Leeson Threaded Shaft TEFC Three Phase Less Base Jet Pump Motors
TEFC Pump Motors
General Specifications:
Rugged, three phase jet pump motors for industrial service. NEMA 56 C face. Stator impregnated with heavy varnish system. High temperature copper magnet wire for high overload capacity. Grounding provision inside oversized gasketed conduit box. 380 alloy aluminum endplate with cast bearing seat insert. Neoprene shaft flinger to repel moisture and other contaminants. Mechanical bearing lock, shaft end, controls axial movement. UL and CSA recognized design (UL file No. E57948).
Shaft Material:
303 stainless steel, threaded.
Bearings:
203 Double-sealed ball bearing, shaft-end; 203 Double-shielded ball bearing, switch-end. Shaft-end bearing is locked to limit axial movement of the shaft.
Electrical Specifications:
Explosion-proof motors have automatic overload protection. Others have no thermal overload protection.
