How to troubleshoot a Xylem Bell & Gossett TECHNOForce e-HV that does not power up?
- G
  garciadavidAug 3, 2025
  If your Xylem Water Pump station isn't powering up, there are several things to check: * Ensure the site voltage matches the pump station's design voltage. * Verify that the line-to-line and line-to-ground voltages are balanced by checking the incoming voltage and amperage. * Inspect the power fuses and breakers, replacing any blown fuses. Note that breakers are shipped in the OFF position. * Confirm that the pump station is properly grounded (earthed). * Check for any fault codes or fault lights on the Hydrovars and correct the identified fault.

Why won't the pumps run on my Xylem Bell & Gossett TECHNOForce e-HV station even though it powers up?

  If your Xylem Water Pump station powers up, but the pumps don't run, consider these potential causes: * Check the PLC to ensure the pumps are enabled and correct any faults. * Verify that the desired pressure isn't already satisfied, as the pumps will automatically stop if the actual pressure exceeds the set point. * Look for fault codes or fault lights on the Hydrovars and correct any faults. * Check for a tripped motor thermal protector; allow the motor to cool and then reset it. * Inspect the circuit breaker and fuses. * Ensure the transducer isolation valves are in the open position.

How to reduce excessive vibration in a Xylem Bell & Gossett TECHNOForce e-HV station?
- J
  James GonzalesAug 18, 2025
  To address excessive vibration in your Xylem Water Pump station: * Ensure all fasteners and components are properly tightened, as loose parts can cause vibration. * Verify that pump station vibration dampers are correctly installed and not missing. * Check if the pumps are running off their design curve, possibly due to an open discharge condition. * Inspect water supply lines and tanks for air or gases in the liquid and bleed the lines. * Examine discharge piping and valves for clogs and ensure isolation valves are open. * Check for excessive suction/lift conditions or friction loss on supply piping. * If the impeller is bound or worn, take the pump to an authorized repair facility. * Correct the alignment between pumps and pipes.

  If your Xylem Water Pump station continues to run even when no water is being used, check the following: * Ensure the system is not in Hand or Manual mode; put it in the AUTO position. * Verify that the system set pressure isn't beyond the station's capability. * Inspect for broken pipes or leaks and see if the system pressure decreases when the pump station is turned off. * Check for a properly installed diaphragm tank and ensure it hasn't failed or been incorrectly charged. * Examine the pressure transducers to see if the actual mechanical gauge pressure matches the pressure displayed on the VFDs and the PLC. * Look for malfunctioning check valves and assess if the system holds pressure when the pump package is shut down. Replace any faulty valves.

What to do if Xylem Bell & Gossett TECHNOForce e-HV runs but doesn't build pressure?
- T
  toddlewisNov 6, 2025
  If your Xylem Water Pump is running but not building the desired pressure, consider the following: 1. Check if the pumps are running off their design curve, possibly due to an open discharge condition. 2. Verify the pumps are running at full speed and check the panel for power status if they aren't. 3. Ensure the inlet pressure matches project specifications, as variations can affect performance. 4. Inspect for broken pipes. 5. Confirm the transducer isolation valves are open. 6. Check for sufficient NPSH and any air in supply lines. 7. Ensure the pump station is primed properly and all components are filled with water. 8. Verify correct pump rotation as indicated on the pump volute. 9. Check for closed or clogged suction/discharge valves. 10. Check that the motor is operating at...

What causes erratic cycling in a Xylem Bell & Gossett TECHNOForce e-HV Water Pump station?
- K
  Katherine ArnoldNov 22, 2025
  Erratic cycling or hunting in a Xylem Water Pump station can be due to several factors: * The pumps might be oversized for the current demand. Consider increasing the size of the bladder tank for low demand situations. * Fluctuating inlet pressure can cause cycling. Consider increasing the size of the bladder tank for low demand situations. * Leaks or broken pipes can lead to pressure fluctuations. Check for these issues and see if the system pressure decreases when the pump station is turned off. * A faulty diaphragm tank can cause erratic behavior. Check for proper installation and if the tank has been charged to the correct operating pressure. * Faulty pressure transducers can provide incorrect readings. Check if the mechanical gauge pressure matches what's displayed on the V...
