This Whale Gulper Grouper Pump provides efficient evacuation of waste from spaces such as the fishbox, livewell, and baitwell. Its proven design and technology are superior to macerator pumps, so there’s no filter to clog, no impeller to jam up, and no motor burn-out. Instead, there’s just reliable clean-out. The non-choke valves in the pump head ensure reliable, clog-free pumping, and it is done efficiently with a low power draw. This is a rugged, durable pump, and it can be used in multiple wells, which further enhances its value and productivity. Its multi-directional head with 360-degree head rotation capabilities means it can be used in a variety of wells. This 12-volt DC, 10-amp pump uses 1 inch or 1 ½ inch hose connections and has a 5. 8 gallons per minute peak flow rate. The pump body features aluminum and glass-filled nylon construction, and the fasteners are corrosion-resistant stainless steel and brass. Whale designs and manufactures reliable marine water system products which are easy to install and use; providing boaters with hot and cold water, waste management and durable bilge pumps for peace of mind.
