Cornell self-priming pumps replaced electrical submersibles in a tomato processing plant. The pumps are used in the trash wash phase, where tomatoes are cleaned prior to being processed. This wastewater stream carries leaves, grit, dirt; stems, and other materials.
The electric submersibles were unreliable, often failing, and backing up the wastewater into the facility. Given the need to expeditiously process the tomatoes in the short growing season, the delays were very costly to the plant.
The Cornell 6-inch self-primers worked flawlessly.
