  If your KNF Water Pump isn't transferring, there are several potential causes: * **No voltage:** Check the room fuse and switch it on if necessary. * **Overheating:** Disconnect the pump and allow it to cool down. Identify and resolve the cause of overheating. * **Blockages:** Inspect connections and lines for any blockages and remove them. * **External valve/filter issues:** Check external valves and filters. * **Condensate in pump head:** Detach the condensate source and flush the pump. * **Worn valves:** Replace the diaphragm and reed valves (valve plate).

  If the flow rate, pressure, or vacuum is too low on your KNF Water Pump, consider these possible causes: * **Condensate in pump head:** Detach the condensate source from the pump and flush the pump. * **Pressure Imbalance:** Change the pressure conditions if there's gauge pressure on the pressure side along with vacuum or excessive pressure on the suction side. * **Insufficient cross-section:** Disconnect the pump to check output values. If needed, eliminate throttling and use larger lines or connection parts. * **Leaks:** Ensure tubes are correctly placed on hose nozzles, replace leaky tubes, and eliminate any leaks. * **Jammed connections:** Inspect connections and lines, removing any obstructions. * **Soiled Head:** Clean the head components. * **Worn valves:** Replace th...
