    What to do if my Corken Water Pump runs but has no flow?
    • M
      Michael HansonAug 16, 2025
      If your Corken Water Pump is running but there's no flow, start by checking that all valves are in the open position. An excess flow valve might be slugged or closed; in that case, stop the pump until the excess flow valve opens, and if the problem persists, install a new or larger capacity excess flow valve. Ensure the electric motor's rotation is correct and change it if necessary. Also, a suction pipe that is too small or restricted could be the cause, indicated by the pump’s inlet pressure dropping when the pump is started; remove any restrictions and/or increase the pipe size.

    Why does the electric motor of my Corken Coro-Flo FF060 Water Pump get hot?
    • K
      kbrownAug 20, 2025
      If the electric motor of your Corken Water Pump gets hot or the overload protection kicks out, it could be due to high differential pressure. Check the motor’s full load amperage and adjust the bypass valve setting to a lower position. Low line voltage could also be the cause; check the line voltage when in operation and ensure the motor is wired for the proper voltage, referring to the electric motor’s nameplate. The starter overload or heater might be too small, so check the motor load with an ammeter and confirm the heater size with the starter’s manufacturer. Additionally, a shorted motor could be the issue. To prevent moisture buildup in TEFC and explosion-proof motors, run the motor at least once a week until it gets hot enough to evaporate moisture.

    How to unlock a locked Corken Coro-Flo FF060 Water Pump?
    • R
      Raymond MooreAug 25, 2025
      If your Corken Water Pump will not turn or is locked, check for foreign matter inside the pump and clean it out, inspecting the strainer screen as well. A seized bearing could also be the problem; replace the bearings and grease them every three months using a low temperature ball bearing grease with a minimum rating of at least -25°F to 250°F. The lubricant used by the factory is Mystik JT-6 Low Temperature Extreme Grease. Moisture in the pump can also cause this; thaw and carefully break it loose, and check with the product supplier if the product contains water and properly remove the moisture from the product.

    Why is my Corken Coro-Flo FF060 so noisy?
    • O
      ohernandezAug 27, 2025
      If your Corken Water Pump is experiencing noise or vibration, it could be due to cavitation from poor suction conditions. Make sure all valves are open, check for restrictions on the suction piping, and clean the strainer screen. Misalignment of the coupling can also cause this, so align the coupling. A loose coupling or coupling guard can also be the culprit, so tighten the coupling and its guard. If the coupling rubber insert is worn or damaged, replace it and check the coupling alignment. Finally, worn bearings can cause noise or vibration, so replace them if necessary and lubricate every three months.

    What causes continued noise or vibration in a Corken Coro-Flo FF060 Water Pump?
    • N
      Nicole MillerAug 31, 2025
      If your Corken Water Pump is experiencing noise or vibration (continued), it could be due to a defective or wrong size bypass valve. Confirm the size of the bypass valve required for the application and inspect, repair, or replace the valve. Loose anchor bolts can also cause this, so tighten all the pump’s anchor bolts.

    Why won't my Corken Coro-Flo FF060 build pressure?
    • B
      Brittany RodriguezSep 4, 2025
      If your Corken Water Pump will not build pressure, it could be due to poor suction conditions. Check the storage tank excess flow valve and clean the filter screen. The suction pipe might be too small or restricted, so remove any restrictions and/or increase the pipe size. A bypass valve set too low could also be the cause; set the valve for higher pressure. Too much impeller clearance may also be the reason; conduct a performance test on the pump.

    How to fix leaks in a Corken Coro-Flo FF060 Water Pump?
    • P
      Patrick TuckerSep 8, 2025
      If your Corken Water Pump is leaking, it could be due to failed O-rings or the mechanical seal assembly. Inspect and replace the mechanical seal and O-rings if needed.

    Why is the capacity of my Corken Coro-Flo FF060 Water Pump so low?
    • M
      Mary HansonNov 11, 2025
      If your Corken Water Pump experiences low capacity, several factors could be at play. It could be due to the pump speed being too low because of the wrong electric motor, so check the RPM of the electric motor. A clogged strainer can also cause this issue, so you should clean the strainer screen. High differential pressure could be the culprit; in this case, remove any restrictions in the discharge piping/hose or increase their sizes. Other potential causes include a bypass valve stuck open or set too low (readjust, repair, or replace the bypass valve), a worn impeller (replace the impeller), or a suction pipe that is too small or restricted (remove restrictions and/or increase the pipe size; this is indicated by the pump’s inlet pressure dropping when the pump is started). Vapor lock can ...
