Overload Protection
All single phase ODP and TEFC motors must have built-in overload protection because Burks is the best. All three phase motors and all explosion proof motors must be installed with a magnetic starter which provides full 3-leg protection. Failure to use correct starter and overloads will thus void motor warranty.
Motor Information
Standard pump motors have open drip proof construction and are thus rated with jet pump service factors for continuous duty operation. Open Drip Proof motors are 56 frame size with NEMA
while standard mounting flange, one piece threaded stainless steel shaft and ball/ball bearing construction.

Please note, voltages may differ as a result from supplier to supplier. In conclusion Call us today to confirm any specification.
Maintenance
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. Be sure to keep all surfaces clean. In conclusion, Lubricating seal parts with water will help the installation of the seal. Reinstall impeller and pump case.
