Attwood's Tsunami Mk2 Bilge Pump is the only manual bilge pump that eliminates air locks thanks to a patented X-air impeller that ejects trapped air in the pump and pipework, preventing the pump from running dry and burning out.

Tsunami Mk2 is one of the easiest manual bilge pumps to install and service, owing to its external mounting feet and integrated outlet that reduces time and effort.

So what is Air-Lock?
Air-Lock (also known as vapour lock) is a restriction of, or complete stoppage of liquid flow cause dby vapour trapped in a high point of a liquid-filled pipe system.

Key Features:

90 degree rotatable elbow outlet enables you to install the pump anywhere in a full 360 degree orientation.
Exterior mounting feet eliminate the need to remove the basket.
Industry leading motor and shaft seals provide better protection against harmful corrosion that, in another instance, could cause failure.
No pipe or hose removal is required, reducing the time that it takes to replace the cartridge.
Patented X-Air Impeller that prevents air locking so that the pump will not run dry and burn out.
Single hand pump cartridge release is convenient when trying to access a pump located in a hard-to-reach area of the boat's hull.
Tricuspid check valve helps prevent the water from back flowing through the pump.
