The cable is the power source for electric submersible pumps and represents the lifeline to a successful pumping application. Special care should always be practiced to ensure the power cable lasts and even though GPM-Eliminator pumps are built with heavy-duty industrial power cables, it is critically important to take precautionary measures to prevent damage to the outer jacket, insulation and especially the wire conductors. Whether it be during installation, operation or maintenance, cables are very susceptible to damage so check out these simple tips to ensure that you're not at the wrong end of cut cord and a failed pump!
- NEVER lift a pump by its cable! All pumps come with designed lifting points and the cable should not be used. Use proper lifting/rigging devices that are designed for the size and weight of the pump and attach them to the designated locations.
- Minimize stress on the cable by using a strain relief or cable clamp at the pump and/or near the sump. This relieves stress at the cable entry and ensures solid contact between the cable leads and the motor leads or terminal strip.
- Ensure pump does not spin during operation or when being installed or removed. This can result in the power cable wrapping around the lifting chains which causes further damage.
- Avoid running cable over sharp edges and corners, especially during operation.
- Never allow the entire cable, especially an exposed end which can occur during installation or removal, to sit in water for any amount of time.
Failure to practice these tips could result in a pump failure or worse...such as electrical shock, arc-flash/blast events and possible fires caused by overheating. To keep your pump running longer, and to keep your team and operation safe, take the extra time to ensure that your submersible pump power cable is properly secured and protected AT ALL TIMES!
