The K4 is K-Pump's latest addition to their line of expedition quality pumps. Born out of repeated special orders from military and commercial customers seeking a ultra-compact, high-volume dual stage pump. The K4 sheds nearly one pound of weight and six inches of length compared to our popular K-40 pump. This is perfect for a top off pump for larger rafts and RIBs, or as an all around pump for smaller craft like yacht tenders, pontoons, kayaks, etc. The high pressure stage can comfortably reach up to 9 psi. The K-4, like all K-Pump models will work on most all valves including the "H-R" (Halkey-Roberts), Leafield and Boston valves.
