Product Data Sheet
Thompson 6JC Pump
This pump uses an oil-lubricated two-cylinder piston compressor that is driven by v-belt off the shaft. A vacuum is created by forcing air through an air/water separator. A float-operated valve installed in the separator prevents liquid but allows air to exit the separation chamber. This pump develops higher discharge pressures than trash pumps due to the wear ring and closed impeller design.
