Water vapor pressure at this temperature is at 18 Torr so pressures below this marking will allow the greatest amounts of water to be evolved. The combinations of water vapor and gas will enter the vacuum pump near the inlet side and will then be sent into the high-pressure side through the pumping action.

In the end, a gas ballast valve is a very simple device that can be utilized to drive off condensables when operated properly. The Pfeiffer ACP series of dry lobe (or multi-stage roots) pumps offer many distinct advantages over other displacement pumps including: Dry multi-stage Roots technology, SD versions, ACP pumps with a pumping speed of max. 15, 28, and 40 m 3 /h; No particle contamination, thanks to frictionless design: no wearing parts in the pumped gases pat Page 18 Operation Fig. 11: Standard version 42 of gas ballast valve Gas ballast valve with If the pumping process requires the use of flushing gas, a supply hose can be connected at the gas ballast valve. flushing gas connec- tion (option) Fig OPERATING INSTRUCTIONS EN Translation of the original instructions DUO 125, DUO 125 M Safety instructions The safety instructions in Pfeiffer Vacuum operating instructions are the result of risk - Sight glass and gas ballast valve must be visible and readily accessible

These have dual voltage: 115-230V motors and have a manual gas ballast Gas ballast prevents condensation of vapors inside the pump by diluting the pumped gas with the air being drawn in through the ballast valve. Once the air is drawn in and mixes with the pumped gas, the water vapor being carried in the pumped gas makes up a smaller percentage of the gas, which now includes the ballast gas (air) as well The integrated two-stage gas ballast and safety valve ensure process-specific and safe operation.

This is usually measured in grams (or ounces) of water per hour. If there is a chance that the pump will be experiencing higher levels of water than the specified limitations, a condenser might be a good solution. Moreover, the effects of the gas ballast on the ultimate pressure are lower, as the ballast gas is only admitted in the second stage Pump oil, which is also called as operating fluid, has multiple.

We support all major manufacturers including Pfeiffer Vacuum, Alcatel / Adixen, Edwards Vacuum, Varian, Oerlikon / Leybod Vacuum, Vacuubrand, and Agilent Technologies.Soon the volume of dry gases and vapors will be reduced by the mechanisms which are increasing pressure on the exhaust. This mixture is combined with the partial pressures of both gas and vapor constituents that make up the sum pressure of the entire chamber. Once the gas ballast has opened air will be introduced to the chamber and restore normal atmospheric pressures.

Rotation speed at 60 Hz 1800 min-1 When the gas ballast valve is opened it will prevent the vacuum pump from fully achieving the vacuum. Once the cycle has neared its end and a lower pressure is needed, the gas ballast can then be closed once all of the water has been pumped from the system.A proper non-return check valve is another important component of all gas ballast valves and is located between the exterior and the intake into the stator volume. It is important to the process that air enters the pump, but we don’t want vapor mixtures and exhaust gasses to leak out through the gas ballast valve. This is prevented by the non-return check valve closing the ballast line once the point in the process where pressure exceeds atmospheric pressure has been reached and exhaust valves opened.

4.1.6 Gas ballast. Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast. If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with the ballast gas Pfeiffer ACP 28 Compact Multi-stage Roots Type Booster Blower Vacuum Pump Rebuilt, Refurbished.

Properly using a gas ballast valve as found on a mechanical oil sealed vacuum pump has been considered by some to be an arcane art and practiced blindly much of the time. Actually, gas ballasting is a very simple operation and when properly applied can keep vacuum pumps in optimal conditions even when used in wet processes that can potentially contaminate the oil with condensation. Abstract: A gas ballast system for a multi-stage positive displacement pump in which a first stage includes at least one positive displacement pump stage, is equipped with an inlet valve and an outlet valve, and is connected with the following stage by an intermediate vacuum chamber, with the gas ballast system including a first conduit for.

Scroll pumps are an excellent alternative to rotary vane pumps where oil free pumping is desirable. The XDS pumps in particular use an innovative bearing shield to isolate the vacuum environment from all forms of lubricant not only making them totally dry, but also protecting the bearing from any process gases. Vapour handling is enabled by an adjustable gas ballast; this allows the range of. Pfeiffer Vacuum scroll pumps from the HiScroll range. Excellent water vapor tolerance thanks to the two stage gas ballast. As a result condensation in the vacuum pump is avoided. With these features, the pumps are ideal for use in many applications in analytics, biomedicine, pharmaceuticals and research and development..

To avoid the added work of hand-operating the gas ballast valve, this task can be handled by a solenoid operated valve that can be connected to the main process control system and controlled automatically. This is convenient because there are stages during the process where this valve should be opened and other times when it should remain closed. There are also some processes that involve hazardous gases. Because both oxygen (O2) and water (H2O) are constituents of the air around us, they can react with some chemicals in a process, for this reason, nitrogen can be used because of its inert qualities. - Single-stage, high-performance rotary vane pump with a pumping speed of 4.8 m³/h at 50 Hz / 5.8 m³/h at 60 Hz - With single-phase motor with C14 connector plug inside the terminal box - Integrated gas ballast and safety valve - For all low and medium vacuum applications - Optional with magnetic coupling - Special feature: Various motor voltages for worldwide employment - Other motor.

The Pfeiffer Adixen Pascal 2005 SD Rotary Vane Pump is a versatile dual-stage vacuum pump that is compact and used in many industrial, scientific and research applications. The universal single-phase motor can be disassembled independently from the pump for easy vacuum pump oil changes Integrated gas ballast valve extends the field of applications Compact diaphragm pump with a pumping speed of up to 0.7 m 3 /h For mains voltage: 90-127 V, 50 Hz, respectively 187-265 V, 60 H The pumping of air or process gases can cause moisture/vapour to condense in the pump. This has an effect on the attainable final pressure and the volume flow rate levels. The rate of expulsion of condensate can be increased by admitting gas ballast air and the pump will attain the specified final pressure within a shorter time. This is achieved by setting the sleeve 43 on gas ballas valve to the position "open" (Y)

Properly using a gas ballast valve as found on a mechanical oil sealed vacuum pump has been considered by some to be an arcane art and practiced blindly much of the time. Actually, gas ballasting is a very simple operation and when properly applied can keep vacuum pumps in optimal conditions even when used in wet processes that can potentially contaminate the oil with condensation. When vacuum. Pfeiffer Vacuum scroll pumps from the HiScroll range. Excellent water vapor tolerance thanks to the two-stage gas ballast. As a result, condensation in the vacuum pump is avoided. With these features, the pumps are ideal for use in many applications in analytics, biomedicine, pharmaceuticals and research and development This operating manual is for customers of Pfeiffer Vacuum. It describes the func-tioning of the designated product and provides the most important information for • Gas ballast valve with dosable flushing gas connection • Vane material different e t a rk a e•L ≤ 1*10-5 mbar * l/s. 8 Installatio
