Leybold Dry Screw Pump Varodry VD 200, 230/460V 3ph. 60 Hz., with purge gas module P/N 111200V16 60 Hz, 230/460 V ±10%, 3 ph These VARODRY are fully air-cooled and oil free. That results in the fact that the VARODRY only consumes electricity. You will never experience any extra costs for cooling water supply or oil/oil filter exchange and disposal. Additionally, its low power consumption offers you significant energy savings. The Total Cost of Ownership savings offered by VARODRY are a market benchmark for a wide range of demanding applications, expecially where standard pumps require a lot of maintenance. And copared to oil sealed rotary vane pumps the VARODRY will save you money in operational costs. The VARODRY provides a competitive pumping speed over the complete pressure range and a low end-pressure of < 0.01 mbar. It can operate continuously at any inlet pressure. The effective pumping speed generated per consumed power is a market benchmark for industrial dry pumps. User Maintenance: With only two wearing parts (belt and bearings), only minimal efforts are required to keep your pump running at peak performance. At the same moment, the uptime of your facility will be strongly improved. The belt can easily be exchanged by you, in less than 30 minutes. The partly removable enclosure makes this really convenient. The belt exchange interval depends on the individual application, typically it is one year. Belt exchange kits and maintenance tools are available for you. Furthermore, we offer you solutions for multiple pump control via ECOntrol 6 V/16 V or ELEC CAB. Standardized combinations with RUVAC roots blowers are also available. Repeated and Fast Cycling: The VARODRY offers a very quick pump down. The pump tolerates atmospheric pressure shocks and repeated evacuation cycles. Dust / Particle Handling: The rotor screw principle and anodization offers the best performance to handle fine, dry dust particles. In the case of large dust amounts, a wide filter portfolio is available. Vapor Handling: Due to its optimized temperature profile and the built-in gas-ballast, the VARODRY offers a high vapor tolerance, avoiding internal condensation. Reactive Gas Handling: Often vapors (e.g. hydrocarbons) tend to react inside hot dry pumps and built-up internal coatings which can cause pump seizing. The internal temperature profile virtually eliminates this risk. Liquid Handling: The VARODRY can handle droplets or even liquid slugs as the liquids can flow freely out of the pump.

