With its heavy machinery and accident-prone work conditions, the industrial world is not for the faint-hearted. However, there are some industry types, such as oil refining, petrochemical or nuclear, that are more dangerous than others for those involved. The reason for this is the nature of the processes, materials, and environments, which carries an increased risk of explosion.
In these environments even a small spark or excessive heat can turn into a fire within seconds. For instance, in a chemical manufacturing facility flammable vapors are present in the air due to the production process. A pump used at the facility creates friction and heat, which may give rise to a spark. The combination of the spark and flammable atmosphere may lead to an explosion, posing a significant risk to both personnel and the facility.
When you deal with explosive hazards on a daily basis, you need specialized and reliable equipment that can handle the pressure. Learn more about our explosion-proof pumps, the ultimate solution for settings vulnerable to ignition and explosion.
Welch’s explosion-proof pumps are specially designed to prevent internal and external explosions by enclosing the parts that could ignite the material being transported or found in the surrounding area. The key benefits of Welch’s pumps for hazardous environments include:
Discover Welch’s comprehensive range of explosion-proof pumps designed to meet the diverse needs of various applications, such as vacuum ovens, freeze dryers, and distillation.
Our pumps are suitable for various industries that work with highly combustible materials, such as oil refining, petrochemical, utility, power generation, nuclear, environmental monitoring, and more.
When a pump is described as explosion-proof, what it actually means is that the pump’s motor is equipped with special safety features. The explosion-proof motor design is not a guarantee that the pump is immune to internal or external explosion. Instead it makes sure that internal motor incidents don’t lead to more dangerous situations in the surrounding environment.
If you take a closer look at the motor enclosure in Welch’s pumps, you will find an UL listing identification plate. It is proof that our pumps have been tested and certified for compliance with strict safety standards.
Welch’s explosion-proof vacuum pumps stand out as a reliable choice for Zone 2 environments.
Areas classified as Zone 2 are characterized by the occasional presence of flammable gasses and vapors in quantities that may pose a risk of ignition. To mitigate this risk, equipment and devices used in such areas, including pumps, must meet stringent standards for explosion protection.
In Welch’s explosion-proof pumps, the motor and electronic components are placed in a sealed enclosure to prevent the entry of the flammable substances inside and the release of sparks or excessive heat outside.
