Peristaltic pump puts paid to problems with sludge transfer
Teys Australia, one of the largest meat processors and exporters in Australia, was looking for a dependable solution for its DAF tank sludge and scum transfer at its plant in Beenleigh, Queensland. The company had used submersible pumps and double diaphragm pumps in the past, but with limited success. A Hydro Innovations pump specialist recommended the use of a Ragazzini peristaltic (hose) pump for the application. Ragazzini hose pumps are positive displacement pumps using a set of rollers to compress an elastomeric tube that pushes the fluid contained within it. This means that no mechanical moving parts are in contact with the fluid being pumped, and there are no valves or seals to ever replace. And because the pumps use rollers and not “shoes”, the casing does not need to be filled with an expensive lubricating fluid. Teys needed to transfer up to 10 cubic metres an hour of the sludge, so Hydro Innovations recommended the Ragazzini MS3 peristaltic pump with fully cast casing, cast iron rotor and castiron rollers.
The abattoir has been so happy with the installation, it has since rolled this new technology out to other branches around the country.
The pump needed only to run at the slow speed of 26 rpm to meet the duty, so the pump is expected to have a very long service life. It is also fitted as standard with a leak detector that instantly detects a damaged hose. The leak detector stops the pump and sends a warning signal. Pumps are mounted on stainless steel base
frames and are supplied with 316SS ports. The pump was duly ordered and installed. An operator at the plant commented that “it was easy to install and works very well, with little maintenance. A great feature is not having to fill the roller section with glycol, and the quiet operation of the pump,” he said.
Ragazzini pumps are available in sizes ranging from 10mm ports up to 150mm, with flows from 0.2 litres per hour up to 180 cubic metres per hour, with pressures to 15 bar. Various pump hose materials allow pumps to move abrasive fluids, corrosive fluids, fats, oils, along with FDA approved hoses for foods and pharmaceutical products.
