Engineered with a ball-bearing supported transmission for longer service life, this pump can be run dry and handle a mixture of air and water. The Viking 32 provides maximum flow of 8.5 GPM and is self-priming up to 8ft. Similar to the Viking 16, its non-choke valves means no in-line filters are needed. Connections are 1-1/2" and this model also includes a crank for manual handling in emergencies.
