Rotary vane vacuum Pump Cartridge Seal styles are some of the most popular vacuum pumps that are used in today's manufacturing world and in day to day activities.
They are commonly placed in industrial vacuum environments which include packaging, thermal forming, hospital systems and vacuum handling applications.
One of the features that make rotary vane vacuum Pump Cartridge Seals popular is the simple construction of the vane pumps. Due to the simple construction of the vane Mechanical Cartridge Seals they are commonly inexpensive to manufacture. What is really nice is that even though they are fairly inexpensive they are a good value to anyone needing to use a vacuum Mechanical Cartridge Seal.
There are two different types of rotary vane vacuum Mechanical Cartridge Seals. One of them is a lubricated Pump Cartridge Seal. The other type is a non-lubricated Pump Cartridge Seal which is commonly referred to as an "oil free" Pump Cartridge Seal. Both of them operate using the same type of principles, but are used for different types of applications. This is probably one of the most important principles to understand and if you select the wrong one you could end up with a broken down vacuum Pump Cartridge Seal.
Let's take a look at the two different types and of vacuum Pump Cartridge Seals. The first one is the lubricated Pump Cartridge Seal. One of the obvious reasons for choosing oil lubricating rotary vane vacuum Mechanical Cartridge Seal is because the use of the vacuum Mechanical Cartridge Seal requires a higher vacuum level. The reason an oiled Mechanical Cartridge Seal can achieve a higher vacuum is because the oil in the Mechanical Cartridge Seal creates a liquid Cartridge Seal between the vane and Mechanical Cartridge Seal housing.
The non-lubricated vacuum Split Cartridge Seal is capable of generating a vacuum level of 27 in. There are oil free models that offer slightly higher vacuum levels, but fundamentally 90% is about as much as you'll get. In the non-lubricated Split Cartridge Seals, air slippage occurs between the vane and the Split Cartridge Seal housing. With that the air leaks back between the vane and the Split Cartridge Seal housing and therefore make it so that a higher vacuum can never be accomplished.
Most of the time people think they want a vacuum Split Cartridge Seal with the highest vacuum Split Cartridge Seal level as possible. Sometimes that isn't always the right thing to get. A couple of questions that you will want to answer before making a decision are: What exact vacuum level is required and what is the application? These two questions should help you determine if you need and oil-free Split Cartridge Seal or one that is oil-lubricated.
There is much more information, but this helps you get a basic start on how the rotary vane vacuum Split Cartridge Seal works and a couple of things you can answer to decide what you need.
