Key characteristics of rubber bellows :
Function: Engineered for suction and discharge applications, they reduce stress on pumps and pipework. They compensate for misalignment and accommodate thermal expansion and contraction.
Material : The product is manufactured from a range of compounds including EPDM, NBR, CR), FKM and Silicone. This ensures that the product is both chemically resistant and flexible.
Design : These are typically molded in spherical form with reinforced fabric and metal floating flanges, such as single-ball or double-ball configurations.
Installation : The mounting of the tie rods is designed to prevent overstretching and withstand pressure thrust. To ensure correct installation, it is essential to verify the positioning of the retaining ring to prevent leakage.
Applications : This type of pump is widely used in cooling water systems, as well as in pumps, heating, ventilation and air conditioning (HVAC) systems, industrial piping and marine engines.
