Why choose the Century Electric Motors over any other pool pump motors? What are the benefits?
The Century Pool motors are highly durable and easy to install, no other replacement pump motor comes close to a superbly crafted Century pool and spa motor. PLUS The -- NEW -- Triple Seal protection feature is designed into the pump end of the motor to protect the bearings from water, pests and debris, extending the life of the motor.

• Triple Seal Protection was developed to combat premature motor failures associated with pump end bearing failures due to water ingress
• Triple Seal Protection is a robust design that protects the pump end bearing on both the outboard and inboard facing seal of the bearing using three distinct sealing systems
• While Triple Seal Protection is designed to protect the pump end bearing from general water ingress, dust and debris, it is not designed to protect against leaky pump seals, constant spray from irrigation systems, or other extraneous conditions
• Seal Protection is another line of defense from moisture intrusion into the pump end bearing system
