Properties
Application
The diaphragm sample gas pump N012ST.11E is used for continuous extractive “hot gas” analytics. It mainly serves for unadulterated sucking and pumping of highly aggressive and corrosive sample gas above the dew point from sample point to the analyzer house resp. analyzer. Typical applications are emission measurements e.g. in waste incinerations and process measurements e.g. in chemical, petro-chemical, steel-, glass- or cement-industry.
Technology
The N012ST.11E is a reliable diaphragm pump with compact dimensions that guarantees an optimum integration in systems. It has a highly gas tight stainless steel pump head whose components have been developed especially for pumping of aggressive and corrosive gases. Special valves made of PTFE ensure a high tolerance to vapor and condensate as well as the PTFE-coated diaphragm. The results are an extremely long lifetime of the diaphragm and a high pneumatic performance of the pump. The pump is operating absolutely oil-free and ensures therefore an unadulterated pumping, evacuating and compressing of gases. The pump is ready for mounting and can operate in any position.
Functions
Core of the N012ST.11E is the elastic diaphragm which is moved up and down in its center by an eccentric. In this way gas is pumped through self-opening and-closing valves. Due to the IP54 housing of the motor it is protected perfectly against spray water, dust and dirt. The desired temperature can be adjusted at the electronic controller with display. External control of the pump via PC is possible with special software and RS232 interface.
