The fully enclosed oil-filled motor efficiently dissipates heat and locks out moisture so you receive reliable pumping service • The mechanical dual seal is constructed with a ceramic stationary face and a carbon rotating face for long service life • The impeller is a two-vane semi-open design for efficient operation without clogging; the impeller has pump-out vanes to prevent material buildup around shaft and seal • The stainless steel shaft eliminates corrosion and fatigue to give longer pump life; the minimum shaft overhang decreases deflection and increases seal life.
