Mechvac Series Rotary Vane Pumps

Despite being reasonably ubiquitous, rotary vane pumps may be unfamiliar to you. While they are not well-known, rotary vane pumps are essential to everyday life. Whether transferring power steering fluid in a car, ensuring the correct amount of carbonation in a fountain drink, or moving thick liquids without compromising their quality, rotary vane pumps play an essential part in the items you use.

Below you will discover information about Mechvac Series rotary vane pumps, how they function, their benefits and drawbacks, and the various varieties of vane pumps.

What exactly is a rotary vane pump?

A rotary vane pump, also known as a vacuum pump, is a self-priming positive displacement pump that uses vanes fixed to a rotor inside a cylindrical cylinder to transfer fluids and gases. The liquids and gases are compressed, pressurized, and discharged through the pump outlet. Vacuum pumps are used in various automotive applications, including power steering, air conditioning, and automatic gearboxes. Rotary vane pumps are also used in the food and beverage industry for fountain drink dispensers, espresso machines, and the transfer of viscous liquids. They feed pressured water to reverse osmosis filtering membranes in the water treatment business.

What are the applications of Rotary Vane Pumps?

In automobiles, high-pressure vacuum pumps are often employed to carry freon, power steering fluid, and transmission fluid. On the other hand, medium-pressure pumps convey water in espresso machines and carbonated beverage dispensers. Low-pressure rotary vane pumps, albeit less frequent than higher-pressure pumps, are employed in chemical vapor deposition, a method used to generate thin films for semiconductors. Other applications for vacuum pumps include:

• Dust extraction systems
• Furnaces for industrial use
• Filtration by vacuum
• Degassing
• Crystallization
• Drying by distillation

Is oil required for rotary vane pumps?

In some circumstances, oil is a valuable supplement to a rotary vane pump, although it is not appropriate for all applications. Oil serves four critical purposes in a vane pump:

• Seals located between the rotor and the vanes
• Creates a second seal between the vanes and the chamber.
• Disperses heat to cool the pump.
• Corrosion protection for components
• Oil seals vacuum pumps, making them significantly more efficient than dry-running ones.

On the other hand, oil can depart with compressed gases in a pump, rendering it unsuitable for particular uses. Oil traps help to reduce oil expulsion; however, pumps will continuously expel oil no matter how good the oil trap is.

The Benefits of Rotary Vane Pumps

Regardless of the type of vanes used, rotary vane pumps have numerous advantages.

• Durable vanes provide a longer lifespan.
• Quiet operation
• Little vibration
• Easy to maintain
• It can be used entirely dry
• Lightweight and small
• The discharged liquid is not affected by changes in viscosity.
• Low pulsation and a stable flow rate

Types of rotary vane pumps

Rotary vane pumps generally serve the same purpose, although their vanes can be of many various forms. These vane types are as follows:

Sliding – vanes slide in and out to draw liquid into the chamber through the inlet port.

Flexible: Flexible Vanes keep in touch with the rotor walls, trapping liquid as they rotate.

External – vanes are installed in the pump’s casing rather than the rotor.

Rotating: Vanes revolve inside the chamber to catch liquids.

Oscillating – vanes suck liquids in by pumping in an oscillating motion.

The most popular type of rotary vane pump is the sliding and flexible vane pump, which is utilized in various commercial applications. Sliding vane pumps are typically found at beverage fountains and espresso machines. They carry water into pressurized CO2 tanks and heat it before passing it through espresso grinds. On the other hand, flexible vane pumps are often utilized in food and pharmaceutical applications. They are good at transporting viscous liquids, such as creams, and liquids containing particles, such as yogurt, without compromising product quality.

How does a rotary vane pump work?

Two or more chambers in rotary vane pumps compress, rotate, and discharge gases and liquids. The vacuum created by these chambers pressurizes the contents, allowing them to pass through the pump’s exit. The vanes slide in and out and turn against the rotor’s inner wall. One chamber is formed when the vanes rotate, and the outlet valve separates the chamber into suction and discharges sides. The fluid enters the chamber’s suction side, compressing with each spin. When the suction chamber is complete, the contents are discharged into the discharge chamber and out of the pump outlet. Finally, an exhaust valve prevents backflow by preventing contents from reentering the pump.

Advantages Of Rotary Vane Pump?

Rotary vane pumps are positive displacement pumps that use a rotor with vanes to create a vacuum and pump fluid. They offer many advantages over other types of pumps, including:

• They are very efficient and can achieve high flow rates at low pressures. It makes them ideal for pumping viscous fluids or slurries.
• They are reliable and can handle a wide range of operating conditions.
• They are relatively easy to maintain and repair.
• Their compact size makes them suitable for tight spaces.
• They can self-prime, making them ideal for applications without an external pump.
• They can transfer liquids of various viscosities and with different solids content.
