To properly install the Barmesa Pumps 2SEV512 series Submersible Solids Handling Pump, please follow the instructions provided in the instruction manual. Here is a step-by-step guide:
1. Receiving inspection: Upon receiving the pump, inspect it for any damage or shortages. If any damage has occurred, file a claim immediately with the company that delivered the pump.
2. Storage: If the pump is stored for more than six months from the date of purchase, it should be bench tested prior to installation. This includes checking the impeller to ensure it is free turning and conducting a run test to ensure the motor operates properly.
3. Submergence: The pump should always be operated in a submerged condition. The minimum sump liquid level should never be less than above the pump's volute.
4. Liquid Level Control: Install a level control to the discharge piping with a piggyback plug. Adjust the cord tether of the level control to change the control level.
5. Installation: These pumps are recommended for use in a sealed and vented sump or basin. Ensure that the pump is not installed in a trench, ditch, or hole with a dirt bottom, as the legs may sink into the dirt and the suction may become plugged.
6. Discharge Piping: The discharge piping should be as short as possible and sized no smaller than the pump discharge. Install both a check valve and a shut-off valve for each pump to prevent backflow and manually stop system flow during pump servicing.
7. Electrical Connections: The power cable mounted to the pump must not be modified. Connect the 3 wire cord and 3 prong grounded plug to a 3 wire grounded Ground Fault receptacle. Ensure proper grounding and use a separate, properly fused, and grounded branch circuit.
8. Overload Protection: The pump is equipped with an inherent overheating protector that will trip and shut off the pump if the windings become too hot or the load current becomes too high. In the event of an overload, the source of the condition should be determined and corrected immediately.
9. Pre-Operation: Before putting the pump into service, check the voltage and phase, ensure proper pump rotation, record the information from the pump name plate, and perform an insulation (megger) test on the motor.
10. Maintenance: No lubrication or maintenance is required for the pump. However, perform regular checks for oil level and contamination, inspect the impeller and body for build-up or clogging, and check the motor, bearings, and shaft seal for wear or leakage.
Please refer to the instruction manual for more detailed instructions and safety information.
