VACUUBRAND, Inc. Chemical Resistant Diaphragm Pump - Low Leakage - 1.5 mbar MD 4CRL NT

For applications requiring an especially high leak tightness of the pump, we recommend the MD 4CRL NT. The three-stage construction provides the advantageous combination of high pumping speed and very low ultimate vacuum of 2 mbar. All major parts of the MD 4CRL NT in contact with pumped media are made of chemical-resistant fluoroplastics or a special, highly corrosion-resistant stainless steel. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. Every single pump is tested for an integral leakage rate of 0.001 mbar l/s. Performance features outstanding chemical resistance exceptionally high performance even close to the very low ultimate vacuum integral leakage rate 0.001 mbar l/s verified at every single pump whisper quiet and very low vibration long diaphragm life, maintenance-free drive system
