  If your Wacker Neuson Power Pump isn't taking in water, several factors could be the cause. First, ensure there's enough priming water in the housing. Check that the engine speed is properly adjusted and not too low. Inspect the strainer for any blockages and clean it if necessary. Examine the suction hose for damage and repair or replace it if needed. Also, verify there are no air leaks at the suction port by ensuring the fittings are tight and the housing cover O-rings are sealing correctly. Confirm that the pump isn't positioned too high above the water source. Clear any debris that may have accumulated in the pump housing. Finally, check the clearance between the impeller and insert.

  If your Wacker Neuson Power Pump is taking in water but has little to no discharge, the issue could stem from a few reasons. Make sure the engine speed is adequately adjusted. Check the suction strainer for partial blockages and clean it thoroughly. Inspect the impeller for wear; you may need to adjust the clearance by adding shims or consider replacing the impeller altogether. Lastly, examine the volute insert for wear or damage, adjusting the clearance or replacing the insert as necessary.

  If the impeller of your Wacker Neuson Power Pump won't turn and the pump is hard to start, it might be jammed or blocked. Begin by opening the pump cover and cleaning any dirt and debris from inside the pump housing. Also, the impeller and insert might be binding; try adjusting the clearance by removing a shim from behind the insert.
