Product Description: Viking Compact Hand Bilge Pump This rugged yet sleekly designed, single-chamber diaphragm pump provides first-rate performance and is a snap to install. It can be fitted in minutes from one side of the bulkhead with just four screws, self-sealing against the surface with a durable, watertight gasket. With the pump house recessed behind the bulkhead, only the handle is visible from the cabin or cockpit. The Viking Compact's inlet and outlet ports can be swiveled 360° and are delivered in two sizes with every pump. Naturally the Viking Compact has connectors fitted as standard, literally making those connections a snap. Polypropylene body with ABS cover, nitrile rubber valves and diaphragm.
