Rotary vane pumps offer a wide capacity both in the vacuum and pressure ranges and are robust enough for heavy duty applications. Depending on the processes you want to use these pumps for, you have a choice of dry running or oil lubricated rotary vane pumps and compressors – ensuring you can best benefit from the advantages of either technology. Both versions are available in single-tiered or two-tiered design.The single-tiered version is generally air-cooled whereas the two-tiered version is water-cooled.
