ducting connectors. The external metal reinforcement and high strength synthetic reinforcing fabrics allow working pressures in excess of 25 PSIG. The wide arch design and rounded corners of the rectangular style allow for high movement capabilities while reducing fatigue due to flexing. Abrasion resistant rubbers allow the use of this expansion joint in applications such as discharge chutes, pneumatic conveyors and vibratory feeders. EVR DF-60 Expansion Joints are available in a wide range of elastomers and fabrics to suit most corrosive and temperature environments up to 400°F.
