You can put a ball valve on the outlet side of the pump to adjust the flow, or to be able to more finely adjust the flow, a gate valve. Note though that you will be increasing the back pressure by cutting down the flow. I have used these pumps for aquarium applications, but never for hot wort. I do know that as the pressure increases its maximum temperature tolerance decreases, but at mash temperatures I suspect that you would be fine.
