Verderflex Dura Series Peristaltic Hose Pump

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
