Why SPX Water Pump has no flow and is not priming?
- M
  Matthew DelgadoAug 15, 2025
  The SPX Water Pump might not be priming due to several reasons. The suction lift may be too high, so you should reduce the difference between the pump and suction tank level, increase the suction pipe diameter, or reduce the length and simplify the suction pipe. There could be an air leak in the suction line that needs repair. If the viscosity is very low, increase the pump speed and reduce axial clearance. Also, check if the suction strainer or filter is clogged and clear it if necessary. Ensure the pump casing is correctly installed. Finally, verify the motor's rotation direction, changing connections for 3-phase drivers or swapping the suction and discharge openings, while checking the safety relief valve location.

Why SPX Water Pump consumes too much power or becomes hot?
- C
  Clayton WilliamsAug 26, 2025
  If your SPX Water Pump is consuming too much power or getting hot, the pump speed might be too high; reduce it and consider installing a larger pump if necessary. The gland packing could be too tight, so check or replace it. Misalignment of the coupling can also cause this issue, so check and correct the alignment. If the viscosity is too high, increase the axial clearance, heat the pump, reduce the pump speed, or increase the discharge pipe diameter.

How to fix a noisy SPX Water Pump?
- M
  Michael HowellAug 29, 2025
  If your SPX Water Pump is too noisy, it could be due to several reasons. The pump speed might be too high; reduce it and consider installing a larger pump if necessary. Cavitation could be occurring, so reduce the difference between the pump and suction tank level, and increase the suction pipe diameter. High back pressure could also be the issue; increase the pipe diameter, reduce the working pressure, and check accessories like filters or heat exchangers. Check and correct the coupling alignment. Vibration of the base plate or pipings can also cause noise; make the base plate heavier and/or fix the base plate/pipe work better. Finally, damaged or worn ball bearings can contribute to the noise; replace them if necessary.

What causes rapid wear in SPX Water Pump?
- S
  Samantha EspinozaSep 1, 2025
  Rapid wear in your SPX Water Pump can be caused by several factors. High back pressure can be a culprit, so increase the pipe diameter, reduce the working pressure, and check accessories like filters and heat exchangers. Solid matter in the liquid can also cause wear, so filter the liquid. The pump running dry is another cause; correct the liquid supply, provide a level switch or dry running protection, heat up the liquid, and stop or reduce air sucking. Finally, corrosion can lead to rapid wear, so consider changing the pump materials or application parameters.

What causes motor overloading in SPX Water Pump?
- S
  Susan LeeSep 4, 2025
  Motor overloading in your SPX Water Pump can stem from several issues. High back pressure might be the cause; increase the pipe diameter, reduce the working pressure, and check accessories like filters and heat exchangers. If the gland packing is too tight, check and replace it. High viscosity can also lead to overloading; increase the axial clearance, heat the pump, reduce the pump speed, or increase the discharge pipe diameter.

What causes rapid wear of the mechanical seal in SPX Water Pump?
- Q
  qsmithSep 7, 2025
  Rapid wear of the mechanical seal in your SPX Water Pump can be attributed to several factors. If the viscosity is too high, heat the pump or install a double mechanical seal. Bad de-aerating or dry running can also cause this; fill the pump with liquid and check the position of the relief valve or top cover. High temperature can be a factor; reduce the temperature or install a suitable mechanical seal. If the priming period is too long or there's dry running, reduce the suction line, provide dry running protection, and check the maximum allowable dry running speed for the mechanical seal. Finally, if the liquid is abrasive, filter or neutralize it, or install a double mechanical seal with hard seal faces and barrier liquid.

What to do if SPX Water Pump is leaking?
- J
  jasonmolinaSep 12, 2025
  If your SPX Water Pump is leaking, it could be due to the gland packing leaking excessively; check or replace the gland packing. Alternatively, the mechanical seal may be leaking, in which case you should replace it.
