New Dura 55 Hose Pump

The company says the Verderflex Dura 55 is the class leader for this size of peristaltic pump and can outperform its competitors in both continuous and intermittent duty applications. The addition of the Verderflex Dura 55 expands the Dura range’s flow rates from <1 l/h to 15.3m³/h at pressures to 16 bar.  

The Dura 55 meets market demand for a pump that can reduce life cycle costs, maximise plant uptime and incorporate special design features for arduous heavy duty applications. It is said to be capable of solving pumping problems associated with dry running liquid streams, shear sensitive polymers, high viscosity sludge and pastes, variable speed dosing, abrasive solids in suspension and off-gassing fluids, making it suitable for use in a wide variety of applications including; biogas production, brewing, fly ash recirculation, chemical manufacturing, industrial processing, mining and water treatment.

The Verderflex Dura 55 delivers more flow per revolution. This increases hose life by decreasing the number of revolutions to pump a given volume for longer hose life and expanded maintenance intervals. A key attribute behind lowering user’s life cycle costs is the Verderflex hose. The Dura 55 hose is designed to maximise strength and longevity.

The Verderflex Dura 55 has a special, patent pending port flange that totally encloses the hose. This design also includes a quarter turn lock system, halving hose change times to maximise plant uptime. Normally, supplied in 316 Stainless Steel, this flange design also has optional PP & PVDF inserts for aggressive chemical duty options. 

The pump's heavy duty design guards against blockages and chokes and features advanced stalled rotor protection technology, including visible slippage indicators. This advance eliminates potential rotor, rotor shoe or gearbox damage when the pumped liquid settles out or a line chokes, reducing both maintenance costs and production downtime. This feature enhances the Verderflex Dura 55’s suitability for pumping sludge, slurries and all kinds of vicious and waste liquids.

Reinforcing the heavy duty design is the pump’s casing and rotor, made from high tensile strength SG iron. The Verderflex Dura 55 pump’s rotor shoes are fully supported, eliminating potential stress weak points.
