Vane pumps come in handy when you want to handle light solvents, liquefied petroleum gas or any other substance used in the lab. Buying such a pump can be a daunting task for beginners because they don't have any clues about what they should look for in the vane pump.
If you are an unsuspecting shopper, it's hard not to buy the wrong vane pump. This is because there are so many brands and types on the market. The following is a list of instructions for purchasing a vane pump for a Vickers Vane Pump .
1. Use of the pump
It is clear that there are many vane pumps available for sale on the market. But before you spend their hard earned money among them, you should consider what you plan to do with it.
In fact, vane pumps are designed for different applications. If you want to use a pump for evaporation, you should choose the model that provides the deepest vacuum, otherwise your program will get bad results.
On the other hand, pumps with moderate vacuum are ideal for filtration purposes, while pumps with very high vacuum are suitable for distillation. Therefore, understanding the specific use of the pump will help you choose the right match. Keep in mind that pumps designed for filtration cannot be used for distillation and vice versa.
2. Electric or air pump
In most cases, the vane pump will be powered by gas or electricity. Pumps that use electricity are much less expensive because they do not last long. Pumps that use gas are much better at operating costs (depending on gas cost).
In fact, pumps that use pumps tend to be more durable, probably because there is no friction between moving parts. There are even some designs that run without oil for a few days.
3. Chemical resistance
Before purchasing any vane pump, you should consider the substance used. This is because some types of vane pumps corrode when in contact with certain chemicals.
Corrosion causes the pump to wear faster. In addition, it can contaminate impurities in your material. You can avoid such problems by purchasing a chemically resistant vane pump to ensure that your material remains pure.
4. Pumping capacity
From one vane pump to another vane pump, the pumping capacity tends to change. It is usually measured in cubic feet per minute (CFM). It is widely believed that CFM decreases as the degree of vacuum increases. High CFM will help you achieve the vacuum you want in a short time.
You should also pay attention to the size of the motor. A larger motor is strongly recommended because it can handle a large number of motors. The disadvantage is that it consumes more energy than a pump that uses a small or medium motor.
When buying a vane pump, you obviously have to choose a quality and cheap model. Although the cheaper model is more portable, it will cost more in the long run because you have to replace it more often. The advanced pump is the best because it is very durable. Even if the initial cost is often high, it is only a once-and-for-all cost.
