• Ball Bearings • NEMA “56C” Mount • Internal Junction Box
• Continuous Duty • 40°C Ambient • Keyed and Stainless Steel Threaded Shafts
• Open Dripproof • 60 Hz
NEMA C Face mounting bracket, and end frames are die-cast corrosion resistant aluminum, accurately machined for maximum
concentricity, and minimum runout. Stator assemblies are press fitted into rolled steel main frames. Double shielded ball bearings, selected for
quiet operation, are lubricated for life with greases specifically chosen for moisture and heat resistant qualities.
1/2” x 14 thread tapped opening is provided for conduit fitting. No external junction box required connections made under motor canopy. Motors
are supplied with horizontal canopy but are easily converted for vertical operation with the use of optional vertical canopy (#621335-002).

Important:
1. Total output (HP x service factor) of replacement motor
must equal or exceed motor being replaced.
2. The pool motors on this page are NOT equipped with a
Safety Vacuum Release System (SVRS). SVRS helps
prevent drowning due to body entrapment on underwater
drains. In some pool configurations, if a person’s body
covers the drain, the person can be trapped by suction.
The SVRS turns off the pump if this occurs.
Depending on your pool configuration,
a SVRS may be required to meet local, state, and federal
requirements.
