These Vacuubrand MD 4C NT dry CHEMICAL diaphragm pumps have an ultimate pressure of 1.1 Torr, a pumping speed of 2.2 CFM. They include hose barb inlet and outlet connections of 8-10 mm and have an exhaust silencer. They operate on 1-Phase 110 to 120 VAC, and have Vacuubrand part number 20736403. These three-stage chemistry-design diaphragm pumps are an excellent solution for continuous, oil-free pumping of corrosive gases and vapors and meet even challenging requirements. The three-stage design provides the advantageous combination of high pumping speed and very low ultimate vacuum. All parts of the MD 4C NT in contact with pumped media are made of chemically resistant fluoroplastics. Well-proven PTFE sandwich diaphragms provide increased reliability and extended operating life. Due to the gas ballast valve and its very good ultimate vacuum (even with gas ballast) the MD 4C NT is also suitable for pumping condensable vapors of high-boiling solvents. The NT-series features further improved performance data, easy service and superior vapor tolerance.

Easy to use and maintain. They are lightweight, portable and enable you to move them to wherever and whenever you need vacuum. Connect the pump to your system with a vacuum hose and setup is complete. This is a new pump and set up for 115 Vac 60 Hz.
