Hubby Sandberg developed the complete pump system. There was no pump system available for kayaks that worked satisfactory, and after comprehensive research and testing we can claim that this is the best pump available internationally.
Each pump consists of two inflations (one under each foot) two inlet and two outlet valves, tubing, suction and outlet grommets, stainless steel screws, bolt and nut and instruction sheet. The pumps are mounted on two very sturdy nylon brackets that also support the valves. The inflations for the K1 measures 120mm.
The non-return valves are nylon injected, with a neoprene ball attached to a high quality stainless steel spring. The valves do not block as they are self cleaning in use.
The pump is lightweight and the valves are unconditionally guaranteed. Once installed correctly these are the most efficient kayak pumps on the market as they work continuously with your paddle motion, therefore keeping the kayak dry at all times.
The K1 pump is capable of pumping 4.5 litres of water per minute.
