Can run dry indefinitely and provides suction when dry. Also very suitable for viscous liquids like lubricating oil.
Is used to pump out open excavations and in the foodstuffs and chemicals industries.
Can also be used as a submersible pump.
The ATEX version is ideal for use on tankers or where there is an explosion risk.
