BUSCH DOLPHIN vacuum pump

BUSCH DOLPHIN are water ring vacuum pumps offered by BUSCH. This series is based on decades of experience in the use and further development of water ring vacuum pump technology. Their proven performance allows for nearly isothermal (cool) compression, which is particularly beneficial for sensitive or hazardous gases. Additionally, they are the ideal solution for challenging applications, such as the evacuation of saturated gases and vapors.

The DOLPHIN series offers a wide range of sizes and configurations, including single-stage or two-stage models, with options for direct integration of the motor or assembly on a base. This allows for precise customization of pumps and compressors to specific process conditions, ensuring optimal performance.
