Puma Roots pumps are dry-running vacuum pumps that are used together with backing pumps in all rough and fine vacuum applications where large suction volumes are required.
This document provides technical specifications and application information for the Busch Puma WP series of roots pumps. These are dry-running vacuum pumps designed to be used in conjunction with backing pumps (such as oil-lubricated rotary vane or dry screw pumps) for rough and fine vacuum applications requiring large suction volumes.
The maximum permissible differential pressure varies by model, ranging from 30 hPa to 80 hPa.
