Why my Versa-Matic Water Pump will not operate?
- D
  Dylan DixonAug 1, 2025
  If your Versa-Matic Water Pump won't operate, there are several potential causes. It might be over-lubricated, in which case you should set the lubricator to the lowest setting or remove it. Another reason may be a lack of air supply, so check the air line size and length, and the compressor capacity. Worn or incorrect o-rings, debris in the air valve, or clogged manifolds could also be responsible. Ensure you clean the air valve/filter, clean suction or discharge manifolds/piping, reinstall o-rings in the correct position if they are misplaced, and check the compatibility of o-rings with lubrication. Finally, verify that the system pressure doesn't exceed the air supply pressure; if it does, increase the air supply pressure.

Why is product leaking through the exhaust of my Versa-Matic Water Pump?
- M
  Mark LawsonAug 5, 2025
  If you notice product leaking through the exhaust of your Versa-Matic Water Pump, it could be due to a diaphragm failure or loose diaphragm plates. Replace the diaphragms, check for any damage, and ensure the diaphragm plates are tightened. Another cause might be the diaphragm being stretched around the center or bolt holes, indicating excessive inlet or air pressure. Also, excessive air supply pressure can cause leaks, so ensure to tighten bolts to the recommended torque.

What causes premature diaphragm failure in Versa-Matic Water Pump?
- L
  Lauren ScottAug 10, 2025
  Premature diaphragm failure in your Versa-Matic Water Pump can stem from several issues. Cavitation or excessive flooded suction pressure could be the cause; try enlarging the pipe diameter on the suction side or moving the pump closer to the product. Misapplication due to chemical or physical incompatibility is another factor; consult the Chemical Resistance Chart for compatibility. Using the wrong type of lubrication or incorrect diaphragm plates can also lead to failure; check compatibility and ensure correct installation. Additionally, starting the pump at full air pressure can damage the diaphragm; start the pump slowly. Consider adding an accumulation tank or pulsation dampener as close to the pump as possible.

How to fix Versa-Matic Water Pump running sluggish or stalling?

  hbrownAug 14, 2025
  If your Versa-Matic Water Pump is running sluggishly or stalling, several factors could be responsible. Over-lubrication can cause this issue, so set the lubricator to the lowest setting or remove it. Icing or clogged manifolds may also impede performance; clean or replace the exhaust muffler and clean the manifolds to allow proper air flow. Additionally, deadhead conditions or cavitation on the suction side could be the cause; check the system to locate the deadhead, increase air supply pressure, and check suction by moving the pump closer to the product. Finally, ensure there's adequate air supply by checking the air line size, length, and compressor capacity.

What to do if Versa-Matic Water Pump cycles but will not prime or flow?
- S
  Sandra ConnerAug 18, 2025
  If your Versa-Matic Water Pump cycles but won't prime or flow, consider these potential causes: cavitation on the suction side, which can be resolved by moving the pump closer to the product. Also, check if the valve balls are not seating properly or sticking; clean around the valve ball cage and valve seat area. Missing valve balls, damaged valve balls or seats, or a clogged suction line can also prevent priming or flow. Replace any missing or damaged parts and clean the suction manifold and/or piping. If the fingers in the valve ball cage are worn, replace the part. Finally, check the Chemical Resistance Guide for compatibility.
