Queensland abattoir installs Ragazzini hose pump

A Queensland abattoir was seeking a solution for its DAF tank sludge and scum transfer, having previously used submersible pumps and double diaphragm pumps with limited success. A pump specialist from Hydro Innovations recommended the Ragazzini peristaltic (hose) pump for the application.

Ragazzini hose pumps are positive displacement pumps that use a set of rollers to compress an elastomeric tube that pushes the fluid contained within it. No mechanical moving parts are in contact with the fluid being pumped and there are no valves or seals to ever replace. The casing of the pumps does not need to be filled with lubricating fluid because they use rollers and not ‘shoes’.

The abattoir needed to transfer up to 10 m³/h of the sludge, so Hydro Innovations recommended the Ragazzini Ms3 peristaltic pump with fully cast casting, cast iron rotor and cast iron rollers.

To meet the duty, the pump needed to run at the slow speed of 26 rpm to meet the duty, so it 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, stops the pump and sends a warning signal. Pumps are mounted on stainless steel base frames and are supplied with 316SS ports.

An operator at the plant said the pump was easy to install and works well with little maintenance.

Since installing the pump, the abattoir has rolled it out to other branches around the country.

Ragazzini pumps are available in sizes ranging from 10 mm ports up to 150 mm, with flows from 0.2 L/h up to 180 m³/h, 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.