Leybold DryVac DV 300 Dry Compressing Screw-Type Vacuum Pump, 200-240V, Pumping Speed: 280 m^3/h (164.8 cfm), Ultimate Pressure: < 0.01 mbar (< 0.0075 Torr). Leybold Part Number: 112030V19. These Leybold DV 300 Dry compressing screw-type family were developed in view of the special requirements of industrial applications, s is engineered for the new era of smart manufacturing. Packed with intelligent features and functions, all DRYVAC models offer seamless connectivity, networked control and superior efficiency. DRYVAC pumps boost your productivity, minimize your carbon footprint, and lower your costs. Plus, thanks to an integrated smart service concept, they virtually look after themselves. The innovative, modular design of the screwline allows these pumps to be used in all cases where reliable, compact and low maintenance vacuum technology is demanded. Screwline pumps are suited for all applications with higher requirements regarding the backing pump, like for example in processes involving high particle counts or in the hard production area. The dry compressing Screwline pumps are an ideal alternative to conventional oil-sealed vacuum systems. Screw RotorsThe screw shaped rotors are fitted to two horizontally arranged shafts and revolve without making contact within the pump chamber. The shafts are synchronized by a toothed gear. The shafts are driven via a further gear stage by an electric motor. In vacuum pumps, the seals and the bearings on the vacuum side are always a potential source for a breakdown. On the one hand lubricants may enter from the bearing into the vacuum process and on the other hand aggressive process media can endanger the bearings. Cantilevered BearingThese disadvantages are avoided by the “cantilevered” arrangement of the rotors. The ScrewLine is equipped with two cantilevered screw type rotors which are guided by oversized shafts and bearings. The bearings are both located in the gear chamber of the pump. A further advantage of the cantilevered arrangement is that the pump chamber is easily accessible without having to disassemble any bearings. Thus any possibly required cleaning operations necessary due to the influence of the process can be run easily. The cantilevered rotors minimize the risk of bearing damage and also reduce on-site maintenance to a minimum. Shaft SealsShaft seals are in the case of the ScrewLine pump only required on the delivery side of the rotors. Owing to the small pressure difference between exhaust and gear, simple and reliable seals can be provided. The two shaft seals consist of a combination of a piston ring and a labyrinth seal thus making almost no contact so that the seals will be almost free of wear. CoolingThe ScrewLine is air-cooled. A radial fan supports the cooling effect for the casing which is equipped liberally with cooling fins. Depending on requirements, the ScrewLine pumps may be combined with Roots pumps so as to attain higher pumping speeds at lower pressures. PRINCIPLES OF OPERATIONIn the ScrewLine vacuum pumps the pump chamber is formed by two synchronized displacing rotors and the housing. A pair of tightly intermeshing right-handed and left-handed threads is used to implement with only very few components a large number of stages and thus very low ultimate pressures. Gas CompressionThe screw shaped rotors are fitted to two horizontally arranged shafts and revolve without making contact within the pump chamber. The shafts are synchronized by a toothed gear. The shafts are driven via a further gear stage by an electric motor. In vacuum pumps, the seals and the bearings on the vacuum side are always a potential source for a breakdown. On the one hand lubricants may enter from the bearing into the vacuum process and on the other hand aggressive process media can endanger the bearings. SLOTSAs in the case of other dry compressing (slot sealed) vacuum pumps, also in the case of screw pumps very tight slots need to be maintained between the components. Otherwise the leaks caused by the pressure drop would have a negative effect on both pumping speed and attainable ultimate pressure. Moreover, the pump might heat itself up too much due to unfavorable thermodynamic processes. During operation the design of the ScrewLine ensures that the slots are maintained within the operational limits of the pump. In order to limit the temperatures attained by the components, the housing of the pump chamber is air-cooled. Also the rotors themselves are cooled: by oil which is pumped through bores in the rotor shafts and which also lubricates the bearings and the toothed wheels of the pump’s synchronising gear. Thus an uniform temperature spread is attained within the pump. The amount of “inner compression” has a significant influence on the temperature level within a vacuum pump. In the case of a foreline pump, most of the work on compression is done while the gas is being ejected against the delivery pressure, i.e. in the last stages of the pump. For this reason in the case of the ScrewLine the volume of the gas is already significantly reduced at pressures which are as low as possible so as to minimize this work done on compression. In this way the power requirement of the pump is reduced and less heat needs to be dissipated.

Purge GasIn standard applications no purge gas will be required at the seals. However, if demanded by the process conditions, a purge gas unit from Leybold Vacuum (P/N 119 031) may be connected.

Leybold RuVac WSU-501 Roots Blower Booster Vacuum Pump, Hydrocarbon LVO-100, 3-phase, 208-230/460 VAC. PN 11733. The Leybold WSU 501 WSU-501 HYRDOCARBON OIL standard series Root’s blower vacuum pumps are driven by air cooled motors. They have no shaft feedthrough to the atmosphere, thus the Leybold WSU 501 WSU-501 is particularly leaktight. In the canned motor, rotor and stator pack are separated by a vacuum-tight can made of a nonmagnetic material. The rotor operates on the drive shaft of the pump in the vacuum, so that a shaft seal which would be subject to wear is not required. The WSU pumps are easy to operate! They include a pressure differential valve that allows them to be started at the same time as the roughing pump. In the event of an excessively high pressure difference between the flanges, the valve will open. Then a part of the pumped gas will flow through this line back to the intake flange. Therefore the pump may be switched on together with the backing pump at atmospheric pressure. This increases the pumping speed of the pump combination also at high intake pressures. These Leybold WSU 501 WSU-501 are chemical series pumps being prepare from the factory with HYDROCARBON LVO-100 standard vacuum pump oil. These blowers are stock items and typically can ship instantly from our warehouse and have Leybold part number 11733. The price for the pump listed is for a Leybold WSU 501 WSU-501 blower booster HYDROCARBON standard LVO-100 oil prepared vacuum pump only, backing pumps are extra. We also sell mechanical and blower vacuum pump systems. Please call (505) 872-0037 for more information.

