The Gulper 320 is a high capacity shower drain, bilge and waste water management system. The market leading Whale Gulper is the original specifically designed filter-free waste pump. The self-priming diaphragm pump can handle a variety of debris and run dry without damage. There is no impeller to clog or burn and non-choke valves built into the pump means there is no filter to block or clean, a strainer is also included to prevent large debris from entering the pump. This means the pumps are easy to maintain and installation is simple with a mutli-directional head allowing the pump to be mounted in the most convenient position. The Gulper 320 is self-priming up to 3m (10ft) and has a high flow rate of up to 19 ltrs (5 US gals) per minute.
