Protection against various aggressive vapors, which may attack the pump or pump oil Prevent high molecular weight vapors (such as might arise in a resin treatment plant), from reaching the pump. These vapors could cause lacquering or clogging The standard sorbent (activated charcoal), has relatively high trapping properties (absorbs around 25% of its own weight), even when large amounts of water vapor are being pumped. When filled with activated alumina on two-stage pumps, backstreaming of pump oil can be controlled
These catchpots minimize the entry of condensable vapors into the pump. Sorbent charge not supplied. Supplied with NW25 clamp, centering ring and ‘O’ ring.
