The pumps casing helps to protect the pump and motor from damage while opearting in a corrosive environment. Extensive corrosion of the pump casing can lead to perforation and allow water to enter the pump and motor.
Pump control panel is a device that provides power to the pumps in sewage wet well during the required operation modes. General operation is in an automatic mode where the level control interacts with the electrical control to indicate when power is required to the pumps. Electrical control designs and features will vary depending on the specific application.
Pump controllers are used to monitor flow and/or level variables, and control a pump accordingly to maintain the desired levels. Pump control can include simply turning a pump on and off, or more advanced controls for pump speed and output pressure. Many pump controllers include rate indication features and totalizer, data logger, and chart recorder capabilities. Some pump controllers are printed circuit boards (PCB) that can be plugged directly into a computer back plane. It differs in terms of media, user interface, and compliance.
