You don't need a big pump regardless of the size of the
spindle motor. I use a small Little Giant pump that's
often sold for fountains, hydroponics, etc. I get the
best version they make and it's still inexpensive. Good
brands include Superior and the upper end versions of
Little Giant. Here are a couple of possible examples.

There are also the blue Little Giant pumps that are not
fully immersed.
Here's a pic of one style. You'd have to make sure it
delivers enough pressure to keep the spindle cooled, but
this is similar to what I have for flood coolant.
