Benefits
KWT®Medium pressure penstock type: KSA-MD 100 t/m 800
The KSA-MD is a tried and tested penstock type, as it has been a long-standing product supplied by KWT. Next to the proven heavy duty penstock (KSA-HD) and the fully stainless steel medium duty KSA-MD-RVS, 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 between 6 and 8 MwC of water pressure from both sides, depending on opening size.
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.
