Strong, Robust and Cost-Efficient
The all-new KNF N 922 series pumps for gas sampling are designed to be extremely easy to service. While modified PTFE, FFPM and other materials/coatings are used to offer long durability and great resistance to chemicals, these pumps take one step further by helping to reduce the operating costs—the only parts that have to be replaced are the diaphragm and the valves.
Depending on how the pump is used, the maintenance work just has to be performed once a year and can be easily carried out by using a standard tool.
Few replacement parts, long periods between required maintenance work, and low costs for spare parts make N 922 series pumps an excellently cost-efficient choice for gas sampling applications.
Higher Permissible Ambient Temperature
Moreover, compared to previous models, the more advanced N 922 series pumps can operate at higher ambient temperatures of up to 60°C.
