Dec. 5, 2014 -- Following its Dura 45 hose pump, Verderflex, a manufacturer of peristaltic hose and tube pumps, has announced an expansion to its Dura 55 range. This pump is designed to deliver over 20-percent more flow, increasing the Dura Hose pump family's flow range from <1 l/hr to 15.3 m³/hr at pressures up to 16 bar.

The Dura 55 meets growing market demands for a pump that can reduce lifecycle costs, maximize plant uptime and incorporate special design features for arduous heavy-duty applications. Further, it solves pumping problems associated with dry-running liquid streams, shear-sensitive polymers, high-viscosity sludge and pastes, variable-speed dosing, and abrasive solids in suspension and off-gassing fluids

This makes the Verderflex Dura 55 ideal for use in a wide variety of applications including biogas production, brewing, fly-ash recirculation, chemical manufacturing, industrial processing, mining, and water treatment.

Low Lifecycle Costs

The Verderflex Dura 55 delivers more flow per revolution. This significantly 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 users' lifecycle costs is the Verderflex hose. Like all Verderflex hoses, the Dura 55 hose has the optimum design to maximize strength and longevity.

Maximize Plant Uptime

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

Heavy-Duty Design

The Verderflex Dura 55's heavy-duty design guards against blockages and chokes with its 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 key design feature enhances the 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 unlike the lower specification GG iron used by other products. The Verderflex Dura 55 pump's rotor shoes are fully supported, eliminating potential stress weak points.
