What type of pump is typically used in lift station wet wells?

Submersible pumps are typically used in lift station wet wells due to their efficient operation and design that allows them to be submerged in the wastewater they pump. These pumps are sealed, preventing water from entering the motor and other components, which is essential in a wet well environment where they are constantly surrounded by liquid.

The design of submersible pumps allows for effective removal of liquid from deep sump areas where gravity alone would not suffice. Because they are submerged, they also reduce the need for complex and potentially costly external pumping systems that would require additional plumbing and valve systems. This placement optimizes space and minimizes the risk of pump cavitation, as the pump inlet is always located below the surface of the liquid.

In contrast, centrifugal pumps, diaphragm pumps, and jet pumps may not be as suited for such environments. Centrifugal pumps, while common in many systems, typically require continuous priming for efficient operation, making them less ideal for wet wells where submerged operation is vital. Diaphragm pumps are generally used for specific applications that need high precision and do not perform as efficiently in the continuous operation required within a lift station. Jet pumps, on the other hand, rely on suction and can struggle with the conditions found in a wet well,
