The illustrations above depict a typical pump with ball valves and clamp-on valve
covers. Alternate construction threaded style valve covers may be used on some
models.
The service procedures outlined in this manual are intended to describe the more
commonly used type of pump. Other configurations and minor design differences may
exist with different pumps. Some procedures may require slight adaptations as a result.
