Submersible solids-handling pumps from Zoeller Company are designed to provide a long service life. Their finned castings, oil-filled housings and non-overloading windings enable the motor to maintain a low operating temperature when facing harsh conditions. They are available in 1 to 60 hp, 3- or 4-inch solids-handling capacity, and two-vane or vortex impeller styles. They are available with either a standard or explosion-proof motor. 800/928-7867; www.zoellerengprod.com.
