Introduction
Starting up a pump is a straightforward process (if done the right way) that can help to prevent unnecessary downtime and problems. Every pump installation is unique, and there are varying requirements for the pumps depending on the application. Below is a general guide to help ensure the safe and successful start-up of a pump.
Step 1: Verify That The Pump Is Ready To Operate
Before starting up the pump, one should take a moment to inspect the equipment and verify that the pump is ready to operate. This includes making sure that all connections are secure, the pump is correctly aligned and the drive coupling is correctly installed in accordance with the manufacturers instructions. All safety devices should be checked, including the pressure switch and safety interlocks. Lastly, any insulation or blankets should be removed from the pump or piping.
Step 2: Prime The Pump
In most cases, it is necessary to replenish the prime before starting the pump if the system has been out of service for a number of days or weeks. Priming the pump involves replenishing the clearances in the pump with liquid, such as water, allowing the pump to “pull” the liquid through it until the entire system is full of liquid.
Step 3: Verify The System Is Closed & Fill With Liquid
Once the pump is primed, the system should be fully closed by properly tightening all valves and verifying that the system is full of liquid. This will help to ensure that the pump does not have a cavitation issue, which could damage the impeller or cause a dangerous situation.
Step 4: Start The Pump
Once all of the above steps have been completed, the pump can be started. The pump should be started in accordance with the manufacturer’s instructions, taking into account any special requirements for the type of pump in question.
Step 5: Run The Pump at Its Maximum Speed
Once the pump has started, it should be run at its maximum speed to ensure that the motor is operating correctly. This will help to ensure that the motor is running within proper operating parameters and that the pump is not wasting energy or running inefficiently.
Step 6: Adjust The Pump Speed As Needed
Once the pump has been running at maximum speed, it can be adjusted to the desired speed. Depending on the type of pump, this can be done manually or through a variable speed drive, such as an inverter.
Conclusion
Starting up a pump properly is an important part of any system installation. By following the steps outlined above, one can help to ensure that the pump is operating at peak efficiency and that it is safe to operate. This can help to save time and money, as well as a great deal of headaches down the road.
