Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not California. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial pumps in California”
2“Who supplies chemical-resistant centrifugal process pumps in California”
3“I need a California pump supplier for a continuous-duty wastewater treatment line, who should I talk to”
4“Top industrial pumps suppliers in California for plant maintenance and reliability buyers”
5“Which California industrial pump suppliers can handle high-viscosity fluids at high temperature”
6“List 20 industrial pumps companies in California with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
