Finish Thompson Inc.’s new self-priming SP 22 Series centrifugal pump with deep-lift and fast prime capabilities is the largest self-priming model in the line with lifts up to 25 feet and fast priming time of up to 18 ft in 90 sec. When the pump is shut off, the gooseneck design of the suction passage retains fluid in the priming chamber for fast re-priming. Powered by magnetic drive technology, the SP Series provides years of sealless operation with no leaks and the ability to run-dry without damage in absence of continuous flow. With flow rates up to 250 gpm, the SP22 is presented as a viable option for price conscious customers considering more expensive ETFE lined ductile iron self-priming pumps. The SP Series is designed for reliability even in difficult applications. It features corrosion resistant construction, high working pressure capability to 90 psi, energy saving high operating efficiency, and up to 1.8 high specific gravity handling ability.
