Premium Stainless Steel Motors Offered by Leeson
LEESON Electric now offers a full line of Premium Stainless Steel motors specifically designed to meet the demanding sanitation requirements of the food processing industry. The motors are designed to withstand corrosive washdown solutions containing caustic lye, bleach, acids, alkalines, and surfactants. These motors are also well suited for use in demanding chemical processing or clean-room applications.
To withstand corrosive washdown environments, all exterior surfaces of the LEESON Premium Stainless Steel motors - frames, endbells, mounting base, fan guard, hardware, conduit box and cover -- are corrosion resistant 300-series stainless steel. Double-sealed bearings that are pre-lubricated with moisture resistant high-temperature grease are used on both ends of the motor.
The following features are unique to LEESON's Premium Stainless Steel motors:
o Revolutionary new conduit box design that reduces the contact area between the motor and the box to provide a tight seal at this critical location
o O-rings are used between the endbells and motor frame to form a liquid-tight seal.
o Double-lip seals are used in both endbells on TEFC motors and on the shaft end of TENV motors.
o All external seals, gaskets and O-rings are made from Viton® (Fluoroelastomer) material for superior chemical resistance.
o Hydrophobic breathers in the opposite shaft endbell and conduit box equalize pressure without allowing moisture to enter the motor.
o A full-fact etched stainless steel nameplate is blind-riveted to the conduit box, eliminating rivet holes in the motor frame.
o All Premium Stainless Steel motors include LEESON's IRIS(TM) insulation system for inverter-duty operation.
A total of 37 Premium Stainless Steel stock ratings are available from 1/2 to 10 HP and 1750 & 3450 RPM, with selected ratings available in 1140 RPM. These stock motors are configured with NEMA C-faces and mounting bases for universal mounting. Also, 1/2 thru 5 HP ratings are also stocked as C-face only designs.
