Verderflex has launched the Dura 55 pump, which is designed to deliver 20 per cent more flow, increasing the Dura Hose pump range’s flow range from less than one litre per hour to 15.3m³ per hour at pressures of up to 16 bar. According to the company, the Dura 55 outperforms its competitors in both continuous- and intermittent-duty applications. 

The Verderflex Dura 55 solves 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. This makes the Verderflex Dura 55 suitable for applications including biogas production, brewing, fly ash recirculation, chemical manufacturing, industrial processing, mining and water treatment.

The Verderflex Dura 55 has a patent-pending port flange that totally encloses the hose. This flange 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 and PVDF inserts for aggressive chemical duty options.

Its heavy-duty design guards against blockages and chokes with its advanced stalled rotor protection technology, including visible slippage indicators. This 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. 

Reinforcing the heavy-duty design is the pump’s casing and rotor, made from high-tensile-strength SG iron, which is unlike the lower-specification GG iron used by many competing products.

Key features and benefits

  • The Verderflex Dura 55 meets growing market demands for a pump that can reduce lifecycle costs, maximise plant uptime and incorporate special design features for arduous heavy-duty applications. 
  • It delivers more flow per revolution, increasing hose life by decreasing the number of revolutions to pump a given volume for longer hose life and expanded maintenance intervals. 
  • It is said to have the optimum design to maximise strength and longevity.
  • The quarter-turn lock system halves hose change times to maximise plant uptime.
  • The system’s heavy-duty design guards against blockages and chokes with its advanced stalled rotor protection technology, including visible slippage indicators.
  • The Dura 55 eliminates potential rotor, rotor shoe or gearbox damage when the pumped liquid settles out or a line chokes. This enhances the system’s suitability for pumping sludge, slurries and all kinds of vicious and waste liquids.
  • The Verderflex Dura 55 pump’s rotor shoes are fully supported, eliminating potential stress weak points.
