Can the emulsification of the gearbox oil in a diaphragm metering pump cause the pump to fail to deliver fluid? If so, what are the reasons?

Oil emulsification in metering pumps is rare – is water being pumped using a diaphragm metering pump? The seal ring is leaking, allowing the medium being transported to enter the oil chamber.

Lubricant emulsification: It will rise to the surface; as long as there is oil in the area around the plunger, that’s sufficient

Gearbox oil emulsification may be caused by water ingress

I asked the wrong question; it should be hydraulic oil emulsification

If hydraulic oil is emulsified, first check whether the diaphragm is damaged; replacing the oil will resolve the issue.
