CAUTION
Verify the chemical compatibility of the pump wetted parts and the substance being pumped, flushed or
recirculated. Chemical compatibility may change with temperature and concentration of the chemical(s)
within the substance being pumped, flushed or recirculated.
The pump should not be used for the structural support of the piping system. Be certain system compo-
nents are properly supported to prevent stress on the pump parts.
Do not allow pump to operate dry for long periods of time; this may cause unnecessary wear or damage
to the pump.
Maximum temperature limits are based upon mechanical stress only. Certain chemicals will significantly
reduce maximum safe operating temperatures. Consult Graymills for chemical compatibility and temper-
ature limits.
SAFETY PRECAUTIONS
United States Government safety standards have been adopted under the Occupational Safety and Health Act. You should
consult these standards—particularly the General Standards, Part 1910, and the Construction Standards, Part 1926.
