Cooling and lubrication of the thrust bearing assembly and carbon brushes is provided by a mixture of water and glycol. Squirrel-cage rotor mounted on Kingsbury self-centering thrust bearing. Stator housed in an airtight stainless steel casing (canned-type) with both flanges and shell in AISI 304L stainless steel. Motor lead connection allows for fast and easy maintenance. Motor suitable for use with variable frequency drive (30Hz – 60Hz). The capacitor is placed in the Noryl cartridge directly connected to the motor, so the motor does not require an external control box. Thermal protection included in the motor.Standard FeaturesAll PEARL 2 WIRE motors are provided with a removable cable connector. This solution allows fast assembly/disassembly of the pump end and makes easier maintenance operations.Kingsbury type thrust bearing unit consisting of tilting pads made of highly-resistant stainless steel and machined using spherical lapping process; this machining guarantees high reliability and high resistance to axial load to this strategic component.Die cast Aluminum rotor with shaft end made of Stainless Steel AISI 431.Running capacitor inserted in a case made of high density plastic material, electrically isolated by epoxy resin.General Features• NEMA 4” Flanges• Protection IP68• Insulation class FOperating Limits• Cooling flow: min. 0.2 m/s (0,66 ft/s)• Voltage tolerance: ±10%• Max. motor startings per hour: 20• Max. immersion depth: 984 feetBuild Components • Internal and external sleeve: Stainless Steel AISI 304• Stator: Stainless Steel AISI 304L• Shaft: Stainless Steel AISI 431• Upper bracket: Cast iron• Bracket cover: Stainless Steel AISI 304• Lip seal / Gasket: Rubber NBR• Gasket: Rubber NBR• Lower bracket: Cast iron• Diaphragm: Rubber EDPM• Capacitor case: Plastic Noryl• Thrust bearing: Stainless steel-graphite• Valve: Stainless Steel AISI 304• Cable: Rubber EDPM• Connecting plug: Stainless Steel AISI 316• Sand slinger (fixed-removable): Rubber NBR• Bolt and screws: Stainless Steel AISI 304• Cooling liquid: Antifreeze + waterKingsbury type thrust bearing unit consisting of tilting pads made of highly-resistant stainless steel and machined using the spherical lapping process.From 0,5 HP to 1,5 HP: 2000N ( 3000N in the 1,5 HP 60Hz version)Stainless steel AISI 304 with a special process of surface hardening and polishing of the working area of the brushes.
