Application

Vacuum pumps for the extraction of chips, dust and liquids

In extraction, the negative pressure captures chips, sawdust, dust, fumes or liquids directly at the machine and carries them through a line to the separator. Becker describes it as the extraction of mixtures of gas, liquid and solids, in which a separator protects the pump – from woodworking to the slaughter line. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 366 models from 5 manufacturers.

Operating principle

How it works: Extraction of chips, dust and liquids

The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.

  1. CaptureThe negative pressure picks up chips, dust, fumes or liquid directly at the machine – Busch describes the continuous extraction of sawdust, Becker describes extraction systems in slaughter lines.
  2. SeparationThrough the suction line, the mixture reaches the separator, which separates solids and liquid from the air and so, according to Becker, protects the pump.
  3. FiltrationA filter holds back the fine dust, and the vacuum pump releases the cleaned air to the exhaust; for wood dust, Becker names pumps with a large filter area.

Vacuum and sizing

Extraction of chips, dust and liquids: how much vacuum is needed

What the manufacturers say about pressure, pumping speed and sizing.

Which vacuum

For dust-intensive applications, Becker names 200–250 mbar (VTLF/VXLF) and 150–200 mbar (BCV).

Which pumping speed

For wood dust, Becker names VTLF/VXLF with 244–570 m³/h and BCV with 275–600 m³/h, each also in a VARIAIR version.

What determines the sizing

The mixture: according to Becker, dry dust calls for oil-free pumps with a large filter area; according to Atlas Copco, wet processes such as evisceration call for liquid ring vacuum pumps that tolerate water, blood and small parts. For slaughter waste, Busch names MINK, R5 and TYR, and in its product finder also DOLPHIN and SAMOS.

What the manufacturers point out

The separator ahead of the pump and the filter area for dust (both Becker). For foam extraction in rearing tanks, Busch describes a different approach: a water jet under overpressure destroys the foam (SAMOS, TYR).

Frequently asked questions

Extraction of chips, dust and liquids: frequently asked questions

How does extraction with a vacuum pump work?

The vacuum pump generates negative pressure at the extraction point; the inflowing air carries chips, dust, fumes or liquid with it. Becker describes extraction as capturing mixtures of gas, liquid and solids, in which a separator protects the pump. A filter holds back the fine dust, and the cleaned air leaves the pump.

Which vacuum pump for chip extraction?

For wood chips and sawdust, Becker names the BCV claw vacuum pumps; for the continuous extraction of sawdust, Busch names MINK and SAMOS. Elmo Rietschle describes collecting the chips during cutting, milling and grinding, without naming a series. Atlas Copco lists the DB side channel blowers for chips and dust.

Which vacuum pump for wood dust?

For dust-intensive applications, Becker names oil-free pumps with a large filter area: VTLF and VXLF with 244–570 m³/h at 200–250 mbar and BCV with 275–600 m³/h at 150–200 mbar, each also as a VARIAIR version.

How much vacuum does the extraction of chips and dust need?

For wood dust, Becker names 200–250 mbar for VTLF/VXLF and 150–200 mbar for BCV.

Oil-free or oil-lubricated for extraction?

For wood dust, Becker explicitly names oil-free pumps with a large filter area (VTLF, VXLF, BCV). For extraction in general, Becker lists dry-running (VT, VX, KVT, KVX, VTLF, VXLF) and oil-lubricated rotary vane vacuum pumps (O, U, U4) side by side. For wet processes, Atlas Copco describes liquid ring vacuum pumps that tolerate water, blood and small parts.

Which vacuum pump extracts liquids?

Becker describes the extraction of mixtures of gas, liquid and solids with a separator that protects the pump. For evisceration as a wet process, Atlas Copco names liquid ring vacuum pumps (AWS, LRP VSD+) that tolerate water, blood and small parts, and for condensate and paint the DB side channel blowers.

Why does extraction need a separator?

Because chips, liquid and small parts must not get into the pump. According to Becker, the separator protects the pump when mixtures of gas, liquid and solids are extracted. For slaughter waste, Atlas Copco describes a pipe network that carries it to the collection point.

What can be done if dust clogs the vacuum pump?

Check the separator and the filter: according to Becker, the separator protects the pump, and for dust Becker names pumps with a large filter area (VTLF, VXLF, BCV). A full or undersized filter lets dust through; it must match the amount of dust and be cleaned regularly.

Which vacuum pump for slaughter waste and evisceration?

Atlas Copco describes evisceration as a wet process with the AWS and LRP VSD+ liquid ring vacuum pumps. For offal and trimmings, Busch names MINK, R5 and TYR, and in its product finder also DOLPHIN and SAMOS. For bleeding, extraction and spinal cord removal in slaughter lines, Becker names U, U4 and RBP.

Can soldering fumes be extracted with a vacuum pump?

Becker names soldering fume extraction in the electronics industry as an application, without describing it in more detail or naming a series. Becker also lists industrial vacuum cleaners only as a field of use.

A single pump or a central vacuum system?

A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.

Does Ehrler & Beck also supply spare parts and service?

Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
