buesch.com CP4-RS semicircular penstock Size 150 to 600 mm, with planar passage The CP4-RS is first choice for semicircular applicatione, due to easy installation and first-class corrosion protection. The planar passage and the high quality sealing makes the CP4-RS the ideal solution for penstocks in standardised chambers. The pre-stressed sealing gives the CP4-RS an outstanding sealing perfomance in on-seating and off-seating conditions. The CP4-RS is available in nominal sizes from 150 to 600 mm and in three different versions: for installation in a pre- sent channel, for additionally mounting into shafts or embedding in a newly built channel. Sealing performance ▪ Maximum static and dynamic pressure in on-seating condition: 0,4 bar (4 m wc) ▪ Maximum static pressure in off-seating condition: 0,4 bar (4 m wc) ▪ Maximum 1 % of permissible leckage rate in accordance with DIN 19569-4 under on-seating conditions ▪ Maximum 5 % of permissible leckage rate in accordance with DIN 19569-4 under off-seating conditions ▪ Steady sealing performance irrespective of water level ▪ Wastewater resistant sealing material Installation advantages ▪ Compact design, one-unit-delivery, ready to install ▪ Quick and easy installation with a few dowels ▪ No additional adjustment necessary on the penstock ▪ Also available for embdding into channels Operation advantages ▪ Maintenance free ▪ Self-cleaning stem nut ▪ Durable operating reliability Corrosion resistance ▪ Maximum corrosion resistance due to stainless steel material, all acid cleaned and passivated in own pickling plant Operation ▪ Operating key, hand wheel, electric or pneumatic actuator, gears and a wide range of extensions: see BÜSCH MAS programme Customisations ▪ For dowelling in the bottom ▪ For embedding in concrete Accessories ▪ MAS Modular Actuating System packages: see BÜSCH MAS programme ▪ MOBITORQ Mobile Actuator: see brochure ▪ BEA BÜSCH Electric Actuator: see brochure ▪ Operating key: e.g. All-in-One operating key Areas of application ▪ Municipal and industrial wastewater treatment plants ▪ Applications in drains, chambers or channel systems Materials Frame: Stainless steel SS304 or SS316Ti Sliding plate: Stainless steel SS304 or SS316Ti Sealing: EPDM, wastewater resistant or NBR Stem: Stainless steel SS304 or SS316Ti Stem nut: GC-CuSn 12, seawater resistant bronze Chem. anchor bolts: Stainless steel S32304 Other materials available on request. 2019-03-29|en Version: embedding of planar passage
