The KB series vacuum pumps belong to the family of reliable rotary vane vacuum pumps produced by Busch. These pumps are characterized by their small size and high efficiency and they are designed for installation in vacuum and vacuum-pressure casting machines. The main parameter determining the usefulness of this pump as far as casting is concerned is its efficiency measured in m³/h. The higher this value is, the larger flask can be cast while maintaining the highest quality of casting. All pumps are equipped with a powerful air filter to protect the blades of the device.
