Motor Windings – Superior
insu lation materials protect against
excessive moisture and contaminants to ensure prolonged motor life.
Mechanical Shaft Seal – Precision
lapped and highly polished
carbon-ceramic, stainless steel
construc tion. Internal design
guarantees continuous water
lubrication for maximum protection.
Dustproof Cover – All electrical
components are protected from
dirt, dust and insects by a dustproof
canopy. Ventilating air cannot
contaminate vital switching components. This eliminates the most
common cause of motor failure.
Balanced Rotor – Rotor is die cast
under high pressures for uniform
performance and greater efficiency;
dynamically balanced.
Heavy-duty Ball Bearings –
Permanently lubricated sealed
bearings are extensively tested to
ensure extended life and smooth,
quiet operation.
Pump and Motor Shaft – One
piece threaded shaft for positive
impeller drive and alignment. Shaft
is stainless steel for maximum
corrosion resistance.
