Motor Information
WT3A Series also have NEMA Jet Pump Motors. WT5 & WT5X Series consequently have rugged Swimming Pool type motors with oversize ball/ball bearing construction. All motors have open-drip proof construction and are also rated with standard NEMA Jet Pump service factors for continuous duty operation at all ratings shown. Voltages may differ from some suppliers therefore Consult factory. Overload Protection: All single phase motors have built in overload protection. All three phase motors must be installed with a magnetic starter which provides another full 3-leg protection. Failure to use correct starter and overloads will void motor warranty. All Single Phase Open Drip Proof Motors Are especially relevant due to U.L. Recognized.

Overload Protection
All 56 frame, single phase motors, open drip proof, totally enclosed and explosion proof have built-in overload protection. All three phase motors must be installed with a magnetic starter which thus provides a 3-leg protection for the motor. Furthermore, failure to use the correct starter and heater coils will thus void warranty.
Shaft Seal
The mechanical shaft seal should be replaced if liquid is noticed around the motor shaft. Remove case and impeller. Using two screwdrivers to pry on each side, remove seal stationary seat. Clean seat area of frame, install new stationary seat with ceramic surface facing out and slide new rotating element over shaft with hard carbon surface against ceramic seat. Hence, be sure to keep all surfaces clean. Lubricating seal parts with water will help the installation of the seal. In conclusion, reinstall impeller and pump case.
