STI MOTOR PRODUCTS:

Motors have a cast iron endbell 
Most "C" face motors manufactured today use die cast aluminum that is not conducive to use with centrifugal or regenerative turbine pumps.  This relatively soft metal can easily be distorted either  during assembly, transit or installation thus causing premature failure or rubbing of pump components.  Sometimes threads are stripped as well.  The SXFUHUA end bells are specifically designed to circumvent this problem by using a cast iron material that does not distort when mounting bolts are torqued to appropriate tension.

Customers report that they run cooler and quieter than comparable US manufactured motors.
Large cooling vents are incorporated into this end bell both to minimize fan noise and to provide extra cooling flow to compensate for installation into tight enclosures or cabinetry sometimes found in OEM applications.      



These motors are shorter than US manufactured motors.
These motors are designed for use in tight places.  They are shorter  than comparable motors manufactured for pumping applications.  They are unique in small size and compactness.  

Motor horsepowers are 1/3-1/2-3/4 and 1
Motors are currently available in single phase 1/3,1/2,3/4, and 1 Hp, rated 60/50 hertz, 3450 RPM, 115/208-230 Volts.

Reversible.
Motors are reversible by changing 2 wires.

Conduit connection
This new pump motor design requires no external conduit box to use up valuable cabinet space.  Connections are made inside the end bell opposite the pump where the starting capacitor is also located for best use of space.  A Conduit connection is strategically located to allow "hard" or "soft" connections depending on customer requirements.

Shaft Carbon steel/316 stainless steel friction welded.
FINALLY, a pump motor becomes available that standardizes on 316 SS shaft material for the ultimate in usability.  Most small pump motors use low cost 303, 304, 416 or other lower grade materials which limit the variety of fluids that can be pumped.  The SXFUHUA pump motors are unique in offering this highly corrosion resistant shaft material as standard.  This is new in the motor and pump industries.

Perpendicularity and concentricity are 100% checked and are guaranteed to be half NEMA 0.002 (NEMA standard is 0.004)
