The short answer is yes, a trash pump will do what you want. We use them to some degree on our department if the need arises. They're not going to make much pressure, but they will move and dump a pile of water on a fire with a decent stream.
Restrictions aren't good for any pump. The problem is simply in a lack of circulation. No circulation, and in fairly short order they will boil the water in their pump housings, and then things get cooked... so you don't restrict trash pumps or fire pumps for any more than a minute or two.
One thing you might watch for, if you want a small fire pump, is something like a Wajax fire/forestry pump. We use the older Mark III's, which are decent little pumps. They only move mabey a hundred GPM on a 1.5" line, but that's plenty fo most small grass fires. These are a pressure pump....
Their only downfall is that they can be a good deal more contankerous than a Honda trash pump.... but they will do work that the trash pump won't do.
There's alos old fire pumps out there like Hale and Thibault/Pierreville portables, but they can run you a bunch of money..... Choices, choices. Again, the trash pump will work on a limited basis.
