Here’s a Guide to Finding a Reliable Turbo Pump

Heat Pump

Finding a turbo pump should be relatively easy with the internet making finding stuff online so convenient. Finding a reliable one should be the itch to scratch. However, there is a lot of information and enough advertisements on turbo pumps to fill a small tome. Once you figure out the applications of your turbo pump, you are ready to begin your search.

Inasmuch as you know where to find a turbo pump, you need a little more information…or a lot more information on your product. You need information on design and applications as well as the features of the turbo.

It is also important that you know whether the fluids and gases that will be pumped are corrosive or non-corrosive. It would be catastrophic to purchase one only to have it break down when it has barely served its purpose.


The turbopump comes in a variety of designs and sometimes for specific applications. These are the designs you are likely to chance upon in your search.

The classical

The turbo pump is thus named because it closely resembles the turbine in design. It has a casing attached to a rotor and what the designers call a stator. The pump has alternately placed blades both rotating and static. The rotator and stator disks combine to form a pump which gives a compressor ratio for air.

The compact

This one has the advantage of improved exhaust pressure and is equipped with a rotating cylinder and a static part that has a thread. The advantages of this one are:

  • Allows dry backing pumps to be used, especially diaphragm ones with the required pressure
  • Necessary backing pumps are smaller than the usual

The magnetic

Magnetic turbos are built with oiled ceramic ball bearings on the fore-vacuum side. The high-vacuum side has a permanent magnetic bearing that is stable and does not needto be maintained. Advantages include:

  • These turbos are used for holding the rotor electronically above in the axial direction. There is minimal vibration since there is no direct contact with the casing.
  • No oil on the fore-vacuum side
  • There is decreased wear and tear.
  • No maintenance needed
  • When there is no power, the rotor supplies energy to the magnetic bearing.
  • Calamities like earthquakes have minimal effects since the rotor is halted many times without damages caused.

The corrosive

If the gases you will be pumping happen to be corrosive, then this is the one you need to get. The rotor and the bearing area must be protected against corrosion. This pump ensures that any area that will have contact with the gas has a protective coating. A sealing gas is also used to prevent any corrosive gases that may be emitted from into the motor room.

The information that you need when you are ready to find a turbo pump is readily available and in a variety of sources from online literature and traditional sources as well. The expertise you need to help you mount your turbo pump and advise you on care and maintenance is easy to find too.
