Ragazzini Peristaltic Pump for sludge and slurry

Click2Contact

The Ragazzini Peristaltic Pump is suitable for sludge and slurry.

With no mechanical parts in contact with the fluid and no valves or seals to wear, fail or clog, the pumps are easy to maintain.

The pumps use a peristaltic mechanism, where rotating rollers compress a flexible, resilient tube, thus creating a wave-like motion that transfers liquids through the system. Pumped media includes viscous fluids, corrosive fluids, abrasive fluids or fluids with solid particles.

Because they use rollers, the pumps do not require the casing to be filled with lubricating fluid.

Pumps can also be run in reverse to fill or empty, and can run dry without damage.

This versatile pump finds its application across diverse sectors — from food and beverage processing to pharmaceuticals, and from mining to wastewater treatment. It has a gentle pumping action, enabling the handling of shear-sensitive fluids, but it is also heavily constructed for handling solids-laden liquids like sludge and slurry.

The pump’s simple design reduces downtime, requiring minimal maintenance and spare parts. Hoses are easy to change because there is no messy fluid in the pump casing, and no other parts are required for regular maintenance.

Capable of handling abrasive and viscous materials, the pumps are also able to handle large solid particles (to almost half the diameter of the hose).

Using rollers instead of shoes to compress the tubular element not only reduces heat and wear but also reduces the power needed to move the rotor.

The slow-moving nature of the pumps is designed to deliver a precise amount of fluid transferred with each revolution, minimising waste and ensuring consistent quality.

Some hoses available with these pumps have FDA approval and are capable of being cleaned with steam or with hot water and cleaning agents.
