About Types:

At Copenhagen Pump we carry several types of vacuum pumps. GEV vane and side channel impeller vacuum pumps, Atlas Copco LRP and other liquid pumps as well as Pedro Gil capsule blowers and turbo blowers.

The table below gives a rough overview of the possible applications.

In practice, the different technologies do not compete with each other, but take over or complement each other
in different pressure and capacity ranges.

The GEV vane pump is strong in low pressure and low capacity, while the GEV side channel impeller blower is used for relatively high flow and moderate vacuum i.e. from 600 mbar absolute. The side channel impeller blower is also an excellent overpressure pump for moderate overpressures up to approx. 0.4 bar o.

The liquid pump is a more complex machine with an auxiliary system for the liquid ring. Atlas Copco LRP and GEV produce complete systems for vacuum down to 0.050 bar/50 mbar.

Pedro Gil capsule blowers builds machines for aeration and pneumatic conveying respectively.

The Pedro Gil capsule blower is a lobe profile compressor/pump. The required tolerances of the machine
do not allow more than a differential pressure of 1,8 bar 1800 mbar. In practice this means that a
overpressure of about 0.8 bar and an absolute underpressure of about 0.2 bar/200 mbar.

Objective:

The purpose of using GEV vacuum pumps in connection with vacuum technology for industrial use is typically for conveying dry substances such as sand, powder and other granulates, for vacuum evaporation of foodstuffs and for vacuum packaging.
Gas types: most often ordinary air is transported with GEV vacuum pumps, but also water vapour in connection with evaporation plants or biogas in connection with biogas production.

Value creation:

Applications:

Alcohol reduced beer, fresh water generators, evaporation plants for food, bio-tech and phama industry, vacuum transport of solids like sand, powder and granules, biogas production.
For certain tasks an objective Atex requirement is placed on the vacuum pump, such requirements for vacuum pumps are seen for example in biogas production. GEV vacuum vane pumps and side channel impeller pumps are therefore offered as standard in Atex execution.

Durability: the machines are normally made to work around the clock. I.e. 8,000 hours of operation/year with resulting programmed maintenance.

Delivery time:

Typically 2-8 weeks

Access to spare parts:

Relatively simple
