Pumps handling fluids that can form flammable gases utilize what type of system?

Pumps handling fluids that can form flammable gases utilize a quenching or smothering system as a preventative measure against fire hazards. These systems are designed to eliminate or reduce the risks associated with flammable vapors that may be generated during the pumping process. By introducing a non-flammable substance or strategically managing the environment around the fluid, these systems help create a safe operational zone. This can be critical in industries where volatile organic compounds or other flammable materials are handled.

A pressure relief system, while important for managing excessive pressure in a system, does not specifically address the handling of flammable gases in the same way a quenching or smothering system does. Similarly, a vacuum sealing system focuses more on preventing contamination and maintaining product integrity rather than mitigating flammable gas risks. Lastly, a filtered air system is aimed at providing clean air and does not inherently address the issues of flammable gas formation. Thus, the use of a quenching or smothering system is crucial for safety when dealing with pumps that could potentially handle flammable gases.