Ideal Vacuum Small Super-Seal KF-40 Flanges Right Angle HV Pneumatic Bellows Valve, Auto Closing. These small Ideal Vacuum Super-Seal pneumatic bellows 90° angle valves have KF-40 inlet and outlet ports. They are designed primarily for use in the high-vacuum range (10-8 Torr), with leak rates of 10-9 Torr l/s (He) but can be used up to positive pressures of 60-80 psi. These valves are constructed of a 304L stainless steel valve body and mechanism, an aluminum actuator, and Viton bellows seat O-ring seals. Super-Seal valves are bakeable up to 100°C (valve body only). These valves can be mounted in any orientation. These small-sized Super-Seal valves require air to open and have a spring closure mechanism. Low volume, dry, compressed air in the range of 60-to-80 psi is needed. Because they close automatically, they are useful as safety valves, providing failure protection to preserve chamber vacuum in case of loss of power or air supply. Air flow to open the valve is controlled by a single-acting, electrically operated solenoid. A selection of four solenoid voltage choices is offered: 12 VDC, 24 VDC, 110 VAC, and 220 VAC. Three position indicator sensors are available for Super-Seal valves, including a mechanical reed switch and two transistor types (NPN and PNP). Each sensor has a LED which provides visual confirmation of the valve’s state (whether it is open or closed). These sensors can also be used to switch or trigger auxiliary devices. The Super-Seal family of valves includes weldable tube, KF, ISO-K, and Conflat (CF) flange options, from 3/4" OD tube (KF-16), to 10" OD tube (ISO-K 250), and many are available in right angle (90°) and inline versions. These valves are a great value and are extremely reliable, making them useful for applications such as semiconductor manufacturing, plasma physics research, and nuclear accelerators. They are a primary component in vacuum process automation and have a mean time to failure rate (MTTF) of more than one million cycles. Solenoids and position indicator sensors are sold separately.

Single Acting 24 VDC Solenoid Kit for Small Super-Seal Pneumatic Bellows Valves, KF10 to 50, CF1.33 to 3.38, Tube 0.75 to 2.0 in. This is a 24 VDC single-acting solenoid kit used on all small Ideal Vacuum Super-Seal pneumatic bellows valves, including 90 degree angle and in-line valves. The kit includes a 1/8" brass NPT nipple needed to attach the solenoid to the 1/8" female NPT air inlet of any small Super-Seal valve. Also included is a push-to-connect fitting with 1/8" NPT to 1/4" OD tubing for the airline connection, and a 1/8" NPT sintered brass exhaust muffler. This solenoid requires a 24 VDC power source capable of supplying a current of 200mA. This single-acting solenoid kit is used on these small Super-Seal pneumatic bellows valves: KF-16, KF 25, KF-40, and KF 50 CF 1.33", CF 2.12", CF 2.75", and CF 3.38" Weldable Tube 0.75", 1.0", 1.5", and 2.0" OD tube Small Super-Seal valves use air to open and have an internal spring closure mechanism. Low volume, dry, compressed air in the range of 60-to-80 psi is needed to operate the valve. When energized, the solenoid directs air flow into the valve through the solenoid’s manifold. When the solenoid is de-energized, air flow to the valve is cut off and the valve is closed automatically. Because small Super-Seal valves close automatically, they are useful as safety valves, providing failure protection to preserve chamber vacuum in case of loss of power or air supply.
