Single-Stage Liquid Ring Vacuum Pump A Series
The MD Kinney A Series is a single-stage, axial flow liquid ring vacuum pump built for continuous, heavy-duty industrial vacuum service. The axial flow design allows the pump to operate fully flooded without damage — unlike flat-plate designs that are susceptible to cavitation — making it ideal for the most demanding industrial conditions. A Series pumps are oil-free, vibration-free, and environmentally friendly, with no oil used for lubrication and no oil discharged to atmosphere. It is not unusual for A Series pumps to run 24/7 operations for years without maintenance. All manufacturing is performed in Springfield, Missouri, USA.

LOREM IPSUM
An Experience Focused On You
Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
