Magnetic drive unit |
摘要 |
A pump (10) includes a housing (16) having an inlet port (42) and an outlet port (43). An impeller (15) is received within the housing (16) and carries a magnet (34). A motor (11) rotates a shaft (17) having a threaded end (52). A plastic driver magnetic unit (12) is formed of a magnetized material and includes a base (47) and a generally cylindrical sidewall (48). At least a portion of the sidewall (48) is magnetized. A threaded insert (49) is positioned in the base (47) of the driver unit (12) and is threaded onto the shaft (17) of the motor (11) until a stop shoulder (53) formed on the shaft (17) is engaged by the insert (49). Such aligns the magnetized portion of the sidewall (48) of the driver unit (12) with the magnet (34) of the impeller (18) such that upon rotation of the motor shaft (17), the driver unit (12) rotates the impeller (15) and fluid is drawn into the housing (16) through the inlet port (42) and transferred out of the housing (16) through the outlet port (43). <IMAGE> |
