Rubber Bellows are primarily used on pumps, chillers and other machinery to reduce noise and vibration. Bellows terminology Tied or Untied relates to whether a rubber bellows is fitted with oval flanges and restraining tie bars (Tied) or is supplied unrestrained with loose swivel round flanges (Untied). Tied units are designed to stop the bellows from elongating and prevent the pressure thrust being transmitted onto the pumps and associated pipework.
Both Tied and Untied Units are suitable for a maximum operating pressure of 16 bar (at ambient temperature). As with any other unrestrained expansion joint, rubber bellows will extend under pressure.
Connection: Flanged PN16.
Pressure: 16 Bar Rated.
Approvals: CE Approved.
Temperature: -20°C to +100°C EPDM. -20°C to +80°C NBR.
