Verderflex’s Dura 45 peristaltic pump solves a number of pumping problems for medium flow applications up to 12m3/h, according to the company. These could include dry-running liquid streams, shear-sensitive polymers, high-viscosity sludge and pastes, variable-speed dosing, abrasive solids in suspension and off-gassing fluids.

According to the company, the Verderflex Dura 45 delivers 25% more flow per revolution than equivalent models, requiring 300 less revolutions to pump 2,000 liters and outperforming its competition at pressures up to 16 bar. Notable features include an innovative quarter-turn-to-lock system for fast hose changes, and solid cast stainless steel flanges.  Normally supplied in 316-grade stainless steel, its patent-pending flange design has integral PP and PVDF inserts for aggressive chemical-duty options. The Verderflex Dura 45 also offers stalled rotor protection, eliminating potential rotor, rotor shoe or gearbox damage when the pumped liquid settles out or a line chokes, reducing both maintenance costs and production downtime.
