Above capacities and suction lift refer to pumps tested on water at 115 VAC, 60 Hz, and an ambient temperature of 70°F (20°C). Higher specific gravity fluids will reduce suction lift. Higher viscosity fluids will reduce capacity.

*Not available with bleed valve.
**SS versions use 1/4" female threads except models 0220,0420, and 0232 which use 3/8" female threads.
