- Air-cooled configurationThe V-VL series is air-cooled as standard, enabling easy installation and reliable operation at a low operating temperature.
- Low operating temperatureThe construction is designed for cooler operation, helping reduce the risk of condensation and supporting stable process conditions.
- Shaft seal for bearing protectionThe shaft seal protects the bearings from aggressive vapors and process media and contributes to a longer pump service life.
- Fresh-oil lubricationA thin film of fresh oil lubricates the vanes, seals clearances and flushes aggressive substances and process contaminants from the pump.
- No inlet or outlet valvesThe valve-free design reduces the possibility of sticking, clogging and failure in demanding processes with sticky or reactive media.
- Modular constructionThe modular design simplifies servicing, system adaptations and integration of the pump into more demanding process packages.
