Most inexpensive pumps are centrifical not positive displacement type.  A
centrifical pump can be throttled very easily, since they put out a pretty low
pressure, and are not harmed by the output being throttled or blocked.  For a
very low flow, try some of the valves they sell at pet stores for aquariums for
the air lines, or if you are dealing with a large flow, a ball valve from Lowes
or Home Depot would do the trick.
