Klargester NSBE025 Bypass Separator - with FREE delivery!


Bypass separators are used when it is considered an acceptable risk not to provide full treatment, for very high flows, and are used, for example, where the risk of a large spillage and heavy rainfall occurring at the same time is small, e.g.



  • Surface car parks

  • Roadways

  • Lightly contaminated commercial areas


Features and Benefits



  • Light and easy to install

  • Inclusive of silt storage volume

  • Fitted inlet/outlet connectors

  • Vent points within necks

  • Oil alarm system available as recommended extra (required by EN 858-1 and PPG3) - please select this option if you require an alarm ready to wire in with your separator

  • Extension access shafts for deep inverts

  • Maintenance from ground level

  • GRP or rotomoulded construction (rotomoulded for NSBP003, NSBP004 and NSBP006)


To specify a nominal size bypass separator, the following information is needed:



  1. The calculated flow rate for the drainage area served. Our designs are based on the assumption that any interconnecting pipework fitted elsewhere on site does not impede flow into or out of the separator and that the flow is not pumped.

  2. The drain invert inlet depth.

  3. Pipework type, size and orientation.
