Explosion Proof Pumps

What is an explosion proof pump?

A pump designed to prevent the internal environment within the pump from becoming ignited and exploding. They are required in environments where explosion is a possibility, such as in sewage treatment plants or in refineries. Because there are so many different types of pumping applications where explosion resistance is imperative, they can take numerous forms.

Explosion proofs pumps may be heavy-duty industrial positive displacement pumps such as piston pumps, diaphragm pumps, or plunger pumps. In some cases they may also be centrifugal pumps. The main criteria for this type of pump is that the motor and all of the wiring and motor controls are designed to eliminate the possibility of a spark which could cause an explosion.

Where are they used?

They are used in any pumping application where there is a significant risk of explosion because of the type of fluid being pumped. Obviously, this isn't a problem where water is the primary fluid being pumped. But these pumps are especially useful in the pumping of inflammable materials, particularly oil-based fluids, natural gases, adhesives, many types of chemicals, and many types of hazardous materials. This makes them useful in mining, natural gas extraction, and many types of hydrocarbon processing plants.

Other related Pump Types include: industrial pump, chemical pump, process pump, sludge pump.
