GV Oil-Sealed Vacuum Pumps

 

Atlas Copco’s expertise in air compressors is now applied to vacuum pump technology. Atlas Copco now designs and manufactures its own vacuum pump systems with the same quality and reliability as those of Atlas Copco’s compressors. With the new GV oil-sealed rotary screw vacuum pump, is a pump system for rough vacuum between 0.5mbar and 500mbar. The GV offers a reliable, efficient vacuum. At the heart of the new GV is an in-house designed, reliable screw element. In this operating pressure range, oil-sealed rotary screw technology offers the best performance at the lowest energy cost. Wih its modu- lating valve fitted at the pump inlet, the capacity can be matched to the actual demand. This concept not only minimizes the sys- tem’s vacuum level fluctuations, but also operates the pump at the lowest possible energy point. The vacuum pump also has to stop/start less frequently, leading to less wear and maintenance and therefore increased reliability. The GV delivers capacities between 500 and 5000m3/h, making it suitable for many ap- plications. From printing and packaging to plastics, electronics, woodworking, bottling and canning, the GV delivers consistent and efficient vacuum. With its quiet operation, the GV can be installed close to the point of use but this technology also allows for remote installation as part of a centralized vacuum system.

Rangu DF 1000-2800 A Diffusion Vacuum Pumps

 

Rangu is the new range of diffusion vacuum pumps from Busch. Busch Rangu diffusion vacuum pumps are designed to withstand heavy industrial use and can handle high gas loads. The Rangu range has an innovative multi-stage jet design providing stable vacuum performance even under difficult flow conditions. It also provides industry-leading performance in reducing the potential for oil back streaming to prevent process contamination. Busch offers a comprehensive range of diffusion vacuum pumps and systems for industrial uses. The Rangu diffusion vacuum pump construction consists of an oil boiler connected to a central multi-stage jet assembly. The heated oil is ejected from the jet assembly at supersonic speeds and the process gas molecules are entrained in the oil jet flow and transferred through the pump body by the heavier oil molecules’ momentum. This process moves the gas molecules from the low-pressure inlet flange to the foreline vacuum port of the diffusion pump, where the oil is condensed and returned to the boiler. The backing pump then removes the process gas molecules. The Rangu diffusion vacuum pump’s innovative multi-stage jet design results in the utmost stability of the pumping operation. The design is especially suited for high transient pressures typically found when pumping down a chamber without the associated risk of oil back streaming. All Rangu diffusion vacuum pumps benefit from a robust long life heater design, which ensures stable and reliable performance under widely varying operating conditions.

Turbo-60G Oil-Free Pump Package

 

The DRIVAC Inc. Turbo 60G is a compact, air-cooled, portable turbopump package. This fully integrated 35lb. package includes a 60 L/sec. hybrid turbomolecular pump, an oil-free backing pump, automatic valving, and a control module. Operation is automatic and interlocked, and the TURBO 60E is not adversely affected by operator error or power failure. Vacuum in the user’s system remains undisturbed in power failure situations. The footprint is 8” × 11”. Modular construction permits direct mounting of the turbopump to the system flange, and remote mounting of the control module. The rugged, industrial-grade oil-free backing pump has a mean-time-between-failure rating of 25,000 hours for the rotating mechanisms. A wide selection of standard inlet flanges is available. The hybrid turbopump can be directly mounted onto the user’s system flange. This results in substantially increasing the net high vacuum pumping speed at the system inlet. The exhaust pressure of the hybrid pump is in the viscous flow range. This permits remote mounting of the backing pump without increasing pumpdown time. The oil-free backing pump used in all Hovac packages eliminates the requirement of venting the turbopump in power-fail situations. When the power goes off, the normally-closed solenoid valve isolates the turbopump from the backing pump. When power resumes, a time-delay relay keeps this valve closed until vacuum is re-established in the foreline. The Vacuum Monitor sensor and circuit incorporated into the TURBO 60 package automatically controls operation of the hybrid turbopump. This prevents extended operation of the turbopump at high pressures. This helps to maintain a lower operating temperature of the turbopump thereby enhancing long-term reliability.

Dual Sorption Roughing Pump Assembly

 

MDC’s sorption roughing pumps, or sorption pumps, are used for pumping systems from atmospheric pressure to a pressure of approximately 10-2 Torr. They rely on the dispersion forces existing between a gas and a surface to bind gas molecules on chilled surfaces inside the pump, i.e., they pump by cryosorption. Sorption pumps typically consist of a cylindrical canister or body that is filled with an adsorbent material. The pump body and internal cooling fins are specially designed for maximum heat transfer. The pump neck and flange are made of stainless steel. The pumps are mounted and supported by the flanges and since stainless steel is a poor thermal conductor frosting of adjacent components is minimized. Sorption pumps need liquid nitrogen to operate and, as with any capture pump, they have to be periodically regenerated. Sorption pumps are very clean non-contaminating roughing pumps and are ideal for low throughput applications. They are used in conjunction with getter pumps, ion pumps, or mechanical cryopumps. It has a 1×10-3 Torr vacuum level, is an economical roughing source with no moving parts. It has vibration free operation with heat regeneration and a positive pressure safety vent. Multiple pump capability is available and it has a clean and non-contaminating operation.

Oilfree hybrid bearings with lifetime lubrication are extremely reliable and durable making regular maintenance by way of oil changes superfluous. The bearing system ensures low vibration and low noise operation – thereby being less demanding with respect to applications that are sensitive to vibrations. The ceramics ball bearings are replaceable on-site should this be required. The innovative thermal design of the TURBOVAC i ensures optimum cooling of the bearings. To protect the bearings against critical gases or particles, all pumps have been equipped with a purge gas connection. In order to keep installation, operation and maintenance as simple as possible, the TURBOVAC i is equipped with a rotatable vacuum flange connection, integrated drive electronics with direct 24/48 V DC supply as well as a flexible communication interface with USB, RS 485 and digital I/O ports. Additional interface options are available upon request.

Model 800-28 and 200-7 Soft Start and Pressure Control for Rotary Vane Pumps

 

To minimize turbulence and particles during evacuation, you may “Soft Start” your pump down and then switch to maximum speed to give the ultimate vacuum you need. When your system pressure reaches the required vacuum, you may want to slow the pump again to perhaps 20% of capacity. For pressure control, just determine the vacuum level that is best for your process and adjust the set point on your vacuum gauge accordingly. The Vacuum Research Corporation pump will then run at maximum speed until that pressure is reached and will then slow its speed to maintain the vacuum you have selected. Adjust the dead band, or hysteresis, on your gauge to give the control range that you need. For roughing with either cryo or ion pumps, you can operate your mechanical pump at maximum speed, or use a Soft Start Program. When the high vacuum pump takes over, slow the mechanical pump to about 20% of capacity and keep it running slowly so it will be warmed up and ready for the next pump down cycle. Or if the high vacuum cycle is very long you may want to turn the mechanical pump off when roughing is complete. Backing of Turbo and Diffusion Pumps Use a single mechanical pump for roughing and backing for turbo or diffusion pumps. For roughing, ramp the pump speed up slowly to minimize turbulence in the chamber. After crossover slow the mechanical pump to perhaps 25% of capacity. If your foreline gauge has a process control relay an unexpected increase in pressure will switch the pump to full speed until the pressure recovers.
