A: The grinder pump will be owned by the drainage district, as is the pressure pipe on private property. The drainage district maintains the grinder pumps.
A motor which can be operated either on DC (direct current) or on single phase AC (alternating current) is called a universal motor. On both AC and DC, it gives approximately the same speed and output. Universal motors often run at dangerously high speed when operated at no load. This means that motor speed will be low at full load, but the speed of the motor will start increasing as the load on the motor decreases.
The electric DC motor has two basic parts: the rotating part that is called the armature, and the stationary part that includes coils of wire called the field coils. The stationary part of the electric dc motor is also called the stator. Figure 12-1 shows a picture of a typical DC motor, Fig.
