Product specification

Highly robust sample gas pump for delivery of aggressive gases and gas mixtures. The pump is fitted with a PTFE bellows made of one solid piece and operates according to the displacement principle.

Very robust design.

Manufactured with high precision, thus minimum noise emission and high quietness of running.

Valves made of PTFE (polytetrafluoroethylene) and PCTFE (polychlorotrifluoroethylene) 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 PCTFE are highly resistant to countless aggressive media and reagents. A resistance table is available on request.
