View "FM" Approved Tables

Factory Mutual "FM" Approved gear drives are designed primarily to be used in fire protection systems.

Fire protection equipment demands the utmost reliability. DE’RAN "FM" Approved gear drives have reliability built in.

Fire protection systems spend most of their life exercising, making sure the equipment is ready and in good operating condition in case of fire. Exercises are conducted under zero or minimal thrust conditions. DE’RAN "FM" gear drives are constructed with special upthrust provisions which eliminate the possibility of damage to the equipment due to upthrust conditions, while not compromising the standard full thrust capacity of the unit.

All approved models have a -FM suffix in the model number. Each drive is marked with the DE’RAN Trademark, model number, horsepower rating, speed, gear ratio, serial number, and the FMRC Approval Mark.

All "FM" drives are assembled and tested at our modern manufacturing facility. Precision cut spiral bevel gears, anti-friction bearings, and rigid construction provide excellent service life and protection.

When fire protection equipment demands the very best, specify DE’RAN GEAR products.
