GEMÜ Multiport SUMONDO combines several individual single-use diaphragm valves in one multi-port valve block, offering a new solution for applications in pharmaceutical and biotechnological industries. The tried-and-tested GEMÜ SUMONDO diaphragm valve principle ensures hermetic separation between the actuator and the medium by welding the diaphragm to the body. When using the GEMÜ Multiport SUMONDO, the actuator unit (multi-use) remains permanently installed in the plant, while the M-block (single-use) is replaced after use.
The compact M-blocks, which do not require tubes or piping between two seats, have a low hold-up volume in comparison with single valve solutions. This leads to greater process reliability and efficiency. Due to the compact design, less space is required in the plant. Production in accordance with GMP guidelines also ensures that the media wetted single-use M-blocks meet the highest standards in terms of purity, safety and stability.
Pneumatic or manual block locking
Two block locking options are available, which differ in the way the M-block (disposable) is connected to the actuator unit and offer either pneumatic locking (PSUA) or manual locking using a hand lever (PSUH). Both versions enable simple operation and fast replacement of the disposable between different production cycles.
The milled disposables can be manufactured in various designs, with different connections and sensor integrations for targeted use in the upstream and downstream area. This means that the M-blocks can be customised and implemented according to customer requirements.
