How to fix excessive gauge vibration in UDOR ZETA 70 Water Pump?

  Robert BishopAug 18, 2025
  Excessive gauge vibration and pulsation in your UDOR Water Pump can stem from several sources. The pressure in your pulsation dampener might be either too low or too high, requiring adjustment. Another potential cause is an air leak in the inlet line, which necessitates examining hoses and fittings to ensure an airtight fit. Also, check if the strainer is too small, dirty, or plugged; consider using a larger capacity strainer or cleaning the existing one. Finally, make sure all air has been evacuated from the pump cavity by running the pump with an open discharge.

  If your UDOR Water Pump isn't building enough pressure, or the pressure drops when you open the relief valve, several factors could be at play. First, your strainer might be too small, dirty, or clogged; try using a larger one or cleaning the existing one. A restricted or collapsed suction hose can also cause this issue, so eliminate any restrictions or replace the hose if it's collapsed. Check for air leaks in the inlet line by examining hoses and fittings, ensuring they're airtight. Other potential causes include a faulty pressure relief valve (repair or replace it), excessive tank foam due to low tank volume (refill the tank), your nozzle volume exceeding the pump's capacity (check relief valve adjustment or reduce nozzle size/number), or check valves not seating properly (clean or repl...
