Liquid Ring Vacuum Pumps: 30-75 HP Single & Two Stage

Single stage pumps, with a “1” prefix, range from 30 to 75 HP. They are economical choices for medical and laboratory vacuum, as well as other medium vacuum applications, such as poultry evisceration and soil venting. They are equipped with nodular iron impellers and mechanical seals.

The 2 stage models are ideal for deeper vacuum applications such as poultry packaging, drying, and vacuum filling. The 260 and 275 include mechanical seals and bronze impellers.
