Alcatel Turbo Pumps: MDP Molecular Drag Pumps Description This best-selling vacuum pump is an ideal alternative between turbo and Roots pumps. They are designed on the basis of the Holweck principle. This high technology pump includes 3 different stages : (1) a preliminary stage with a row of blades for the maximum conductance to ensure the highest possible pumping speed. (2) a stage with a drum with a multi-ribbed structure to ensure the maximum efficiency and a high compression ratio. (3) a stage with a dynamic seal which allows the pump to operate with a high exhaust pressure.

Features Simple construction Light and compact Robust rotor Low rotational speed High exhaust pressure tolerance Benefits High throughput Can be mounted in any position High compression ratio High pumping speed at high inlet pressures Cost effective Applications Fast evacuation of small volumes Fast cycling of volume Interseal pumping Alternative for rotary vane pumps at 103 to 104 mbar Regeneration of cryopumps Backing pump for turbomolecular pumps Leak detection High-quality freeze drying Spectrometry Production of light bulbs Prodcution of electronic tubes Specifations and Ranges Offers high pumping performance between 10 mbar and 105 and a maximum flow rate of 600 sccm. High exhause pressure up to 40 mbar Ultimate pressure up to 107 mbar
