Not too easy to advise you when all you say is that you have 25 (or so)
fields of equipment like pumps and shakers, but...
from what you have said, I would be looking at
table :equip
equip_uid
equip_type_uid
equip_info
table: type
type_uid type_name
You add a type (say 1,"Pump")
and you add an equip (say 1,1,"Sludge")
from that, you know that the equip record is about a pump ( because its
equip_type_uid = 1 and you can look that up in the type table and find
that type_uid of 1 has a description of "Pump"
Your problem with multiple fields is that if you ever need to search,
you have 25 fields to look in, not one. This way, it is easy to search
(SELECT * FROM equip WHERE equip_info LIKE '%sludge%') and the type
table makes it easy to create dropdown boxes, search by category (no
misspelt "pmup") and you will probably save space, and if you rename
"Pump" to "Liquid Transfer Engines" you only have to do it in one place
(likewise, if you have a Spanish site, you only need another table
"type_es" with 1,Bombe" and all the equipment has Spanish categories.
