What to do if my IWAKI EWN-B11 VC Water Pump is leaking?
If your IWAKI Water Pump is leaking liquid, first, retighten the fitting or the air vent body if they seem loose. If the pump head is loose, retighten it. Ensure that O rings and valve gaskets are properly installed. If the diaphragm is broken, replace it. Finally, check that the discharge line is not closed or the tubing is not clogged, as excessive discharge pressure can also cause leaks.
Why does the flow rate fluctuate in my IWAKI EWN-B11 VC Water Pump?
If your IWAKI Water Pump's flow rate fluctuates, it could be due to several reasons. Air might be trapped in the pump head, so try to expel it. Overfeeding might be occurring, in which case you should mount a check valve. Foreign matter could be stuck in the pump head valves, requiring you to dismantle, inspect, and clean the valves, replacing them if necessary. A broken diaphragm can also cause this issue, so consider replacing it. Lastly, pressure fluctuations at the injection point can be a factor; maintain a constant pressure by optimizing piping or relocating the injection point.
What to do if my IWAKI Water Pump cannot pump up liquid?
If your IWAKI Water Pump isn't pumping liquid, there might be an air lock in the pump, so you should expel the air. If the stroke length is too short, run the pump at 100% stroke length and adjust it to the proper length. Also, check for air ingress through the suction line and correct the tubing if needed. Ensure that the valve set is installed correctly and that valve gaskets are in place. Finally, check for any foreign matter stuck in the pump head valves or a ball valve stuck on a valve seat; dismantle, inspect, and clean the valves, replacing parts as necessary.
What to do if my IWAKI Water Pump does not receive the external signal?
If your IWAKI Water Pump does not receive the external signal, check the wiring to ensure the signal is being sent to the pump.
