We have a background note on Hazardous Area Surveillance that may help explain what 'Class 1, Zone 2' means. It actually is the least-stringent rating in the rating spectrum, but it still is quite expensive! (Perhaps 10X - 15X the price of non-rated gear.)
So with that in mind, what options do you have mounting cameras outside the hazardous area? Can you mount the cameras clear of the pumps on poles and optimize lensing and resolution that way?
It might be expensive to spec a camera mounted farther from the target, but it might ultimately be far cheaper than mounting one rated for a hazardous area.
Pelco offers a series of housings that meet or exceed Class 1 Zone 2 requirements, but the housing doesn't address cabling/conduit/power supplies that often need to be certified also.

Careful. The Pelco housings are certified. Place a camera in one and the system is not certified. Spectrum Camera (Link) builds certified systems. We've used them on a few projects and everything has gone very well. Do consider the extra conduit costs!
