Why does my BIANCO PUMPZ PTFINOX45S2NXT run but have poor pressure?

  Michael CervantesAug 4, 2025
  Poor pressure in your BIANCO PUMPZ Water Pump could be due to several reasons. It might be that the flow demand is too high, or the pump isn't suited for the total head requirement. The pump itself may be worn out or damaged. Another potential cause is air entering the suction line, which reduces performance. To address this, verify that the pump is appropriate for your application, check the pump's specifications, and make sure the suction line is properly sealed.

  Catherine ChavezAug 9, 2025
  If your BIANCO PUMPZ Water Pump is running but not producing flow, or the flow is weak, several factors could be responsible. Check if any valves are closed, ensure there are no air leaks in the suction line (which could cause loss of prime), and verify that the water level is adequate. Blockages in the pump, suction, or discharge lines could also be the issue, as well as blocked in-line filters, if fitted. It's also possible that the piping is either too long or too small. You should check the suction and discharge isolating valves, look for leaks and seal any joins or fittings, and check water availability. Clean any filters/strainers in the system.

What to do if BIANCO PUMPZ PTFINOX45S2NXT is cycling on and off?

  Melissa VegaAug 14, 2025
  If your BIANCO PUMPZ Water Pump is cycling on and off, it could be due to a small water draw off or leak, a leak in the suction or discharge line, or contamination in the controller. Check for small leaks, such as from taps or the cistern, and inspect for leaks, including the suction line non-return valve.

How to fix BIANCO PUMPZ PTFINOX45S2NXT that won’t start and makes no noise?
- S
  Steven DavisAug 19, 2025
  If your BIANCO PUMPZ Water Pump isn't starting and isn't making any noise, there could be several reasons: there might be no electricity, fuses or the RCD may have tripped, there could be an internal motor fault, the static head pressure might be greater than the cut-in setting, or the controller may have sensed a dry run and is in its auto-restart cycle. First, check the power supply and see if the power LED on the controller is lit. If fuses or the RCD have tripped, this could indicate a more serious problem. Also, ensure the static water head above the controller is less than 20m. If the controller has sensed a dry run, press the reset button.

  If your BIANCO PUMPZ Water Pump is making noise but not starting, it could be due to the motor not being free to turn (internal jamming) or a faulty capacitor. Check if the pump can rotate freely.

Why does BIANCO PUMPZ PTFINOX45S2NXT run intermittently?
- F
  fryekristenAug 29, 2025
  An intermittent running BIANCO PUMPZ Water Pump may be caused by overheating and the thermal protection tripping. Make sure the water temperature is below 40 degrees Celsius and that there's enough airflow to cool the motor. Keep in mind that low voltage can also lead to motor overheating.
