The Johnson Pump Marine Viking Universal is a heavy-duty, hand-powered bilge pump designed for dependable performance when power is unavailable. This self-priming diaphragm pump can be mounted vertically or horizontally, with flexible installation options behind walls, through deck or below bulkheads using the optional Through Deck kit. Its adaptable design allows the hose connections and pump housing to be rotated for optimal positioning, while large 38 mm valves make it suitable not only for bilge pumping but also for pumping toilet waste. Built for marine reliability, it meets ISO 15083 bilge pumping system requirements and delivers up to 60 l/min at 45 strokes per minute.
