Why Welch MP 601 E does not generate a vacuum?
- S
  Seth SmithAug 9, 2025
  Your Welch Water Pump might not be generating a vacuum due to several reasons: the connected apparatus or connecting elements could be leaking, the vacuum pump itself might be leaking (in this case, check the hose connections between the pump heads, and replace hoses or fittings if needed), the pump head could be leaking, the diaphragm might be defective, a valve could be defective (consider exchanging the valve), the vacuum pump could be dirty (perform general maintenance and cleaning), or the valves could be dirty (clean condensates and foreign objects out of the valves).

  If your Welch Water Pump isn't starting, it could be due to a few reasons: there may be no power supply, the motor could be defective, or the pump body itself might be defective. For the power supply issue, consult a qualified electrician. If the motor is defective, contact a service workshop. If the pump body is defective, consider repair or exchange.
