The Aquadesign manual bilge pump is designed to provide rapid clearance of water that enters a boat, canoe, kayak or other water craft. Its piston, with a length of 35cm and diameter of 5cm, can clear 700ml of water with each hand pump action, amounting to approximately 30 litres per minute. Fitted with comfortable EVA foam and an easy-to-use handle, this bilge pump can sustain a steady water clearance rate in an emergency. Its 90cm-long water discharge pipe (optional) can be used to shift water clearance to drain standing water in hard-to-reach places.
