Duplex strainer

Duplex strainers allows to operate installations without need to make stops in the process for cleaning and maintenance of the strainer, because they allow to operate one strainer meanwhile the other is under maintenance, working in alternative way. We offer different configurations with different types of valves for operation, be able to adapt to most applications.
  • DS1 Double-body basket strainer designed for solid particles retention in liquids, with alternative operation system to keep working non-stop when doing the maintenance and screen cleaning. 3-piece body with ball-valve main changeover system, operated with central lever. Same side connection and by pass for balancing. Removable covers to facilitate the screen cleaning.
