Metering pumps and troubleshooting common faults


The reason


Security does not drain

1.Suction height is too high
2.Suction pipe plug
3.Suction pipe leak
4.Liquid air cylinder

1.Reduced installation height
2.Discharge blockage
3.Pinch pipe joints
4.Trying to drain the air

The discharge amount is less

1.Suction pipe partial blockage
2.A foreign body stuck check valve
3.Check valves closed lax
4.Higher viscosity of the liquid

1.Dredge suction pipeline
2.Clean the check valve
3.Replace check valve
4.Switch factory production of high-viscosity metering pump
