Understanding Franklin Electric and Its Submersible Designs
Franklin Electric has built a complete line of pumping solutions used across residential, commercial, agricultural, and industrial applications. Franklin Electric offers a lot of solutions for water and wastewater treatment, with an extensive range of products and services to meet diverse needs. These pumps are engineered for groundwater distribution, water treatment, and a range of other industries.
A submersible pump includes a sealed motor and a wet end that moves water through impellers. Designed for durability and long service, these units address common challenges like corrosion, overheating, or sand abrasion. Preventive maintenance ensures pumps continue to operate efficiently after they are installed.
Why Reliability Matters
Submersible pumps are installed deep in wells and boreholes. Retrieving one in the event of a breakdown can be expensive. That’s why reliability is a priority. By following maintenance schedules, recording measured values, and using dedicated service tools, customers avoid emergency downtime.
Pre-Maintenance Safety
Before any inspection:
- Disconnect power using lockout/tagout procedures
- Depressurize water lines and open valves
- Wear insulated gloves and goggles
- Gather components like a megger, torque wrench, and seal kits
- Review the Franklin Electric AIM (Application, Installation & Maintenance) manual
Safety procedures protect both the equipment and the technician performing service.
Routine Inspection Checklist
Visual & Surface Hardware
- Inspect power cables for cuts or water entry
- Check clamps, couplings, and surface pumps for corrosion
- Examine exposed line hardware for rust
Electrical & Insulation
- Test insulation resistance with a megger
- Measure the resistance of the start and run windings in motors
- Look for overheating marks on connectors
Seal & Fill Fluid
- Inspect seals for wear and leakage
- Check the filling liquid color and condition
- Replace degraded service components
Hydraulic Elements
- Inspect impellers and diffusers for erosion
- Confirm shaft alignment and proper movement of water
- Remove debris or buildup from wet-end parts
Preventive Maintenance Practices
Preventive schedules keep pumps at peak reliability. Franklin Electric recommends:
- Quarterly: insulation resistance checks and log electrical values
- Semi-annual: inspect seals, flush debris, clean impellers
- Annual: full inspection, fluid replacement, seal renewal, hydraulic testing
Lubricating bearings (if present), using VFD soft starts, and monitoring current draw expand pump life and protect components.
Franklin Electric’s support team is available to help with maintenance questions, troubleshooting, and system setup.
Troubleshooting Common Problems
Overload Trips
Caused by faulty capacitors, shorted windings, or moisture in motors. Test and replace service parts as needed.
Low or No Output
May result from blocked impellers, stuck valves, or insufficient suction. Inspect submersible pump hydraulics and electrical controls.
Excessive Noise or Vibration
Often caused by cavitation, sand, or worn impellers. A 1/2 hp or 2 hp submersible pump is often quieter than traditional jet pumps, making it suitable for residential applications where noise is a concern. Clean and recalibrate the pump line to restore quiet operation.
Overheating
Low groundwater levels or poor cooling flow can overheat motors. Always determine water depth before restarting.
Seal Failures
Abrasive particles wear down seals, causing water intrusion. Replace seals promptly to avoid larger failures.
Advanced Maintenance Considerations
For commercial and industrial applications, advanced monitoring helps:
- VFD integration to reduce mechanical stress
- Monitoring current unbalance (keep below 5–10%)
- Calibrating pressure sensors
- Benchmarking pump performance curves
- Using thermal modeling to protect motors
It’s also important to regularly monitor the HP (horsepower) rating of submersible pump motors to ensure they deliver optimal performance, especially in demanding applications.
These engineered methods expand service intervals and improve reliability in demanding industries.
Maintenance Schedule Summary
- Monthly: log amps, temperatures, inspect cables
- Quarterly: insulation checks, pressure readings
- Semi-annual: seal inspections, impeller cleaning
- Annual: full overhaul and testing
Keep a maintenance log of dates, observed issues, and corrective services.
