We order most of our NDK kayaks with the hand pump recess. It is a great safety feature and takes the guess work out as to where to carry your pump. So that means we need to carry the pumps that fit the molding. This is the second generation of the NDK pump recess molding.
So we have the durable and repairable Kajak Sport hand pumps. Stainless steel shaft 12" in Length, and have a bungee tether cord. These pumps move a good amount of water.
