Transcript for the video:
This is the Ragazzini peristaltic pump model MS3.
It has a roller on bearing design, so does not need the casing to be full of lubricant.
Having no moving parts in contact with the pumped media and only the hose in contact with the fluid, maintaining the pump is simple and inexpensive.
They can operate on suction lifts up to 8 metres and pressures to 15 bar.
It is seen here pumping a thick piggery sludge, including plenty of solids, at a farm in southern New South Wales.
