The award winning Whale SS1224 SuperSub Smart 1100 automatic submersible bilge pump eliminates the need for a separate float switch to activate the pump. Once power is supplied to the bilge pump, starting and stopping is completely automatic. The Whale SuperSub automatic bilge pump features a narrow low profile design, ideal for confined spaces. The Whale SuperSub submersible bilge pump can be fitted into compartments where height restriction is an issue. It is easy and simple to install, easy to clean and leaves the bilge almost dry! The integrated solid state switch ensures power consumption is minimised and that there are no moving parts. The SuperSub bilge pump should only be used in the bilges of leisure craft, if used as a sole or primary bilge pump it is only suitable for vessels up to 24 metres (78.8ft). The Whale automatic bilge pump comes complete with a non-return valve. The Whale SuperSub Smart bilge pump conforms to ISO 8849 and ISO 15083 standards.
