Systemisation
CXS chemical dry pumps are available as stand-alone pumps or complete systems, including mechanical boosters for higher pumping capacities, and can be enhanced with a range of standard accessories such as valves, flame arresters, condensers, knock-out pots and filters.
Two models are available initially, the CXS160 and CXS250, which give nominal capacities of 160 m3h-1 and 250 m3h-1 respectively.
