Questions and Answers

    Why is product leaking through the exhaust of my Sandpiper Water Pump?
    • M
      Miss Makayla FloresAug 9, 2025
      If product is leaking through the exhaust of your Sandpiper Water Pump, it could be due to a diaphragm failure or loose diaphragm plates. Replace the diaphragms, check them for damage, and ensure the diaphragm plates are tightened. Another cause might be the diaphragm being stretched around the center or bolt holes. Check for excessive inlet or air pressure. Also, consult the Chemical Resistance Chart to ensure compatibility with the products, cleaners, and temperature limitations, and to verify proper lubrication.

    What causes premature diaphragm failure in Sandpiper s05?
    • A
      Andrea OlsenAug 13, 2025
      Premature diaphragm failure in your Sandpiper Water Pump can occur due to several reasons. Cavitation might be the cause, so enlarge the pipe diameter on the suction side of the pump. Excessive flooded suction pressure can also lead to this issue, so move the pump closer to the product, raise the pump to reduce inlet pressure, install a back pressure device, or add an accumulation tank or pulsation dampener. Misapplication due to chemical or physical incompatibility is another potential cause, so consult the Chemical Resistance Chart. Ensure the correct diaphragm plates are installed correctly, and check that the outer plates haven't worn to a sharp edge.

    How to fix unbalanced cycling in Sandpiper s05 Water Pump?
    • C
      Connie MeyerAug 17, 2025
      Unbalanced cycling in your Sandpiper Water Pump can stem from several issues. If the suction lift is excessive, try filling the chambers with liquid to prime the pump. Ensure the suction line is adequately sized. Inspect for air leaks on the suction side by visually checking all gaskets and pipe connections. Also, check for obstructions in the check valve by disassembling the wet end of the pump and manually dislodging any blockages. Inspect check valves and seats for wear, adjusting or replacing them as necessary. Purge the chambers through the tapped chamber vent plugs to address entrained air or vapor lock.

    What to do if Sandpiper Water Pump cycles once?
    • C
      Cole RojasAug 22, 2025
      If your Sandpiper Water Pump cycles only once, it could be due to a deadhead situation where the system pressure meets or exceeds the air supply pressure. Increase the inlet air pressure to the pump, noting that the pump is designed for a 1:1 pressure ratio at zero flow. It could also be caused by incorrectly installed air valve or intermediate gaskets. Ensure gaskets are installed with holes properly aligned. A bent or missing actuator plunger could be the cause, so remove the pilot valve and inspect the actuator plungers.

    Why my Sandpiper s05 Water Pump will not operate / cycle?
    • A
      Aaron CollinsOct 26, 2025
      If your Sandpiper Water Pump won't start or cycle, several issues could be the cause. First, the pump might be over-lubricated, so reduce the lubricator setting or remove it, as these pumps are designed for lube-free operation. Check that the air line is appropriately sized and the compressor capacity (HP vs. CFM) is adequate. Examine the air distribution system by disassembling and inspecting the main air distribution valve, pilot valve, and pilot valve actuators. Also, ensure the discharge line isn't blocked by checking for closed valves and cleaning manifolds/piping. Increasing the inlet air pressure may help if the system pressure meets or exceeds the air supply pressure. Remove and clean the air exhaust muffler screen to eliminate blockages or ice. If fluid is present in the muffler, ...

    What to do if Sandpiper s05 Water Pump cycles sluggishly or stalls?
    • J
      Jason CoxOct 30, 2025
      If your Sandpiper Water Pump cycles sluggishly, stalls, or has unsatisfactory flow, there are several potential causes. Check if the pump is being over-lubricated and, if so, set the lubricator to the lowest setting or remove it. Icing could be a problem, so remove the muffler screen to de-ice it and consider installing an air dryer. Clean the manifolds to ensure proper airflow. Increase the inlet air pressure if the system pressure is meeting or exceeding the air supply pressure. Ensure proper suction by moving the pump closer to the product. Verify the air line size and compressor capacity are adequate. If the suction lift is excessive, try filling the chambers with liquid to prime the pump. Decrease the inlet air pressure and volume if the pump is cavitating the fluid by cycling too fas...

    Why Sandpiper s05 Water Pump cycles but will not prime or has no flow?
    • T
      Tina SandersNov 3, 2025
      If your Sandpiper Water Pump cycles but won't prime or has no flow, consider the following: Cavitation on the suction side might be the issue, so move the pump closer to the product. Check for obstructions in the check valve, dislodging any blockages and cleaning around the valve ball cage and seat area; replace damaged parts and consider using a heavier valve ball material. Ensure valve balls are not missing. Inspect the suction line for blockages, removing any obstructions and clearing all screens or strainers. For suction lifts exceeding 20 feet, try filling the chambers with liquid to prime the pump. Look for air leaks on the suction side and inspect all gaskets and pipe connections. Also, if fluid is found in the air exhaust muffler, disassemble the pump chambers and check for diaphra...
