Where are Becker pumps made?

As Managing Director of Becker Pumps USA, Jason Rathbun recently stated “A lot of people don’t know that most of these cheap imitation vanes are made in China, and we see the results of using them every day.

What industries use vacuum pumps?

Vacuum Pumps can be used in a wide variety of industries and applications to remove air and gas molecules from a process including the food and beverage industry, semiconductor and electronics industry, pulp and paper, medical, plastics and woodworking to name but a few.

What are the two types of vacuum pumps?

There are two basic categories of vacuum pump: Gas Transfer Pumps and entrapment or capture pumps (Figure 1).

What’s the most common deep vacuum level required by manufacturers?

Since most manufacturers require that systems being repaired be pulled down to at least 500 microns, and in some cases 250 microns, using the right procedures and equipment to get the job done quickly is in everybody’s interest.

What is a rotary vane vacuum pump?

A rotary vane vacuum pump in its simplest definition is a type of pump technology that enables the compression of air inside the pump chamber to create suction for the removal of air molecules from a vessel or area. Rotary vane vacuum pump works on a positive-displacement pumping principle.

What is dry vacuum pump?

The definition of a dry vacuum pump is a pump that does not use any fluids to create a vacuum or contact the process gas and can also discharge to atmosphere. Timing gears with oil reservoirs and close clearances between the rotors and housing are additional attributes that make up a dry vacuum pump.

How vacuum is produced?

In general, a vacuum is created by starting with air at atmospheric pressure within a chamber of some sort. As molecules are removed, there are fewer other molecules for a given molecule to collide with the distance becomes longer and longer as the pressure is reduced.

Which compressor is used as a vacuum pump?

A typical characteristic of a vacuum pump is that it works with a very high pressure ratio. This explains why multistage machines are common. Multi-stage air compressors can also be used for vacuums within the pressure range 1 bar(a) and 0.1 bar(a).

Why are vacuum pumps expensive?

However, electromechanical vacuum pumps are almost always in continuous operation with vacuum requirements regulated by valves. This means that electricity consumption and, consequently, energy costs can be quite high. They also have high initial costs and ongoing maintenance expenses.

How many microns are good in a vacuum?

with a vacuum pump. Why a Vacuum Pump? ASHRAE recommends evacuation to below 1000 microns for moisture removal and below 500 microns after replacing a compressor. Some equipment manufacturers call for evacuation to 400 microns to ensure that harmful water vapor is removed from the system.
