The SP22, which has flow rates up to 250 gpm, is powered by magnetic drive technology and can provide years of sealless operation with no leaks and the ability to run-dry without damage in absence of continuous flow, Finish Thompson says.

The SP22 centrifugal pump 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.
 
Finish Thompson's pump incorporates NPT or BSP threaded flange or union connections and multiple impeller diameters (impeller trims available every 1/8-in) provide broad hydraulic coverage. The SP centrifugal Series mounts to NEMA and IEC motor frames and is suitable for sumps, underground storage tanks, rail cars, and piping systems that tend to have trapped or entrained air.
