Industrial manufacturing heavily depends on vacuum and pressure supplied by pumps and compressors – and compressed air is as important. There a number of applications to be found in most industries, such as pick and place operations, pneumatic conveying, central vacuum systems or drying and forming. Bulk and fluid transfer are another important area of our business.
We place great emphasis on providing professional after sales support to make sure our customers can derive maximum benefit from using our pumps and compressors.
Plastic material that has been melted and degassed in the extruder is processed into continuous profiles on the calibrating table. Typically, these profiles are made into pipes or various technical profiles for windows, cable ducts, medical tubing, etc. The plastic material is suctioned into a mold. For cooling and lubrication purposes, a film of water is generated between the inside of the mold and the continuous workpiece and is continuously extracted by the vacuum pump.

Compressed air, commonly called Industry's Fourth Utility supplies power for many different manufacturing operations. It supplies motive force, and is preferred to electricity because it is safer and more convenient. For the production line Gardner Denver offers pneumatic tools convenient for industrial production because they have a low weight-to-power ratio.

The material leaving extruders is very hot and must be cooled immediately, either by means of compressed air or with water. In the latter case, side channel blowers are used to blow dry the plastics.
Water Jetting cutting systems are an environmentally-safe method for cutting through even the hardest of surfaces.
Production units for rubber parts used in the automobile industry require vacuum to evacuate the die casting moulds, to avoid air bubbles and to accelerate the rubber mass.
Plastic granules are subjected to varying temperatures in storage and when being transported. Through the condensation of the atmospheric humidity on the surface of the granules, moisture may be absorbed by capillary action, depending on the time of year, the weather conditions and the type of plastic involved. For high quality end-products, the maximum limits for moisture in the granules must not be exceeded. In basic systems, drying is performed by hot air dryers, while more efficient plants employ dry air dryers. In the latter case (and by contrast with hot air drying), the processing air is carried in a closed circuit and is directed through the material (granules or powder) for the purpose of drying it. A dehumidifier (molecular sieve), positioned in the return airflow, removes the moisture in the atmosphere. In this way, a constant flow of pre-dried air is always available in the approach to the dry silo. The air is conveyed by a blower. Most modern dryers have two drying agent containers so that the processor need not interrupt the drying process in order to regenerate the moisture-laden drying agent. Regeneration is likewise performed by a blower.
Champion offers reciprocating and rotary screw air compressor systems, parts and service. Performance ranges from 1.8 to 255.6 cfm.
Pre-expanded polystyrene beads are first blown into a mould by a side channel blower and then pressurized with steam. Finally, they are polymerized and “baked“ into moulded parts. To prevent deformations during this process the parts must be cooled. A vacuum applied to these parts ensures that they retain their shape and that the water evaporates in a flash. The heat necessary for the evaporation process is drawn out of mould and work piece, thereby speeding up cooling.
During processing, thermoplastics are melted in an extruder and degassed in the extruder's screw section. A vacuum is used to extract gaseous and vaporous components from the melt. All low-molecular substances are extracted to obtain optimal quality thermoplastic with a smoother surface, more strength, better insulating properties and a lower offgassing rate.

Manufacturing high quality, dependable gear, centrifugal, chemsteel and rubber impeller pumps for use in industrial, marine and chemical applications.
Pneumatic conveying is an efficient and economical material handling option to mechanical alternatives.In a vacuum conveying system, a blower or vacuum pump generates a partial vacuum in the material container and the granules are carried along with the air flowing through the line. The conveyed material is collected in a receiver hopper. A filter prevents the granules from penetrating into the blower or vacuum pump. Pressurized conveying systems consist of a compressor, a material storage tank, a pressurized conveyor tank (or cellular wheel sluice) with a push-type material feeder and, at the end of the conveying line, a container with dust collecting filter.
Sterilization of various devices and equipment is a vital necessity in all medical practices, hospitals, laboratories and pharmaceutical facilities. Sterilizers run through 3 distinct cycles:
In this application, the moisture from the filtrate receiver of a vacuum filter is collected and fed back into the system. If a system upset occurs, such as the failure of the filtrate pump, slugs of liquid can carry over into the vacuum system. Soft solids from the filter can also enter the vacuum system. In both cases, the liquid and soft solids will not damage the liquid ring vacuum pump, improving the overall reliability of the vacuum filtration system. A variety of seal liquids compatible with the process vapors may be selected in order to minimize contamination of gases extracted during the filtration process.
In this application, vacuum pumps are used to maintain a prime in cooling water systems. Maintaining a prime allows water circulating pumps to maintain design water flows with minimum power consumption. Single stage liquid ring pump packages, often supplied with priming valves, are ideal for this application because they prevent ingesting of water slugs into the pumps.
Raw timber is treated to prevent decay in unprotected environments. In order to do this, the wood is loaded into large, air-tight vessels. Once loaded, liquid ring pumps are used to draw vacuum on the tank to extract water vapor from the wood. Chromated Copper Arsenate (CCA) is then injected into the tank. The pumps are now used as compressors to pressurize the tank and to impregnate the wood with the desired concentration of CCA.
