Magnetic coupling vacuum pumps RVM: maximum efficiency in vacuum technology

Better productivity, lower production costs, minimum maintenance. Three concepts which all industry wants to hear, and which become a reality in all vacuum processes thanks to the new magnetic Roots RVM vacuum pump developed by Pedro Gil.

Indeed, we have designed this turbo booster to reduce or eliminate the most common difficulties in using standard vacuum pumps. Let’s lift the lid and look in depth at the technology of the Roots RVM.

Sealed closure is the key

“To improve the performance of standard vacuum pumps, we must pay attention to leaks. And that means working on the seals. Eliminating dynamic seals and substituting them for magnetic coupling, we have been able to reduce leakages to the lowest level in the current market. And this has rocketed the potential of this pump, converting it into a booster turbo”.

José Orantes, director of the Vacuum Sector in Pedro Gil.

In fact, the rate of leakage is reduced extraordinarily with this type of magnetic closure, and this allows reaching a range of pressure from 10^-2 mbar up to 10^-5 mbar. This range means a much improved performance in the high vacuum zone.

But that’s not all.

Reduced maintenance

“Another of the advantages of magnetic coupling is that it significantly reduces maintenance costs. Firstly, because there are no clasps which maintain the closure, which is static and leakproof. Since there is no friction with other pumps, the coupling system is less aggressive. And the better the sealing, the longer the useful life of the equipment.”

Furthermore, the magnetic Roots RVM vacuum pump is perfect for use with a frequency shifter which allows increasing the pumping speed from 100 to 15,500 m3/h. Increases in speed of up to 50% can be reached under specific conditions. And all of this serves to increase efficiency and performance in industrial processes.

Neither is cooling water necessary and it is suitable for use in a clean room. And the possibility of a flange coupling with any kind of motor, as well as with directed horizontal or vertical liquid flows if required converts it into the most versatile and adaptable pump on the market.

Which industries can take most advantage of the new magnetic pump?

Every industry which requires the pumping of material which contaminates wastewater will see an improvement in the process with a magnetic pump. The same applies to deaeration processes.

That is why industries in the food, pharmaceutical and chemical sectors have shown interest in this new development, which they also need for their freeze-drying, distillation, concentration and filtering processes as well as packaging.

Metalization also requires operations in a vacuum, and so this pump will help to improve efficiency in the electrical, mechanical, metallurgical and plastic industries.

Even in the optical industry it is necessary to generate a vacuum for the application of fine layers in the production of optical material.

This is an investment with quick amortization thanks to cost savings and the increase in performance achieved, the quicker where there the industry is more dependent on a vacuum process, and independently of whether a constant or intermittent vacuum is required (for example in the packaging of products).

In this way, Pedro Gil again contributes to the industrial sector providing an innovation which takes the vacuum process to a different level of efficiency, capability and cost-effectiveness.
