Combine sturdiness, simplicity of use and high efficiency:
Sahara Mk2 is the only automatic bilge pump that eliminates air-locks. Its engineered performance forces air bubbles trapped in the hose and underside of the pump out of the pipework, so that the pump will not run dry and burn out. This breakthrough technology makes Sahara Mk2 the most reliable automatic bilge pump in freshwater and saltwater applications.
