K-Pump: A Compact Hand Pump for River Inflatables
The K-Pump is a compact hand pump designed for topping off rafts, catarafts, inflatable kayaks, and other river inflatables without a loose external hose to manage. Choose the K-Pump 100 for more air per stroke and faster inflation, or the K-Pump Mini when packed size and weight matter most.
Both models are designed for one-person operation, fit a wide range of common inflatable-boat valves with the included adapters, float if dropped in the water, and are made in the USA.

Features & Valve Compatibility
No External Hose
The pump connects directly at the nozzle end, eliminating a separate inflation hose that can kink, pull loose, or take up additional space in your repair and inflation kit.
Common Inflatable-Boat Valves
The nozzle and included adapters are designed to work with many common inflatable-boat valves, including Leafield, Halkey-Roberts, Summit, Boston, and AD-2 styles.
Built-In Cache Cap
The Cache Cap provides a small waterproof storage space inside the pump shaft. It gives you a convenient place to keep pump adapters, keys, or other small items such as compact first-aid or field-repair essentials.
Compact Enough to Carry
K-Pumps are designed to take up relatively little room in a boat or gear load, making them useful as a primary pump for smaller inflatables or as a top-off and backup pump for larger boats.
They Float
Both the K-Pump 100 and K-Pump Mini are designed to float if they end up in the water.
K-Pump 100 vs. K-Pump Mini
K-Pump 100
Choose the K-Pump 100 when you want more air per stroke and faster inflation while keeping the pump compact enough for river use and storage.
- Weight: 2 lbs
- Diameter: 3"
- Length: 22"
K-Pump Mini
Choose the Mini when saving space and weight is more important than maximizing air volume per stroke.
- Weight: 1 lb
- Diameter: 3"
- Length: 15"
Is the K-Pump Right for Me?
The K-Pump is a strong choice if you:
- Need a compact manual top-off pump
- Want a pump that can stay in your river gear
- Don't want to manage a separate inflation hose
- Need broad valve compatibility
- Want a manual backup that doesn't require electricity
- Inflate river tubes or inflatable kayaks
For a large raft that starts completely deflated, a higher-volume barrel pump or electric blower can reduce inflation time. A K-Pump can still be useful for topping off and as a compact manual backup.

Frequently Asked Questions
What is a K-Pump best used for?
It is especially useful as a compact top-off pump for rafts and catarafts and as an inflation pump for smaller inflatables such as inflatable kayaks and river tubes.
Which model should I choose?
Choose the K-Pump 100 for more air per stroke and faster inflation. Choose the Mini when minimum size and weight are the priority.
Can it fully inflate an inflatable kayak?
Yes. K-Pump lists inflatable kayaks and river tubes among the products these pumps can fully inflate.
Can I use it on a full-size raft?

No external hose is required. The pump connects at the nozzle end.
What valves does it fit?
The nozzle and included adapters are listed for Leafield, Halkey-Roberts, Summit, Boston, and AD-2 style valves.
What is the Cache Cap?
It is a small waterproof storage compartment inside the pump shaft for adapters and other small items.
Will the K-Pump float?
Yes. Both models are designed to float.
Where is it made?
