Winch 55 Self Tailing EVO Lewmar – Grey

The pack, comprising a grey water tank and a Gulper Whale pump, is designed for the on-board water system of sailing yachts or catamarans, including those from brands such as Nautitech Catamarans and many others.

The Whale grey water tank

With a capacity of 8 litres, this tank stores waste water from showers, sinks, washbasins and air conditioning units on board your boat. Made from polyethylene, neoprene and polycarbonate, it is ideal for installation in the hold of your pleasure boat. Installed on a 12 / 24 V network, the tank comes with a range of connection diameters (see technical specifications). The Whale tank is fitted with a float that detects the water level and triggers the pump to discharge the grey water.

The Gulper 320 Whale pump

The Gulper 320 Whale pump is installed directly on the tank. Installed on a 12 V mains supply, it is activated when the grey water tank is full to discharge the water through the boat’s hull. It can be rotated 360° and has connections for Ø19 or 25 mm hoses.
