What causes a Xylem e-XC to consume too much power?
- R
  Ruben YoungAug 28, 2025
  If your Xylem Water Pump is consuming too much power, consider the following: * **Head lower than rating:** This can cause the pump to pump too much liquid. Machine the impeller’s OD to the size advised by the factory. * **Cavitation:** Increase the positive suction head by lowering the pump, sub-cool the suction piping at the inlet to lower the entering liquid temperature, or pressurize the suction vessel. * **Mechanical defects:** Refer to "Defective impeller" and "Foot valve too small or partially obstructed".

What to do if liquid is too heavy for my Xylem e-XC?
- R
  Richard SanchezAug 30, 2025
  If the liquid being pumped is heavier (in viscosity or specific gravity) than the Xylem Water Pump is designed for, use a larger driver. Consult the factory for the recommended size and test the liquid for viscosity and specific gravity.

What happens if the suction inlet of my Xylem e-XC is not immersed enough?
- G
  georgefarrellSep 2, 2025
  If the suction inlet of your Xylem Water Pump isn't immersed enough, and the inlet cannot be lowered, or if eddies persist, chain a board to the suction pipe. This will be drawn into the eddies, smothering the vortex.

What if casing of my Xylem e-XC Water Pump is distorted?
- L
  Lucas FitzpatrickSep 7, 2025
  If the casing of your Xylem Water Pump is distorted by excessive strains from suction or discharge piping, check the alignment and examine the pump for friction between the impeller and casing. Replace any damaged parts.

What if shaft of my Xylem e-XC is bent?
- G
  griffinryanSep 9, 2025
  If the shaft of your Xylem Water Pump is bent due to damage from shipment, operation, or overhaul, check the deflection of the rotor by turning it on bearing journals. The total indicator run-out should not exceed 0.002 on the shaft and 0.004 on the impeller wearing surface.

What are possible electrical defects in Xylem e-XC Water Pump?
- C
  Christy ContrerasSep 12, 2025
  Possible electrical defects in your Xylem Water Pump could include voltage and frequency of the electrical current being lower than what the motor was built for, defects in the motor itself, or improper motor ventilation due to poor location.

What to do if there are mechanical defects in the drive of my Xylem Water Pump?
- A
  Ashley HammondSep 14, 2025
  If you suspect mechanical defects in the turbine, engine, or other type of drive (excluding the motor) of your Xylem Water Pump, and you cannot locate the trouble, consult the factory.

How to troubleshoot no liquid delivery from my Xylem e-XC Water Pump?
- A
  Ashley GrahamNov 17, 2025
  If your Xylem Water Pump isn't delivering liquid, there are several potential causes: * **Lack of prime:** Fill the pump and suction pipe completely with liquid. * **Loss of prime:** Check for leaks in suction pipe joints and fittings; vent the casing to remove accumulated air. * **Suction lift too high:** Check for pipe friction losses. If there's no obstruction at the inlet, the static lift may be too great. Measure with a mercury column or vacuum gauge while the pump operates. If the static lift is too high, raise the liquid to be pumped or lower the pump. * **Discharge head too high:** Check pipe friction losses and ensure valves are wide open. Larger piping may correct the condition. * **Motor speed too low:** Verify the motor is directly across-the-line and receiving full ...

What to do if my Xylem Water Pump is not delivering enough liquid?
- R
  Rhonda SmithNov 19, 2025
  If your Xylem Water Pump is not delivering enough liquid, consider these potential causes and solutions: * **Air leaks in suction piping:** If pumping water or another non-explosive liquid, and no explosive gas or dust is present, test flanges for leakage using a flame or match, or by plugging the inlet and putting the line under pressure to check for pressure drops. * **Motor speed too low:** Check if the motor is directly across-the-line and receiving full voltage. Also, check for low frequency or an open phase in the motor. * **Discharge head too high:** Check for pipe friction losses and ensure valves are fully open. Using larger piping may resolve this. * **Suction lift too high:** Check for pipe friction losses. If no obstruction exists at the inlet, the static lift might be...
