Shielded pumps for the chemical industry: http://www.shnikkisopump.com/images/2_1.jpg http://www.shnikkisopump.com/images/2_2.jpg http://www.shnikkisopump.com/images/2_3.jpg http://www.shnikkisopump.com/images/2_4.jpg ① Wiring box – Sealed with an “O” ring to prevent external liquids from entering. ② Dry stator: Eliminates the oil pressure safety valve of oil-filled stators, and features a second layer of leak-proof isolation sleeve. ③ Flange: The center of the discharge flange is aligned with the center of the pump. ④ Bushings: Various surface treatments are available to suit applications with special liquids. The sleeve is replaced only when new wear surfaces and gaps are found during the bearing replacement. ⑤ Bearings: Different materials can be used to suit applications with special liquids. ⑥ Hollow shaft (only for standard models) – ensures proper cooling of the motor and prevents gas accumulation around the bearings. ⑦ Thermal relay: Embedded at the overheating points of the motor windings to prevent the motor from overheating. ⑧ Thrust plate: In case of emergencies, it bears the load and serves as a backup measure to provide hydraulic thrust balance. ⑨ Impeller: High-efficiency design, available in both open and closed configurations.
