Pump apparatus having a wear end and a pump end is provided with a seal-pump for preventing liquid being pumped from entering the wear end. An internal pump is positioned between the wear end and the pump end of sealless pumps to direct small quantities of gas from the wear end to the pump end at a pressure which prevents liquid in the pump end to pass into the wear end. A seal is provided on a stationary ring of the internal pump which prevents fluid being pumped from contacting working portions of the internal pump.

A device is provided for measuring bearing or shaft wear in an apparatus utilizing a rotating shaft positioned in a bearing. A plurality of magnets are mounted on the rotating shaft and at least three coils forming at least two pairs of coils are mounted on a stationary housing surrounding the shaft. Means are provided for measuring the change in induced voltage for each pair of coils independent of shaft rotation speed, ambient temperature, the flux density of the magnets and the concentricity of the bearing and shaft diameters.
