3.1 701RA Pumphead description
The 701 ATEX pumpheads use the peristaltic principle by employing 4 occluding rollers assembled as a
rotor, which occludes a specially designed tube and provides fluid flow by positive displacement as it
rotates.
The pumphead is largely of coated metal construction with metal shafts for the occluding rollers. The
occluding rollers are driven by a gear within the pumphead and are of nylon construction. The rotation
of the occluding rollers is allowed using roller bearings. Materials of construction are detailed in this
manual.
The pumphead is designed to be direct mounted or close coupled onto a suitable motor gearbox using
the instructionsdetailed in this manual.
