Why Welch MP 601 E does not generate a vacuum?
- SSeth 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).
