The obvious ones - flowrate, generated pressure, suction pressure, fluid characteristics in as much detail as possible. Plus type of driver, power supply data if electric motor, and any constraints like preferred type, pump speed and material.

I would add that any Standards that might pertain due to the type of installation such as American Petroleum Institute (API-610) for refinery applications, chemical pump applications might have ANSI, Boiler Feed Water might come under ASTM etc.

There are often certain design requirements such as casing material (no cast iron in hydrocarbon service in refineries or must use chrome-steel for high temperature) and also based on temperature, center-line mounting of casings versus foot mounted.
