Type BM32
The KSH Type BM32 concrete bushing (plastic sleeve) is designed to be embedded during the casting of concrete filter bottoms using lost formwork—meaning the formwork isn’t removed after casting. The sleeve establishes accurate openings and receptacles for filter nozzles within the filter base. Its length is fully customizable to suit the required base or soil thickness. Manufactured by KSH Germany and supplied exclusively in New Zealand by Absorb It Ltd, the BM32 ensures you achieve both precision and long-term reliability in your filtration systems.
