IDP-15 Dry Scroll Pump: Quiet, Clean & Reliable
The Agilent IDP-15 Dry Scroll Pump offers a peak pumping speed of 15.4 m3/h at 60Hz operation and 12.8 m3/h at 50Hz operation. The IDP-15’s hermetic design makes it well suited for use with helium applications and rare gas applications. The vacuum space in the pump is completely isolated from the motor and bearings, providing a clean gas path through the pump that eliminates any risk of oil or grease contamination. The IDP-15 uses a solid tip seal design that offers a long service life in most applications. The combination of the isolated design and the solid tip seal allow the IDP-15 to be better suited for applications which involve small amounts of condensable vapors such as water vapor. The single-sided scroll mechanism offers a quick and easy tip seal change as its basic maintenance. The IDP-15 is designed for extremely quiet (50 dBA) and low vibration operation that makes it ideal for use in laboratory settings and on analytical instruments such as mass spectrometers and electron microscopes. The AC single-phase motor accepts worldwide input voltages with a simple switch to set to either the high or low input voltage setting. An optional integrated inlet isolation valve closes the inlet of the pump immediately if power is interrupted to the pump for any reason.

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.
Zebra RH 0006-0030 A Two-Stage Rotary Vane Vacuum Pumps

With the new Zebra series Busch now also offers two-stage rotary vane vacuum pumps for applications in the medium vacuum range. For over 50 years, oil-lubricated rotary vane technology has been continuously developed and improved by Busch, with a constant focus on both economy and reliability in operation. High pumping speed efficiency and energy-efficient operation are the positive results of this development. Zebra rotary vane vacuum pumps are distinguished by a high pumping speed in the low-pressure ranges resulting in quick pump-down times. Model specific vanes are designed to guarantee long uptimes and the built-in oil shield ensures excellent oil separation for clean exhaust air. Built using the proven, robust, single-stage design technology, the Zebra two-stage rotary vane vacuum pump has a technically simple construction for generating improved end pressure. The consistent, high vacuum level achieved in continuous operation is guaranteed by forced oil lubrication, correct selection of component materials and precise, state-of-the-art manufacturing techniques. The built-in oil shield ensures clean and oil-free exhaust air. The integrated gas ballast valve, allows for large amounts of vapor to be processed, while maintaining an excellent vacuum level. An oil driven non-return valve mounted in the inlet flange opens when the pump is operating and prevents air from flowing back into the vacuum chamber by closing when the vacuum pump is switched off.

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.

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.
