Drainman Bilge Pump

● The Drainman (Länsman) is a fully automatic bilge pump, powered by the tug on the moorings created when the boat moves with the wind and waves. The Drainman’s capacity is enormous; powered entirely by the movement of the mooring line, it can pump up to 2,500 litres of water per day (550 UK gallons or 660 US gallons per day). The Drainman is made from rugged materials with a tensile strength of up to 10,000 Newton. The Drainman is a reliable companion when you have grown tired of marine covers or of constant bailing.

 

 

1. The Drainman features two loops, one on either side. One loop is connected to a mooring line by means of a shackle or a snap-hook, the line is then attached to the mooring point, for instance on a jetty. Mooring springs should not be used.

2. The loop on the other side is connected to the boat, using a shackle or a snap-hook, such that the Drainman is attached between the boat and the mooring point. Make sure that the hose and label are facing up when installing, and that the pump is kept above the surface of the water.

3. Place the sieve of the suction hose in the lowest point of the boat (the keelson), where it can easily drain the water. For increased stability, a weight may be placed at the end of the suction sieve loop.
