Description
Significantly increased dry-running capability!
Our SiC-X bearings can run dry for extended periods — even hours!
Unique materials and manufacturing techniques of our specially treated.
SiC-X bearings provide a coefficient of friction 1/4 that of SiC.
The very low coefficient of friction of our SiC-X bearings results in much less heat being generated in upset or dry-running conditions. SiC-X bearings are more forgiving of dry-running conditions frequently encountered at start-up, during upset conditions or in batch services.Extremely hard surfaces minimize wear and prolong service life; resistance to chemicals is maintained for extended bearing life.

Preliminary Test Results
In multiple dry-running tests using an MP220, 1 HP unit with standard SiC bearings, noise developed after a brief period of operation. On disassembly, internal damage was identified. The same pump with the special bearing material operated over 1 hour and 45 minutes with no unusual noise. On disassembly, there was no visible damage.
The next test involved running the same pump with the SiC-X bearing material dry for one hour with the suction valve closed. The rear casing temperature reached 260°F. With the pump still operating, the suction valve was then opened, allowing room temperature water to enter the pump. On inspection after the pump continued to operate, no damage or cracks were observed--all parts were in excellent condition.

A test at a customer facility was inadvertently run when the suction cap used during shipping was not removed before installation. After running dry for 10 minutes, the pump was inspected and no damage was observed. The pump was reinstalled without the cap and operated as expected.
