The Pioneer Pump Vortex Series pumps from Franklin Electric pass through the most challenging solids using a recessed impeller that avoids direct contact. The pumps are suited for applications where fluid conditioning, macerating or mix-prevention is unnecessary. The vortex technology eliminates internal wetted parts, like wear plates and chopper blades, which would otherwise have to be monitored, adjusted and replaced. A range of electric and diesel packaging options are offered for fixed and portable installations and can be fitted with the Pioneer Prime vac-assist system for suction lift applications. The pumps are available in 4-by-4, 6-by-6 and 8-by-8 sizes and cover flow rates up to 3,600 gpm and heads up to 150 feet. 260-824-2900; www.pioneerpump.com
