Up To Speed: One Small Solution Will Prevent Many Future Headaches
Up To Speed is a concise, technical blog compiled by industry veteran Mark Reeder. It provides an interesting fact, answers a thought-provoking question, or offers a cliffhanger from an actual site visit by one of our world-class Field Service Engineers.
“The best way to deliver groundwater is still with a submersible motor and pump. As you know, a submersible installation can be a tough environment. Even in the best of installations, things that are simply out of your control can go wrong, such as: water levels can drop, electrical power can intermittently go bad, and pumps can become clogged. All of these things can quickly damage the unit downhole and lead to that frantic 'we’re out of water' call from the homeowner or farmer.
A Simple Solution for Your ‘Toolbox’
The above phone call doesn’t have to happen if you employ a slightly different, yet still cost-friendly approach. My tip for you: More times than not, the best investment you can make isn’t just in the product itself, but rather what you do to protect it. Your customer has invested a lot in you and their water system. A small additional investment in a Pumptec product will help ensure you won’t have to see that motor and pump for a very long time. They’re happy and you can focus on new installations.
Have You Met Pumptec Yet?
The Franklin Electric family of Pumptec, QD Pumptec, and Pumptec-Plus make protecting a submersible installation easy. It’s been proven in our industry for years, but I’m still surprised at how underutilized it is, costing thousands of dollars in damaged motors and pumps and headaches for contractors. To begin with, the entire Pumptec family protects against a dry well condition. Since submersible pumps are water lubricated and submersible motors are water cooled, any out-of-water condition in the well can make things even worse by damaging both. Pumptec products continually monitor the load on the motor and detect if it has become 'underloaded' or is not working as hard as expected. If that occurs, within three seconds, Pumptec will shut the system off and wait for the well to recharge (you get to choose how long).
Other conditions such as a flow restriction, a deadhead condition, or even a gas-locked pump will also cause a motor underload. The Pumptec family safeguards against these issues as well, saving the pump and motor from damage.
At the opposite end of the spectrum, a bound, tight, or clogged pump will create an overload condition on the motor. Once again, Pumptec protects the installation from any further damage by taking the motor offline within three seconds.
Underload and overload conditions are both mechanical issues, but what about electrical issues? Bad power can be a real problem, especially in rural areas. Voltage has no impact on the pump, but the motor must have the proper voltage. If it’s too high or too low, the motor will be damaged and eventually fail. Pumptec to the rescue. It continuously monitors the voltage going to the motor and if that voltage is off more than 10 percent either way, it removes power from the motor until the voltage returns to normal.
What is the Difference Between Them?
Pumptec and QD Pumptec look different, but the functionality of each is nearly identical. The only difference is in the packaging. Pumptec uses a QD Control Box enclosure and wires in minutes into either a 2- or 3-wire installation. QD Pumptec installs inside a QD Control Box in literally seconds. Pumptec-Plus adds capability up to 5 horsepower and has some added features, such as the rapid cycling detection that might occur with a water-logged pressure tank.
Underload, overload, undervoltage, and overvoltage can occur in any submersible installation. Franklin Electric’s Pumptec family protects against them all, making your job easier and less stressful for a very small additional investment.”
Now, you’re up to speed.
