Oilless Pump

Oilless vacuum pumps are also considered compressor pumps that work oil-free. These dry pumps vacuum are quieter, lighter, and easier to move. They are also easy to maintain and rarely break down. The majority of our pumps are quiet, but many believe the oilless pumps are the quietest available.

Environmentally Friendly
Oilless pumps are also environmentally friendly, since no special oil, traps, or oil filtration accessories are required.

More Efficient And Versatile
An oil-filled vacuum pump typically requires the use of traps, which require a lot of attention and maintenance, leading to speed losses. On the other hand, oil-free vacuum pumps are capable of delivering full pumping speed without any breaks, at all times.Oilless pumps tend to be more portable, compact, and lightweight when compared to their oil-filled counterparts. They are also more flexible, as they can be used for pumping a variety of materials, including hydrogen, helium, solvents, and water vapor. They can also operate in any orientation, including sideways, or even upside down.

Hassle-Free Operation
Oil-filled pumps require a lot of maintenance and attention, including oil changes at regular intervals. On the other hand, oilless vacuum pumps are virtually maintenance-free and much easier to repair.

Dry vacuum pump
The dry vacuum pump refers to the vacuum pump that is not suitable for any oil and liquid in the pump cavity and can discharge air directly, such as claw pump, reciprocating piston pump, screw pump, oil-free rotary vane pump, etc.

The claw type oil-free vacuum pump
Belongs to the variable volume vacuum pump, and uses the multi-stage claw type rotor in series, so it can maintain the compression ratio, speed and dynamic balance for a long time. The compression ratio of claw pump is higher in high pressure area because of less counter current along the axial direction. The suction and exhaust port of claw pump is arranged on the end wall of the pump cavity, which is convenient for multi-stage connection and has smooth air passage.

Roots type vacuum pump
Roots type vacuum pump uses two 8-shaped rotors to rotate in the pump shell for vacuumizing, which is generally used as a booster vacuum pump, and its principle is similar to roots blower.Roots vacuum pump is divided into ordinary type and direct exhaust type. The ordinary roots vacuum pump needs to be directly connected with the front-end mechanical pump to discharge into the atmosphere, while the direct air roots vacuum pump does not need to connect with the front-end mechanical pump.

Oil free reciprocating vacuum pump
The reciprocating vacuum pump uses the reciprocating linear motion of the piston in the cylinder to vacuumize, and the piston is driven by the crank connecting rod mechanism through the motor. The oil-free reciprocating vacuum pump adopts self-lubricating materials. There is no need to add lubricating oil to the piston ring, sealing ring and cylinder to realize the oil-free inside the cavity. In addition, an oil separation chamber is added between the cylinder and the body to further prevent the leakage of lubricating oil in the body from entering the cylinder and prevent the pump chamber from being polluted by oil.

Vacuum Level
The pump selection heavily depends on the level of vacuum that needs to be obtained. Typically, the different pressure ranges in vacuum technology are defined as follows:Rough vacuum (from 10 3 mbar to 1 mbar).

Impact Of The Process On The Pump
Dependent upon the application area and medium to be pumped, the choice of pump(s) will vary. For example, rotary vane (RV) pumps are suited for a wide range of low and medium vacuum applications, including research and development, analytical instruments, industrial and coating activities, freeze drying, process engineering and many more.The use of oil as a sealant and coolant allows for very good pumping performance and suitability for many applications, including where dirt, dust or condensates might be present.

Pump Impact On Application
Evaluating the impact of the vacuum pump on the application or process is just as important. There are several variables that can influence the choice between different types of vacuum pumps, including - but not limited to:Oil or hydrocarbon emission.

Investment And Maintenance
As well as considering what needs to be achieved, initial capital costs, operating costs and maintenance needs should be assessed.Taking two high vacuum pump technologies, turbomolecular pumps (TMP) and oil diffusion pumps, as examples, it is fair to state that the initial costs for TMP usually will be significantly higher compared to an oil diffusion pump. However, considering the cost of ownership over a five-year period, oil diffusion pumps might cost more due to higher energy and maintenance costs. For some products, economic advantages might apply from a certain pump size/performance class.

Check the oil level regularly
Regularly check the oil level of your vacuum pump to make sure it has enough oil to keep the pump running properly.

Change the oil & filters regularly
Changing the oil in your vacuum pump helps to keep the pump running in top condition and reduces wear on the internal components. So, when do I change my vacuum pump oil?After a 100-hour break-in period of pump operation.

Regularly inspect and clean your vacuum pump
This includes checking for signs of wear, tear, and potential damage, as well as cleaning the interior and exterior of the machine. Ensure that all components are properly lubricated and that there are no blockages or obstructions in the system. One of the main ways to do an internal cleaning of particles and sludge build-up in mechanical pumps is using flushing fluid. Using FF Grade Flushing Fluid as part of your regular pump maintenance will ensure your vacuum pump is free of contaminants. The low viscosity helps free contamination from internal parts and discharge it through the drain valve.

Inspect the surrounding environment
Vacuum pumps require the right conditions to operate at peak performance. In some conditions, the pump has a greater chance of breaking down and creating a halt in operations. In order to optimize productivity, you should be aware of this.The airflow around your pump can be critical to its performance. Are there any other contaminants in the area - vapors, solvents, acid - that could be of concern? If so, determine whether they are impacting your pump's integrity and performance.

Check the Vacuum Pump for Leaks
Before using your vacuum pump, you should check for any possible leaks. Inspect all connections, hoses, and seals for tightness, and check for any signs of cracks or damage. Eliminating leaks can prolong the

life of your pump and improve the quality of work it produces.
