Verderflex Dura Series Peristaltic Hose Pump

The Verderflex Dura sets the industry standard for handling high-viscosity, abrasive, and shear-sensitive fluids. Featuring a compact close-coupled design that reduces floor space by up to 70%, it offers a suction lift of up to 9.5 meters, self-priming dosing accuracy within ±1%, and indefinite dry-running capability.

Overview

The Verderflex Dura is an innovative, compact peristaltic hose pump engineered for demanding industrial dosing and transfer applications. Its unique close-coupled layout saves up to 70% in floor space compared to conventional peristaltic pumps while extending hose life and operational reliability.

Key Features & Advantages

  • Compact Footprint: Occupies up to 70% less floor space thanks to its advanced close-coupled design.
  • Precise Dosing: High metering accuracy within ±1% across varying operating pressures.
  • Safe Dry-Running: Can run dry indefinitely without damaging internal components.
  • High Suction Lift: Superior self-priming performance with up to 9.5 m wc suction lift.
  • Air Gap Protection: Prevents process fluid from contaminating the motor gearbox in case of hose failure.
  • Smooth Operation: The rotor is centrally positioned over bearings to minimize radial forces, reduce power consumption, and extend pump life.
  • Fast & Simple Maintenance: Quick hose changes keep downtime and operating costs to a minimum.

Typical Applications

  • High-viscosity sludge, slurry, and paste transfer
  • Shear-sensitive fluid dosing
  • Abrasive and corrosive chemical metering
  • Water and wastewater treatment processing
