K-Pump 40 HP Hand PumpThe K Pump K 40 High Pressure hand pump is the "little brother" of the K 400. Same great two stage design, with both high volume and high pressure modes. More compact and easy to stow where space is limited. The K 40 is the ideal choice for smaller boats IKs, kickboats, etc. Only 24" in length, 4" in diameter and 3 pounds in weight, it stows compactly. The primary stage delivers approx. 1. 2 gallons of air per stroke, filling your tubes quickly. When
