The Series 'EO3/4' pump benefits from proven design features gained through over 30 years of experience in developing Chemically Resistant vertical pumps. The unique design of this pump includes a chemical duty motor with an integrated, extended SS shaft specifically designed to fit the plastic sleeved impeller. This eliminates weak shaft connections, pump bearings, spindles, bushings and liners, resulting in a Chemical Duty pump which can run dry indefinitely, providing years of trouble-free service. Standard models are entirely molded in either CPVC, PP or PVDF and include a PTFE vapor seal and column labyrinth seal to protect the motor.
