Product Tip - Pumps do require easy-to-do maintenance over time. Periodically apply lithium grease to the pump shaft. This keeps the O-ring gasket lubricated, helping you pump easier and faster. Always make sure fittings and adaptors are snug and free of dirt and other debris. The O-ring can be replaced if worn or damaged.

- RBRussell B.Verified BuyerRated 5 out of 5 stars7 years agoPump review
Well I have not use this yet, pumping up my raft this week to go fishing. I sure it will be everything I expected thou, did a lot of research on pumps and this got the best marks of all the different pumps on the market. All the testimonials I read and product reviews steered me to K-Pumps, so I am sure this is going to work perfect for me.
- JJohnVerified BuyerRated 5 out of 5 stars7 years agoGreat Pump
It's a lightweight, compact pump that works great. My family likes to tube and this is perfect for a trip to the river.
- CCmacmaineRated 4 out of 5 stars13 years agoK-Pump K40 Raft & Kayak Pump
For an inflatable kayak, this is the way to go. I was predisposed to get an electric pump, but after discussing with a rep chose to buy only the hand pump. It was the right choice. It fills the IK in a few non-fatiguing minutes. Since you need a top-off pump anyway, save the unnecessary expense of the motor.
