Coupling and Drive of a standard Centrifugal Pump

The turbine is usually driven by an electric motor. The coupling between the motor and the hydraulic system is a weak point, because it is difficult to seal a rotating shaft. In connection with the clutch, which distinguishes between two types of pumps: Dry-runner pumps and canned rotor type pump. The advantage of the rider dry pump compared to the pump, canned rotor type is the use of standard motors. The disadvantage is the seal between the motor and wheel. Dry runner pump and motor shaft are separated from liquid joint, separating long-handled or magnetic coupling. In a pump with a rotor engine is smooth and separated by joints, see Figure 1.9. Mechanical seals are maintenance free and has a minor leak Fill the boxes with packing material compressed. The mechanical life shaft seals depending on the fluid pressure and temperature.
