3 Reasons a Gast Pump is the Best Brand for Your Manufacturing Team

A vacuum pump is a machine that works by extracting air or gas from a container (usually a tank) to decrease the pressure of a confined space. Vacuum pumps are used in virtually every industry imaginable, so the question isn’t whether your team needs them—but which manufacturer supplies the best on the market.

To put things simply, Gast is the only name you need to remember. The Gast pump is an overall superior product compared to the other name brands you’ll come across.

In this article, we’re going to talk about what you should consider when choosing new vacuum pumps and why you should go with a Gast vacuum pump. Read on to learn more.

What to Look for in a Vacuum Pump

There are several factors to take into account when looking for a new vacuum pump. The first and obviously most crucial factor is directly related to your intended use. This is what will determine the technology, vacuum level, flow rate, chemical resistance, and lubrication needed.

There are also five types of vacuum pumps you can choose from:

  1. Rotary vane vacuum pumps
  2. Diaphragm vacuum pumps
  3. Liquid ring vacuum pumps
  4. Scroll vacuum pumps
  5. Turbomolecular vacuum pumps

The type of vacuum pump you need will depend entirely on the industry you’ll be using it for. For example, the diaphragm vacuum pumps are corrosion and chemical resistant. Therefore, they’re most suitable for the food, medical, chemistry, and cosmetics industries.

The other factors you need to take into account include:

The Flow Rate

A vacuum pump’s flow rate is directly related to the machine’s overall draining time. That means you’ll need to assess the vacuum pump’s capacity to produce the volume flow rate, which is the required pumping speed, and the mass flow rate (according to your process requirements).

In general, the higher the flow rate, the shorter the drainage time.

Chemical Compatibility

If you’re working with chemicals of any kind, it’s necessary to determine the type of problems your vacuum pump may encounter. Ideally, if you are working with chemicals, you’ll start by choosing a pump designed to withstand chemical corrosion, such as the aforementioned diaphragm vacuum pump.

Overall, you’ll need to assess the types of chemicals you’ll be using and how they react with one another. Something as simple as incompatible gases can cause an unwanted reaction resulting in excessive damage.


Once again, the industry you’re working in will directly determine whether you need a dry or lubricated pump. For example, a dry pump is much more suitable in a laboratory environment, whereas a lubricated pump is needed for agricultural applications.

Additionally, a lubricated vacuum pump works much more efficiently and offers more resistance. However, it’ll also require more maintenance. So, you’ll want to determine two things: Whether you need a lubricated pump and whether lubrication is, in fact, necessary to your operations.

Maintenance and Costs

Once you’ve taken all of the above into consideration, you can then analyze the number of maintenance cycles your vacuum pump will require. This will also affect your installation costs, which are separate from the purchase price and the ongoing operational costs.
