Vacuum Pump for Hazardous Gases and Contamination-Free Analytics

Vacuubrand offers especially tested leak tight diaphragm vacuum pumps for applications in which hazardous (toxic) gases are to be transferred or that require contamination free transfer of gases at defined purity stages. This includes transfer of particularly harmful or highly valuable gases, or process gases used for analytics of single gas components. Particular leak tightness means specified and tested leakage rate. Vacuubrand’s new chemistry diaphragm pump MD 4CRL NT is not only featuring an especially low leakage rate which is 100% tested at every  single pump, but has also been designed for use with corrosive gases. All mediacontacted parts are made of  fluorinated polymer materials and highly corrosion resistant stainless steel components (e.g. V4A). High pumping speed rates (3.4 m3/h at atmospheric pressure) over the full range down to close to the ultimate vacuum of 1.5 mbar  suits the needs of many vacuum applications and processes.

Furthermore the patented drive system assures extremely silent and low-vibration operation. All VACUUBRAND  chemistry diaphragm pumps feature the well proven PTFE sandwich-diaphragms as well as the stability-core design  of the media contacted cylinder head part and diaphragm clamping disc resulting in high chemical resistance and  outstanding diaphragm lifetime with low maintenance requirements. Each and every MD 4CRL NT is leak tested  (leakage rate specification limit 1 x 10-3 mbar l/s) to provide reliable leak tightness, even in long-term operation. It is usable for many applications in transferring highly valuable, corrosive, or even toxic gases, and is also usable as  sample gas pump.
