The peristaltic pumps's operation is obtained through a "flow pressure" which acts on a flexible hose; this pressure is exercised by some rollers, assembled on a support, which turn parallel to the axis. The slow rotary motion of the roller support is trasmitted by a two or three steps gearmotor at 35,86 or 114 rpm, equipped with a MEC -56 motor 0,09Kw with 1450 rpm, continuos service.
The mechanical parts are machined on a lathe to obtain a high precision and individually calibrated during assembly and subsequent testing to distribute an uniform pressure on th hose ensuring a perfect self-priming and a longer life of the hose.
The NORTON hoses are extruded with high precision, in order to prevent the occlusion and the low volumetric yield.
Easy to clean and maintain. Max suction height: about 8 meters with a Ø 12.7 mm hose, and about 6 meters with a 15.9 mm hose. Max. pressure allowed for the hose: 1.4 Kg/cm2.
Max temperature: 60 º C.
These pumps are able to pump viscous liquids with particles in suspension, without suffering any damage. They hold the liquid in their passage, preventing the backflow of the liquid and the "siphon" effect. Possibility to working dry and reverse the rotation direction. the 35rpm speed is suitable for high viscous fluids (polyelectrolite), or liquid that you do not want to alterate.
