What to do if Nordson Power Pump stops or fails to start?
- K
  Kristin PerezAug 21, 2025
  If your Nordson Power Pump stops or fails to start, several issues could be the cause. First, ensure that compressed air is being supplied to the pump at the correct pressure. Next, check the air intake screen for clogs and clean it if necessary. Also, inspect the air valve shifting mechanism and repair or replace it if faulty. Finally, check the high-pressure fluid lines for any blockages. If there is no hydraulic pressure reading on the gauge, check the high pressure fluid lines for blockage.

Why is the spray pattern fading or narrowing with the Nordson Power Pump?
- R
  Rebecca ScottAug 23, 2025
  A fading or narrowing spray pattern in your Nordson Power Pump could be due to several reasons. Ensure the pump has an adequate air supply. Check the hydraulic system for blockages at the filter, heater, guns, nozzles, fluid tips, or circulation valve and flush the system to resolve any blockages. If the pump capacity is exceeded, reduce the nozzle size or the number of guns in use, or consider adding another pump. Also, check for leaks in the air motor or valve seals and replace any damaged seals.

What to do if Nordson Power Pump strokes irregularly when gun is triggered?
- A
  Amanda OlsonAug 25, 2025
  Irregular strokes in your Nordson Power Pump when the gun is triggered can be caused by several factors. Start by purging air from the hydraulic system. Then, perform the flushing procedure to address a potentially clogged or worn ball check valve inside the pump. Next, check the air motor and valve operation for leaks, and repair or replace parts as needed. Ensure the air volume to the pump meets the requirements specified in the manual. Finally, inspect the hydraulic system for any partial blockages at the heater, fluid filter, gun, nozzle, or fluid tip, and clean or repair as necessary.

Why is the Nordson Power Pump output below specifications, or why does it surge?
- J
  jeremyjohnsonAug 26, 2025
  If the Nordson Power Pump's output is below specifications or the pump surges, it could be due to a few reasons. The material being pumped might be too viscous, so try to lower its viscosity. Also, the circulation or drain valve could be defective; disassemble and clean the valves, repairing or replacing parts as necessary. Finally, the nozzle size or the number of guns in the system might exceed the pump's capacity, so decrease the nozzle size or the number of guns, or add another pump if needed.

How to fix tails appearing in spray pattern of Nordson Power Pump?
- A
  Alison OliverAug 28, 2025
  Tails appearing in the spray pattern of your Nordson Power Pump can be due to a few reasons. You can try increasing the air pressure to the pump to address low hydraulic pressure. If the material viscosity is too high, lower it by adding solvent or heating the material, if possible. Finally, inspect the nozzle or fluid tip for damage and replace if necessary.

What to do if Nordson Power Pump does not siphon properly?
- S
  Steven GibsonAug 29, 2025
  If your Nordson Power Pump isn't siphoning correctly, check the siphon hose, rod, and strainer for blockages, loose fittings, or holes. Clean or replace parts as necessary. Also, check the siphon ball check to ensure it is not stuck or clogged; remove the ball check and clean or replace it. Make sure the material supply is above the level of the siphon strainer, and check the air valve and motor operation for defective seals, disassembling and replacing the seals if necessary.

What to do if Nordson Power Pump discharges material into solvent chamber?
- C
  Christina EllisAug 31, 2025
  If your Nordson Power Pump is discharging material into the solvent chamber, it's likely due to a worn and leaking upper packing gland. To resolve this, disassemble the hydraulic section and replace the packing gland.

What to do if Nordson Power Pump does not stroke when circulation valve is open?
- B
  Brian NunezSep 2, 2025
  If the Nordson Power Pump does not stroke when the circulation valve is open, flush the system with a compatible solvent or cleaning solution because the circulation valve might be clogged or the hydraulic system is blocked.

What to do if Nordson 25B Water Pump fails to start or stops?
- A
  Alexa AlexanderSep 3, 2025
  If your Nordson Water Pump fails to start or stops and won't restart, several factors could be at play. First, ensure there's an adequate compressed air supply by checking the drop-leg drain valve and the air regulator. A blockage in the fluid system could also be the culprit; check each component and hose, working downstream from the spray device to the pump to identify and clear any obstructions. Alternatively, the air valve spool might be stuck, or the shifter mechanism could be damaged; try moving the shifter push rod with a screwdriver, and inspect/repair the shifter mechanism or rebuild the air valve. Finally, worn air valve seals can cause this issue; in this case, remove and rebuild the air valve.

Why is my Nordson Water Pump operating but flow is restricted?
- D
  Diane SalasSep 5, 2025
  If your Nordson Water Pump operates but the flow is restricted, or the pump surges, there are several potential causes. First, check for air leaks in the air motor or air valve. An inadequate supply of air can also cause this issue, so check for restrictions in the air lines, regulator, or filter, and ensure the air lines are correctly sized. Additionally, a blockage in the hydraulic system or coating material that is too viscous can restrict flow; in the first case refer to problem 1, in the second case add solvent to the material to lower the viscosity. A leaking drain valve or spray devices exceeding pump capacity can also cause flow restrictions; check the drain valve for leaks when closed, and reduce the spray device nozzle size or number of devices connected.
