Insects have hearts, although nothing like our familiar muscular mammalian hearts. These consist of a narrow tube along the insect’s back that pumps blood (or hemolymph) towards their head. This circulates fluid in an open system with no veins or arteries. The smallest insect is said to be the fairy fly which is a type of wasp that’s less than 0.2 millimeters long. You’d need a microscope to see its heart...
The smallest pump part
Even pumps need XXS format because these masterpieces in their brilliance of our engineering consist of many different and sometimes very small elements. And it is precisely these smallest components that matter, whether the pumps can work perfectly for a lifetime or not. We searched for the smallest part of a pump. And we have found it in a standard pump from our ACP series. The pump component in XXS format is an impeller and weighs about 1900 grams. It has a length of 125 millimeters and consists mainly of stainless steel.
