Medium pressure penstock type: KSA-MD

Application
KKWT penstocks are available in various forms and are used in surface, sewer and process water systems.

Operation

The KSA-MD is a tried and tested penstock type, as it has been a long-standing product supplied by KWT. The range has been recently extended to include a lighter-duty penstock (KSA-LD) and a heavier duty penstock (KSA-HD), however the KSA-MD continues to be a very popular product for the majority of applications. The penstock consists of a vertically sliding door that closes a round opening, moving within a stainless steel 316L frame with HDPE guides. The seal between the door and frame is achieved through an EPDM lip seal positioned in the moving plate that retains up to 5MwC of water pressure from both sides.The penstock is supplied with a non-rising spindle as standard, however on request the penstock can also be supplied with a rising spindle. Although the wall mounted type is the most popular, we can also supply these with pipe and flange connections.
