Agilent Part No. 9499432M001 (REPLACEMENT DIAPHRAGM PUMP for Agilent TPS FLEXY Systems) The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases.

Vacuubrand Part No. 734003. These Vacuubrand ME-8 NT dry diaphragm pumps have an ultimate pressure of 52 Torr, a pumping speed of 4.8 CFM, a 3/8 inlet hose barb connection, have an exhaust silencer, operate on 1-Phase 110 to 120 VAC, and have Vacuubrand part number 734003. The Vacuubrand ME 8 NT pump is an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, and allow a wide range of applications for non-corrosive gases. The highly flexible, fabric-reinforced double diaphragm made of FPM is ideal for extended operating life. These pumps with four heads provide very high pumping speed. And this new NT-series features improved performance data.

These Vacuubrand MD-4 NT dry diaphragm pumps have an ultimate pressure of 0.75 Torr, a pumping speed of 2.5 CFM, a KF-16 inlet connection, include a 3/8 inlet hose barb, have an exhaust silencer, operate on 1-Phase 110 to 120 VAC, and have Vacuubrand part number 736005. The Vacuubrand MD 4 NT pump is an excellent solution for continuous, oil-free evacuation and pumping of gases. All parts in contact with pumped media are made of aluminum and selected plastics, and allow a wide range of applications for non-corrosive gases. The highly flexible, fabric-reinforced double diaphragm made of FPM is ideal for extended operating life. These pumps with four heads provide very high pumping speed. And this new NT-series features improved performance data.

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.
