Large Capacity Vacuum pumps

The AMV series is the result of the continuous improvement
of the single stage, air-cooled, oil sealed rotary vane vacuum pump.
These multi-vane pumps can achieve an ultimate vacuum of
up to 5 x 10-1 mbar (abs).
A special feature of this design is the rotor blades, which are made of a cast aluminium alloy.
The nominal vacuum capacities are from 100 to 1100 m3/hr at 50 Hz, or 78 to 780 CFM at 60 Hz.

WELCH - DuoSeal VACUUM PUMPS

Bypass feature produces higher vacuum at lower RPM. Carries off the last portion of gas and confines excess oil and volatiles to the exhaust side of each stage, leaving less contamination on the other side. Low speed operation reduces the rate of friction and wear on parts so pumps require less maintenance. Gas ballast valves for condensation prevention and removal of contaminates. Large oil capacity absorbs greater amounts of contamination. Single-stage pump 1399B-01 is recommended for continuous duty. All are mounted on a rugged steel frame and include V-belts, pulleys, belt guard, oil supply and instructions. Wired for 115V/230V, 60 Hz, Single Phase. Cord with North American plug and in-line switch provided with motors of 1 H.P. and below. Motors over 1 H.P. require conduit wiring.

Vacuum Equipment

Oil-sealed Rotary Pump -
Capacities are available from 1/2 to 1,000 cubic feet per minute, operating from atmospheric pressure down to as low as 2 x 10-2 torr for single-stage pumps and less than 5 x 10-3 torr for two-stage pumps. The pumps develop their full speed in the range from atmosphere to about one torr. The speed then decreases to zero at their ultimate pressures. Two of the most common designs are useful for pumping both liquids and gases. One is a two-bladed pump in which the rotor is eccentric to the stator, forming a crescent-shaped volume swept by the blades through the outlet valve. The second, a rotary piston pump, similar to a single blade, is part of the sleeve fitting around the rotor. The blade is hollow and acts as an inlet valve, closing off the pump from the system when the rotor is at top center.
Ultimate pressures attainable are limited by leakage between the high and low-pressure sides of the pump (due mainly to carry over of gases and vapors dissolved in the sealing oil that flash off when exposed to the low inlet pressure) and decomposition of the oil exposed to high temperature spots generated by friction.
Gas ballasting helps to prolong pump life because it removes the chief source of pump contamination, condensable vapors. The gas ballast is a vented exhaust that admits a small amount of air at atmospheric pressure to the compression side of the pump, thus permitting most condensable vapors to pass through the pump without condensing.
Typical applications of this pump are in food packaging, high-speed centrifuges, and ultraviolet spectrometers. It is also widely used as a forepump or a roughing pump, or both, for most of the other pumps described.

Mechanical Booster -
Capacities are available from 100 to 70,000 cubic feet per minute, operating usually in the pressure range from 10 to 10-3torr. The peak speed of the pump is developed in the pressure range from 1 to 10-2 torr. The speed at the lower end of the pressure range depends on the type of forepump used. A typical mechanical booster uses two figure-eight-shaped impellers, synchronized by external gears, rotating in opposite directions inside the stator. The gas is trapped from between the impellers and the stator wall and transferred from the high vacuum to the fore vacuum side of the pump. The gears are oil-lubricated but are external to the pump, so that the impellers run dry. Clearance between the impellers and the stator wall is generally about .002 to .010-inch. As a consequence, back leaking of gas occurs at a rate governed by the pressure difference between input and output and the type of gas being pumped. Under normal running conditions, a pressure difference of about ten to one is obtained. The mechanical booster must be backed by another pump in series when working in its normal pressure range. The most frequently used type of forepump is the oil-sealed rotary pump. Typically, the mechanical booster is employed for pumping vacuum-melting furnaces, in an impregnation plant for electrical equipment, and in low density wind tunnels.

Molecular Pump -
Capacities are available up to 20,000 cubic feet per minute, with an operating range of 10-1 to 10-10 torr, when backed by an oil-sealed rotary pump. The full speed of the pump is developed in the very wide pressure range from 10-2 to 10-9 torr. In the molecular pump, a high rotational speed rotor (up to 32,000 revolutions per minute) imparts momentum to the gas molecules, moving them along the small clearance between the rotor and stator. The molecular drag pump also employs this principle of operation. For ultimate base pressures it has been almost entirely displaced by the faster and simpler turbo molecular pump, in which radial slots in both rotor and stator fins actuate the pump. A number of compression stages are employed but because of its design, larger clearances can be tolerated between rotor and stator than were possible in the molecular drag pump. The molecular drag pump is sometimes built integral with a turbo molecular pump to allow the use of vert clean "dry" backing pumps. These hybrids are often used in semiconductor processing where oil vapor backstreaming would contaminate processes but high pumping speeds are needed.

Vapor Diffusion Pump -
This pump is mainly used on equipment for the study of clean surfaces and in radio frequency sputtering. Pumping speeds are available up to 190,000 cubic feet per minute with an operating pressure range of 10-2 to less than 10-9 torr when water-cooled baffles are used and less than 10-11 torr when refrigerated baffles are employed. The pumping speed for a vapor pump remains constant from about 10-3 torr to well below the ultimate pressure limitations of the pump fluid. The best fluids allow pressures of better than 10-9 torr. The diffusion pump is initially evacuated by an oil-sealed rotary pump to a pressure of about 0.1 torr or less. When the pump fluid in the boiler is heated, it generates a boiler pressure of a few torr within the jet assembly. High-velocity vapor streams emerge from the jet assembly, impinge and condense on the water or air-cooled pump walls, and return to the boiler. In normal operation part of any gas arriving at the inlet jet is entrained, compressed, and transferred to the next stage. This process is repeated until the gas is removed by the mechanical forepump.
The oil-vapor booster pump works on the same principles as the diffusion pump, but it employs a higher boiler pressure. Normal operating pressure range is 1 to 10-4 torr. When backed by an oil-sealed rotary pump, this pump is widely used for achieving high vacuum in thin-film evaporation units, accelerators, and in TV tube pumping.

Sputter Ion Pump -
Capacities are available up to 14,000 cubic feet per minute, with an operating pressure range of 10-11 torr. The full speed of the pump is developed in the pressure range from about 10-6 to 10-8 torr, although the characteristic at the lower pressure is dependent on the pump design. This pump uses a cathode material such as titanium vaporized or sputtered by bombardment with high velocity ions. The active gasses are pumped by chemical combination with the sputtered titanium, the inert gasses by ionization and burial in the cathode, and the light gasses by diffusion into the cathode.
A typical pump consists of two flat rectangular cathodes with a stainless steel anode between them made up of many open-ended boxes. This assembly, mounted inside a narrow box attached to the vacuum system, is surrounded by a permanent magnet. The anode is operated at a potential of about seven kilovolts (kV), whereas the cathodes are at ground potential.
The sputter ion pump has low speeds and sometimes instability when pumping inert gases. To improve its characteristics other types of sputter ion pumps have been developed: the slotted cathode, triode, differential, and magnetron pumps.
To start up a sputter ion pump it is necessary to reduce the pressure to at least 2 x 10-2 torr, and preferably much lower, by means of a roughing pump. Sputter ion pumps can operate in any position and do not need water or liquid nitrogen supplies. They have a long life and can provide very clean, ultrahigh vacuum, free of organic contamination and vibration. They are employed mainly for the clean-surface studies and in those applications where any organic contamination will give unsatisfactory results.
