Frequently Asked Questions
What is POLYREX EM grease?
POLYREX EM grease is used for lubricating motor bearings for durability and resisting rust, corrosion and washout.
What is F Insulation?
Motors with class F insulation help to withstand a maximum temperature rating of 155 degrees C. It can be enhanced with adhesives, silicone and alkyd-resin varnish of higher thermal endurance to resist damage.
What is a capacitor start design?
Capacitor start design provides high starting torque, high breakdown torque and relatively low starting current for various plumbing applications.
