Displacement Pump for Aggressive Gases with Condensate
Application area
Gas analysis and gas measuring technology, process technology and engineering, air conditioning and ventilation technology, environmental and hygiene technology, biotechnology
Product specification
Highly robust sample gas pump for delivery of aggressive gases and gas mixtures according to the displacement principle. The pump is fitted with a bellows and therefore excellently suitable also for delivery of gases with entrained liquid.
Due to its special bellows construction, the pump features a far longer service life compared to diaphragm pumps especially when delivering gases with entrained liquid.
The bellows is made of one solid piece and consists of PTFE.
Very robust design.
Manufactured with high precision, thus minimum noise emission and high quietness of running.
Valves made of PTFE (polytetrafluoroethylene) and PEEK (polyether-etherketone) for highest resistance to chemically aggressive media as well as high thermal loading capacity.
Pump head made of PTFE with highest resistance to chemically aggressive media. PTFE is flexible compared with stainless steel, thus this design is advisable for the delivery of gases in tubed analytical systems.
Pump head made of stainless steel 1.4571 allows highest gas tightness and outstanding mechanical robustness. The pump is suitable for delivery of gases in piped analytical systems.
Optionally with bypass valve in the pump head for rough regulation of the delivery rate to specified values <100 %.
Support console with vibration dampers for easy installation.
Easy to replace valves.
The plastics PTFE and PEEK are highly resistant to countless aggressive media and reagents. Below are given the flue gases important in heating engineering and fuel technology as well as the acids usually resulting as aggressive condensates from the reaction of flue gases with water.
