For maximum
service in the most critically clean or corrosive environments, nothing
beats LEESON's new WASHGUARD® All-Stainless Motors.
Specifically designed to meet the demanding sanitation
requirements of the pharmaceutical and food processing industries, these
motors are also ideal in severe chemical-processing applications involving
nitric acid and caustic lye. In fact, WASHGUARD® All-Stainless Motors
include IEEE 841 severe-duty features right out of the box!
Mechanical Protection
Features:
Exterior components are entirely of 300 series stainless steel, including
frame, base, endshields, conduit box, box cover and hardware. Plus, the
full-fact etched stainless steel nameplate is both adhesive backed and
riveted to eliminate entrapped water or other material. Nothing on the
motor's exterior is painted or coated in any way.
Endshields are o-ring sealed to the frame. Shaft seals, slingers and chemically
resistant nitrile and neoprene gaskets retard moisture entrance at hardware
points and around the conduit box. Multiple one-way endshield drains release
condensate and may be repositioned to accommodate any motor mounting angle.
Double-sealed bearings are pre-lubricated with moisture-resistant high-temperature
grease.

Electrical Performance
and Protection Features
WASHGUARD®
efficiencies meet EPACT mandates for non-exempt motors when tested without
shaft seals. For extra moisture resistance, windings are immersed and
cured in polyester insulating compound. And LEESON's exclusive IRIS™
Inverter-Rated Insulation System provides extra protection and long
life, especially in inverter-fed applications.
Standards and
Approvals
UL component recognized, file number E57948, guide number PRGY2. Energy
efficiency ratings are verified by an independent testing laboratory.
CSA Energy Efficiency Verification Program, report number EEV 78720-1.
Construction is CSA Certified for safety report number LR33543.

LEESON's Inverter
Rated Insulation system (IRIS™)
provides superior protection against voltage spikes induced
by variable frequency drives. This total insulation system protects
better than spike-resistant magnet wire alone. Specially formed phase
insulation, cushioned and sleeved connections (from the leads all the
way into the turns), and deep-penetrating, non-hygroscopic, high temperature
varnish are just a few features contributing to extra protection. All
this plus second generation spike-resistant magnet wire. The IRIS™
total insulation system is standard at no extra cost in all LEESON
stock NEMA three-phase motors, 1 HP and larger.
