One of the most valuable services provided by Jensen Pump Stations is the day of start-up. Proper commissioning ensures that potential future issues are found before they become problems. This saves time and money down the road, when trouble shooting can become difficult. It can prevent expensive damage to equipment, and it is easier to correct these issues while the project site is in construction mode.
Before a pump technician arrives, a licensed electrician connects power to the control panel. The Jensen Pump Technician will connect all the wires from the pumps and level detection. It is important to use proper lock out / tag out procedures while completing this work.
Thoroughly documenting the completed work on the day of start-up is essential. Serial numbers, electrical ratings, and site information are all helpful in diagnosing future problems. Proper documentation also ensures that each station is commissioned using standard processes and procedures. This provides confidence to the end user that nothing was overlooked during station start-up.
Once the wires have been connected, it’s time to suit up. Electrical shock and arc flash explosions are potential hazards when working with high voltage. Workers should wear personal protection equipment that is arc flash rated per NFPA 70E. Jensen Pump Technicians wear this equipment while working on all electrically charged equipment. Here the technician checks electrical loads and proper control panel operation.
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 stormwater 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.
