Oilfree Generation of Vacuum With Diaphragm Pumps

Application

Diaphragm pumps are oilfree, dry and frictionless running pumps for the generation of vacuum as well as the delivery and evacuation of gases and vapours. In chemical laboratories they are the more powerful and modern alternative to water jet pumps, as they do not release any polluted waste water (environmentally friendly) at much lower operation costs (no water consumption). Typical applications: on vacuum drying chambers, distillation, drying and vacuum filtering but also as backing pump for turbo-molecular pumps, gas transfer and the like.

Advantages

There are one-, two-, three- and four-stage pumps available. The one-stage pumps are designed for an ultimate vacuum of approx. 80 mbar, the two-stage pumps for an ultimate vacuum of 9 mbar, the three-stage pumps for 2 mbar and the four-stage for down to 0.6 mbar. International Protection codes IP 54 or IP 20. They are quiet in operation and compactly designed. The pumps work almost maintenance free. Valves and diaphragms can be replaced easily on all models.

Two Versions

VACUUBRAND offers two different versions:

Aluminium version: Made of aluminium, FPM and PE. They are equipped with a hose nozzle or small flange on the inlet side and with a silencer on the outlet side.

Chemistry version "C": In these models pumped gases only come into contact with optimized chemically resistant fluoroplastics, e.g. with a PTFE-sandwich-diaphragm, ETFE clamping disc with stability core, PTFE/ETFE cylinder head, perfluorelastomer valves and PTFE/EFTE connections. On the inlet side with small flange or hose nozzle and on the outlet side with hose nozzles.
