O Series® pumps have a straight-in suction design (there is no check valve) which eliminates entrance restrictions and provides better suction performance when handling solvents and similar liquids. O Series pumps can be used as transfer pumps, clean water supply pumps, on spray applications and many other industrial uses. They provide reliable performance with few moving parts and offer savings in maintenance and efficiency. O Series pumps are available pedestal mounted for flex coupling or v-belt coupling to a power source.
