Are the outlet and inlet pipes of the pump the same size? Why?

Are the inlet and outlet pipes of the pump the same size? I came across this phenomenon at work recently, and I’m very confused and puzzled. Recently we acquired an independent wash pump; nothing special about it – it has a motor and a pump body, with a head of 50 meters. Its purpose is to clean the cooler. As far as I remember, the inlet diameter seems to be reduced (probably to prevent cavitation), but we used pipes for connection, with an inlet diameter of 100 mm. Considering pressure issues, the outlet pipe had a diameter of 50 mm.
The inlet pipe is thick while the outlet pipe is thin; the technician told me a method to determine the inlet and outlet, to prevent cavitation
The large inlet diameter is used to reduce flow velocity, minimize resistance, and prevent cavitation； The outlet is small; choosing a slightly higher flow rate appropriately is intended to reduce costs.

Some have large imports and small exports, some have equal import and export volumes – it depends on the specific requirements
Generally, the pump inlet is larger than the pump outlet; there are also ones with the same diameter
The import value is one level higher than the export value; if they are the same, the pump is prone to cavitation
