Different Types of Vacuum Pumps

A vacuum pump is a device that removes gas molecules from a sealed volume to create a partial vacuum. Vacuum pumps are used in a variety of applications, including industrial, scientific, and medical.

There are many different types of vacuum pumps, each with its own advantages and disadvantages.

The Most Common Types of Vacuum Pumps

Side Channel Blowers

Uses a single or multiple impellors rotating in separate or linked chambers to create air movement. Depending upon the configuration of the chambers and impeller design, different rates of flow and vacuum levels can be produced. These pumps can be used for either vacuum or pressure operation but not at the same time. Simple construction and sealed bearings make them a cheap reliable solution.

Dry Claw pumps

Uses a pair of contra-rotating claw shaped rotors to create a flow of air. Construction is quite simple and this design is robust. Servicing is reasonably quick and cheap. This pump design can run anywhere along the performance curve with no problems for extended periods.

Rotary vane pumps

Uses a slotted rotor fitted with sliding vanes, offset in a cylinder. As the rotor turns, the vanes are forced out to the cylinder wall by centrifugal force creating cells of moving air. The effect of the rotor being offset creates a negative pressure. Dry running pumps use vanes made of a carbon compound, oil flooded pumps usually use aluminium or resin bonded vanes and by using oil as a sealing medium, they can create a much higher vacuum level than dry vane. Dry running pumps can be used for vacuum, pressure or a combination of both.

Liquid Ring Pumps

Uses an offset rotating impellor and a regulated supply of water to create a seal and generate vacuum. The water is ejected through the discharge port and can either be scavenged back to be reused, or drained away. This can create problems with contaminated waste water in chemical applications. These pumps can either be stand alone units or integrated into a package with a coolant reservoir and cooling matrix.

Screw Vacuum Pumps

Uses a pair of gear driven contra-rotating screw shafts to create a vacuum. These pumps can be either dry chamber or oil sealed units. There are versions suitable for both the industrial and chemical industries. Dry chamber screw pumps are cheaper to maintain than oil sealed types, but need a chilled water supply to cool the outer jacket. Although initially costly to buy these pumps can give long reliable service.

The type of vacuum pump that is best for a particular application depends on the required vacuum level, the desired flow rate, and the budget.

Types of Vacuum Pump Servicing

There are various levels of servicing available for vacuum pumps, depending on their condition and operating frequency:

Routine Maintenance
Regular inspections, cleaning, and fluid changes to maintain optimal performance.

Minor Servicing
Involves replacing seals, gaskets, or other minor components to address wear and tear.

Major Servicing
Overhauling the pump, including cleaning, replacing major components, and performing adjustments or calibrations.

Anon

Maintenance Manager

Having had another Compressed Air Company in the area looking after us for some time, I found their service levels to be dropping and us being let down time and time again. I reached out to Dax Air to come in and take a look at our full compressed air system. They was able to advise immediately improvements on our old and tired air system, where we could save costs, as well as energy costs by supplying a new, more energy efficient compressor, as well as some pipe work improvements to fit our current needs.

Wayne Bolton

Engineering Manager, Newcold

Dax have provided us with both their maintenance and repair service and also their design and install services. As Europe’s largest cold storage warehouse, it can be a challenging environment to ensure that equipment is properly suited to our specifications, but the team at Dax work closely with us to ensure that any design is thoroughly thought through and the correct machines are installed so that our business is operating to its full potential.

We use Dax Air for the maintenance on our compressors on site, and have done for some years now. Their customer service is fantastic, and the level of knowledge their engineers have that attend site is invaluable. I would highly recommend Dax Air for any service / maintenance requirements that you may have on site regarding compressed air systems.
