It is also important to remove the pumps from the wet well to inspect for proper operation. The primary function verified is the rotation of the pumps impeller. Some inspectors rely on an audible or physical manifestation of a pump spinning backwards. This is problematic because many pumps show little to no vibration when running backwards. That is why it is critical to visually verify proper rotation. While the pumps are topside, the technician can also inspect the condition of the pump. Damage to wires, casings, and impellers can be identified.
Submersible pump stations are often critical junctions in wastewater and storm water collection systems. End users should have the confidence that the station will operate reliably for years to come. Thorough commissioning services can provide this confidence.
