Its motor is designed with finned castings for heat dissipation, and oil-filled housings and non-overloading windings enable the motor to maintain a low operating temperature in harsh conditions. The pump is available in 25 to 60 bhp, with 4- and 6-inch discharge units, and 3 1/8- or 4-inch spherical passing capability. An inverter-duty motor is offered as an option. 800/298-7867; www.zoellerengprod.com.
