How to Solve Motor-X Dosing Pump Common Faults?

Troubles & Solutions

During metering and conveying in industrial production and processing, Motor-X dosing pump may cannot work normally due to some reasons and affect industrial production. We have summarized the reasons and solutions for faults such as the mechanical dosing pump cannot be displayed or started, fail to suck liquid, and unstable capacity. This will help you quickly troubleshoot dosing pump problems and better serve industrial production.

The Motor-X dosing pump is demonstrating how the pump works.

Common Faults & Troubleshooting

Fault	Possible Causes	Correction Method
Pump cannot displayed or started.	Wiring error	Check and correct wiring
	Wrong voltage	Set the right voltage by nameplate
	On/off button damaged	Replace the button.
Pump cannot suck liquid.	The liquid suction end is not sealed well.	Check whether the seals and quick links are in good condition.
	Wrong valve assembly	Check and reassemble the valve according to the instructions.

	Foot valve blocked.	Clean filter plate and foot valve.
	Pump head blocked or impurities	Clean pump head and components
Unstable capacity	Impurities in pump head	Clean pump head and components.
Unstable capacity	Diaphragm damage	Replace diaphragm
Lower capacity	Impurities in pump head	Clean pump head and components
	Outlet pressure is too high	Check nameplate and replace dosing pump with higher pressure.
	Liquid viscosity is too high.	Please contact the manufacturer, change high viscosity check valve if necessary.
	Driven unit damaged	Return to factory for replacement.
Larger capacity	Small outlet pressure	Set a back pressure onto the outlet pipe or change one smaller capacity pump.
Liquid leakage	Upper and lower valve nuts loose	Tighten nuts.
	Pump head becomes loose	Tighten bolts. M/HX: 2.16 N.m
	Diaphragm damage	Replace diaphragm
	Seal part missing	Replace the seal part.
	Seal parts or pump head is corroded.	Please contact the manufacturer.
