Why Pulsafeeder PULSAR 25HL does not start?
- A
  Alex KennedyAug 18, 2025
  If your Pulsafeeder Water Pump doesn't start, it could be due to several reasons. The coupling might be disconnected, so ensure it is properly connected. There might be an issue with the power source, so check that. A blown fuse or circuit breaker could also be the cause; replace them, addressing any overload. Look for any broken wires and repair them. Verify that the pump is wired correctly by checking the wiring diagram. Finally, check for any blockages in the pipe or line and open the valves.

What to do if Pulsafeeder PULSAR 25HL Water Pump has no delivery?
- C
  Charles JacobsAug 21, 2025
  If your Pulsafeeder Water Pump isn't delivering, there are several potential causes. First, ensure the motor is running by checking the power source and wiring diagram. Verify that the supply tank isn't empty and fill it if needed. Check for clogged lines and clean and flush them. Make sure all line valves are open. Inspect the ball check valves for solids holding them open and clean them. Address vapor lock or cavitation by increasing suction pressure. If the prime is lost, reprime the pump and check for leaks. Clean the strainer, replacing the screen if necessary. For an under-primed hydraulic system, refer to Repriming the Pump.

What to do if Pulsafeeder PULSAR 25HL delivery is low?
- B
  brianchandlerAug 23, 2025
  If your Pulsafeeder Water Pump's delivery is low, several factors could be responsible. Check if the motor speed is too low by examining the voltages, frequency, wiring, and terminal connections, and comparing them to the specifications on the nameplate. Also, inspect the check valves for wear or dirt; clean them, and replace them if damaged. Other potential issues include a hydraulic bypass valve operating each stroke, a calibration system error, product viscosity being too high, product cavitating, a worn or damaged piston seal, or a leaking process pressure relief valve.

  sarahdavisAug 26, 2025
  If your Pulsafeeder Water Pump motor is overheating, it could be due to a few reasons. The pump might be overloaded, so check the operating conditions against the pump design. There could be high or low voltage, so check the power source. Also, a loose wire could be the culprit, so trace and correct it.

What causes noisy gearing or knocking in Pulsafeeder PULSAR 25HL?
- M
  Melissa KirbyAug 28, 2025
  Noisy gearing or knocking in your Pulsafeeder Water Pump can stem from several causes. The discharge pressure might be too high, so reduce it. It could also be water hammer, in which case you should install a PULSAtrol. If the hydraulic bypass valve is set too high, readjust it. Note that nondestructive knocking is characteristic of lost motion pumps when the stroke length is at a partial setting.

Why does Pulsafeeder PULSAR 25HL Water Pump delivery gradually drop?
- S
  Samuel ShortAug 30, 2025
  If the delivery of your Pulsafeeder Water Pump is gradually dropping, it could be due to several reasons. Check valve leakage could be a cause; clean the valves, and replace them if damaged. There might be a leak in the suction line, so locate and correct it. A fouled strainer could also be the problem, so clean or replace the screen. A change in the product could affect delivery, so check the viscosity. Bypass leakage or a worn piston seal can also cause this issue. Lastly, ensure the supply tank vent isn't plugged.

Why is Pulsafeeder Water Pump piping noisy?
- L
  Lauren DaltonSep 1, 2025
  Noisy piping in your Pulsafeeder Water Pump system can be caused by several factors. If the pipe size is too small, increase the size of the piping and install a PULSAtrol. If pipe runs are too long, install a PULSAtrol in line. Should surge chambers be flooded, replace the contents with air or inert gas; if a PULSAtrol is installed, replace the diaphragm and recharge. If no surge chambers are used, install a PULSAtrol.

What causes erratic delivery in Pulsafeeder PULSAR 25HL?
- P
  Philip ClaytonSep 3, 2025
  Erratic delivery in your Pulsafeeder Water Pump can be attributed to several factors. There might be a leak in the suction line, so locate and correct it. Product cavitation could also be the cause, so increase suction pressure. Entrapped air or gas in the product might be the issue. Erratic motor speed could also lead to this problem, so check the voltage and frequency. Lastly, fouled check valves can cause erratic delivery, so clean or replace them if necessary.

Why is Pulsafeeder PULSAR 25HL Water Pump delivery higher than rated?
- A
  angeljonesSep 6, 2025
  If your Pulsafeeder Water Pump's delivery is higher than rated, it could be due to a few reasons. The suction pressure might be higher than the discharge pressure, so install a backpressure valve. If a back pressure valve is set too low, increase the setting. A leaking back pressure valve could also be the cause, so repair, clean, or replace it. Lastly, a calibration error could lead to higher delivery, so review the calculations.

What to do if Pulsafeeder PULSAR 25HL Water Pump loses hydraulic oil?
- J
  Jamie PhillipsSep 8, 2025
  If your Pulsafeeder Water Pump is losing hydraulic oil, several issues could be the cause. A ruptured diaphragm could be leaking, so replace it. A leaky seal could also be the source, so replace it as well. Check for cover gasket leaks and replace or retighten them. If the pump head gasket leaks, replace it and tighten the pump head bolts, applying sealing compound. Also, if the pump head is overfilled, remove the excess oil.
