Submersible Solids Handling and Grinder Pumps from Zoeller Company have finned castings, oil-filled housings and non-overloading windings that enable the motor to maintain a low operating temperature when facing harsh conditions. Solids handling pumps are available in 1 to 100 hp, and have a 3- or 4-inch solids handling capacity with two-vane or vortex-impeller styles. Grinder pumps are available in 1 to 7.5 hp, and have a star cutter with shearing action that keeps the cutting surfaces clean and assures the user of a clog-free pumping unit. They are available with either a standard or explosion-proof motor. 800/928-7867; www.zoellerengprod.com.
