The surface temperature of the pump depends upon the temperature of the fluid that is being pumped. The chart below lists different fluid temperatures and the corresponding pump surface temperatures, which determine the Temperature Class when used in a hazardous area. Maximum Surface Temperature Maxium Allowable Fluid Temperature Temperature Class Surface Temperature 80°C (176°F) 80°C (176°F) 85°C (185°F) www.sera-web.com...
Halogenated hydrocarbon solvents can cause explosion when used with aluminum components in a closed (pressurized) system. sera airPUMPs with standard materials of construction contain aluminum components and will be affected by halogenated hydrocarbon solvents.

If pump is used with materials that tend to solidify or settle, the pump should be flushed after each use to prevent damage. CAUTION Use only genuine sera replacement parts to assure compatibility and longest service life. CAUTION Check the temperature limits for all wetted components when choosing pump materials. See table below.
