Vacuum pump - Wikipedia

Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off the cavity, and exhaust it to the atmosphere. Momentum transfer pumps, also called molecular pumps, use high speed jets of dense fluid or high speed rotating blades to knock gas molecules out of

To generalize their applications, transfer pumps are used for high gas loads while capture pumps produce oil-free vacuums and UHV pressures. Applications. 1. of the pump. The pumping speed curve shown (a) illustrates the characteristic differences between roots pumps, mechanical pumps, and high vacuum pumps.

rotary pump for reaching rough vacuum, and the diffusion pump for reaching high vac- uum. These will be discussed first followed by other pumps. For each pump we need to discuss several things: 1. How it operates. 2. What pressure range it operates in. 3. Its pumping speed. 4. Type of gas flow (viscous or molecular). 5.

Pfeiffer Vacuum turbopumps with their optimized reliability use proven bearing systems which are available in two different options - a hybrid 

Pfeiffer's High Speed ( 226L/min) Oilless Dry Vacuum Pump, 10E-2

Low maintenance cost: ACP pumps require overhaul only 20,000 hours of operation for the ACP 15 resulting in low cost of ownership. Condensable vaporability: High flow gas ballast ports and drainable silencers allow the ACP to pump high amounts of condensable vapors (up to 1,000 g/h of pure water vapor). Cold trap 

High Performance Scroll Pump Technology - Edwards Vacuum

nXDS Scroll Pumps. With exceptional pumping capability, ultimate vacuum performance and state-of-the-art design features Edwards nXDS is the best performing pump in its class. nXDS improves on legacy XDS pumps by offering increased pumping speeds, combined with lower ultimate pressures, lower power 

High Vacuum Pumps Information | Engineering360 - GlobalSpec

They are among the most widely used high vacuum pumps. Diffusion pumps are very reliable, have no moving parts, and have long service lives. They provide the highest pumping speed for lighter gases like helium and hydrogen. Process contamination and backstreaming of oil in oil diffusion pumps can be a problem, but 

Diaphragm Pumps - Pfeiffer Vacuum

Beginning with a pumping speed of 0.25 m3 per hour, you can choose from a wide selection of pumps. Absolutely dry, oil-free vacuum; Long lifespan of the diaphragm; Low vibration and sound; High operating safety; Maintenance-friendly through easy diaphragm and valve exchange; Worldwide usage through dual 

Venturi Vacuum Pumps for High-Speed Pick and Place Systems

ANVER VR Series Venturi Vacuum Pumps feature aluminum construction with brass inserts, have no moving parts to wear out, and can pull a 26” Hg vacuum with only 0.74 to 1.27 SCFM air flow and 72 psi supply pressure. Ideally suited for high speed pick and place systems where they can be positioned close to the parts
