A Complete Guide to Choose the Best Dry Vane Vacuum Pump

Industrial applications of vacuum pumps are many and used for different purposes. Generally, the most common use of the dry vane vacuum pump is to extract the gas or air from the tank so that a complete or partial vacuum is generated in the system. In the given or confined space, the pressure is decreased gradually so that air is sucked out of the container. The extracted gas or air is then transferred to another container. Whether it is the medical industries, laboratories, food processing industries, or chemical factories, a vacuum pump is used for several applications. 

To know which type of vacuum pump is good, you need to consider some vital factors. You need to focus on the industrial application so that selection is done appropriately.

Dry Vane Vacuum Pump

The Four Major Types of Dry Vane Vacuum Pump Include:

• Rotary Vane: This is the traditional type of pump, which is smaller than other types and helps in lowering the upfront cost. This pump uses oil to operate and lubricate the parts. It is the maintenance of the oil that determines the life and efficacy of the dry vane vacuum pump with rotary vanes. Well, there are automated systems that ensure regular changing of the oil.

• Diaphragm: These are the dry pumps that create pulsing motion and open and close the valve to ensure air movement. It is the most popular option when it comes to the chemical and corrosion-resistant vacuum pumps.

• Hybrid or Combination: This type of dry vane vacuum pump has both rotary and diaphragm model. This design greatly helps in keeping the oil cleaner that further retains the efficacy of the pump parts.

• Scroll: These types of pumps use two spiral scrolls to compress the vapours and air, ensuring their movement towards the exhaust. Their operation cost is less as they do not require regular oiling and are generally maintenance-free. 

Few Things to Consider Before Buying a Dry Vane Vacuum Pump:

• The Flow Rate of The Pump: It is the draining time of the machine, which determines the flow rate of the pump. It is essential to evaluate the capacity of the pump to produce the required speed and flow rate of the pumping. Generally, if the flow rate is higher, the draining time is shorter and vice versa.

• Compatibility of The Chemicals: Another crucial factor that you should consider while selecting the dry vane vacuum pump is to find the chemical and gas compatibility that would be ideal for your industrial application. It would help in determining the possible issues that can be encountered within the device.

• Lubrication: As mentioned earlier, rotary vanes require oil for constant lubrication of the parts. Before you invest in any of the types, it is essential to know whether it is necessary to lubricate the pump or not. Lubricated vacuum pumps work efficiently and smoothly, and it requires regular maintenance. Dry pumps with the least lubrication are the major choice for laboratory applications.

• Cost and Maintenance: Apart from those mentioned above, one of the essential aspects which one should not forget about is the overall cost and maintenance. It is important to know the frequency of the maintenance cycle. If it requires quick and frequent maintenance, it can be costly for daily operational expenses.

Keep the budget factor in mind so that you can wisely invest in the best vacuum pump. Above all, keep your requirements in mind and how the industrial application would impact the production method should be considered appropriately. Seek expert’s suggestions to know the functions and features of the particular pumps and how it would benefit you.
