• Compact footprint design
• Simple installation, no special preparations required
• Triplex piston design provides quiet, vibration-free operation

The impeller shaft is mounted above the centerline of the casing; while the blades, although rotating concentrically, are located eccentrically with respect to the casing and the ring of liquid. The pump's axial suction and discharge ports are exposed to the void but separated by the impeller blades and the ring of liquid. As the process gas or vapor is drawn into the pump through the suction port, it is trapped between the impeller blades and the liquid ...

During the pumping cycle the gas is in intimate contact with the sealing liquid and ...

Performance data based on 68°F inlet air with 50% relative humidity and using water as a sealant at 60°F.
