Save time and energy pumping up your raft. Carlson pumps are made to last, using heavy-duty PVC and a foam O-ring seal that does not require grease. Fitted with a 7' non-kink hose. 24" high. Ten year guarantee.
There's a screw that secures the top cap. Shouldn't take a lot of servicing.

There is no reason to open it for cleaning or service, It is maintenance free. I have used one for over 15 years and it takes the abuse with no problem. As far as I am concerned this is the best pump for topping off rafts and inflating small boats.
