Peristaltic Pump Solves Tough Application Problems

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, abra-sive solids in suspension and off-gassing fluids. According to the company, the Verderflex Dura 45 delivers 25% more flow per revolution than equivalent mod-els, 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 pro-duction downtime.
