Please note: We highly recommend the use of a pressure gauge with the K-Pump K40 pump to avoid damage to your inflatable. The Kwik Check gauge is accurate and easy to use.

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.

    Pump 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.

    K-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.

FREQUENTLY ASKED QUESTIONS

What is the difference between the K-40 and K-400 pumps?

The K-40 and K-400 are K-Pump’s largest diameter pumps. The difference is the K-40 is 25% shorter than the K-400. The K-40 is a very popular choice because it is easy to pack, and lighter weight, yet still produces over 70% of the volume of the K-400. The K-40, like all K-Pump models, will work on most valves including the Halkey-Roberts, Leafield and Boston valves.
