Whale’s Supersub Smart Electric Bilge Pump Impresses Practical Boat Owner Magazine

The narrow, low profile, automatic and compact bilge pump range fits deep down in small or awkward bilge spaces where other pumps won't fit.

Recently featured in an article in Practical Boat Owner magazine entitled, ‘Whale beat the bilge pump blues’, the high performance pump impressed with its low current draw.

Technical writer, Emrhys Barrell said, “Whale, who have been at the forefront of bilge pump technology for many years, claim that their Supersub Smart pumps have very low standby drain…

We tested our pump in a tray of water, and measured the current drain as the water level rose up the sensor. The maximum we recorded on standby was an amazingly low 0.51mA. Quite remarkable, as this means that even if you left it connected to your battery for three months, it would draw just 1Ah…

As far as performance is concerned, the Supersub has always come out at or near the top of our comparative tests, both for maximum output and efficiency in terms of output per amp.”
