A Two Stage Rotary Vane Vacuum Pump operates on a simple yet effective principle. It consists of a rotor with vanes, housed inside a cylindrical chamber. As the rotor spins, the vanes slide in and out, creating chambers that suck in and expel air. This action creates a vacuum. The “two-stage” in its name refers to the pump’s operation. In the first stage, the pump creates a moderate vacuum by removing most of the air from the system. In the second stage, it removes the remaining air to create a high vacuum. This two-stage process allows the pump to achieve a deeper vacuum than single-stage pumps. One of the key advantages of Two Stage Rotary Vane Vacuum Pumps is their efficiency. They can achieve higher vacuum levels and have faster pumping speeds compared to other types of vacuum pumps. This makes them ideal for applications that require high vacuum levels or rapid evacuation of air. Another benefit is their versatility. These pumps can handle both dry and wet gases, making them suitable for a wide range of applications. They are commonly used in industries such as food processing, pharmaceuticals, and electronics manufacturing. Despite their powerful performance, Two Stage Rotary Vane Vacuum Pumps are known for their compact design and ease of maintenance. Their simple construction makes them easy to service and repair, reducing downtime and maintenance costs. In conclusion, the Two Stage Rotary Vane Vacuum Pump is a testament to the power of engineering and design. Its ability to create high vacuums efficiently and reliably makes it an invaluable tool in many industries. As technology continues to advance, we can expect these pumps to become even more efficient and versatile, further solidifying their place in the industrial landscape.

What is a Two-Stage Rotary Vane Vacuum Pump? A Two-Stage Rotary Vane Vacuum Pump is an oil-sealed vacuum pump used in many laboratory, scientific and production vacuum systems. These pumps have both a high and low-pressure vacuum stage, which improves the vacuum pump performance. The rotor chambers are lubricated with a specifically formulated oil which acts as a sealant and lubricant between the sliding vanes, pump rotor and stator. Most laboratory rotary vane pumps are direct drive coupled pumps and typically get to a base pressure of near 1 x 10-3 torr (1.3 mbar).Get more news about Two Stage Rotary Vane Vacuum Pump Seller,you can vist our website! pumping action works on the principle of reducing the gas by gradually increasing the pump volume within the pumping cavity. The vanes rotate inside the stators and slide within the rotors. They are sealed by a specifically formulated, low vapor pressure oil, which acts as a sealant, lubricant, and coolant for the vacuum pump (You can find the right oil for your pump here). The two-stages are the high pressure and the low pressure. Gas enters the inlet or suction chamber (high pressure stage) and is transferred to the low-pressure stage where it is immediately compressed by the vane of the rotor and expelled to atmospheric pressure. The second stage improves base pressure or vacuum level of the pump. What are the Advantages and Disadvantages of using Two-Stage Rotary Vane Vacuum Pumps? When compared to a single-stage oil-sealed rotary vane vacuum pump, two-stage vacuum pumps create lower vacuum levels, along with higher volumetric flow rates over a wider pressure range. The pumping speed is essentially the same for both pumps in the rough vacuum range, but as the absolute pressure passes 1 Torr, the two-stage vacuum pump continues to maintain its pumping speed, whereas the single-stage vacuum pump starts to decline. Based on the graph provided, a single-stage pump would be adequate for vacuum levels down to about 1 Torr and would be lower cost (about 30% to 50% less. On the other hand, the performance of a single-stage vacuum pump begins to decrease after 1 Torr, so a two-stage pump becomes the obvious choice. The graph shows typical pumping speeds of single and two-stage vacuum pumps with and without the gas ballast valve open. Why is a Gas Ballast Valve Necessary and When Should I use it? Using a gas ballast is helpful when pumping contaminants like water vapor, acetone, alcohols, and other condensable vapors. A gas ballast valve admits air into the vacuum pump to assist in discharging condensable gases before they condense inside the pump. This process protects the vacuum pump, but it will decrease the performance of the pump as seen in the graph provided above. What is the Right Vacuum Pump Oil for Two-Stage Rotary Vane Vacuum Pumps? If your vacuum pump is always getting contaminated, requiring you to change the oil often, 19 Grade is the best vacuum pump oil option for you. This vacuum oil is the lower-priced option but still has a premium performance. This is a higher viscosity, designed for direct-drive rotary vane vacuum pumps, and ideal for most general-purpose applications. The low vapor pressure reduces system back streaming and thermal stability provides resistance to oxidation and sludge formation. 20 Grade is an upgraded oil from the 19 Grade. It is a severely hydro-treated paraffinic oil that is double distilled through a molecular distillation process to remove light end fractions. 20 Grade is highly saturated and contains less than 0.01% sulfur similar to technical white oils. Its high molecular weight and viscosity index provides longer service life and reduced build-up of varnish and carbonized oil on the internal pump components. If you want your oil to last a long time so you don't have to spend time changing it, Elite Z is the option for you. This oil is double distilled to exhibit the highest performance for mechanical pumps. EZ Grade is a full synthetic hydrocarbon vacuum fluid that is very resistant to thermal and chemical attacks and provides longer oil life and superior protection to the vacuum pump.
