Product Description
Verderflex Dura 55 Peristaltic Pump
The Verderflex Dura 55 Peristaltic Pump provides precise fluid handling for demanding dosing, metering and transfer applications. Moreover, its positive-displacement hose technology keeps the pumped liquid fully contained inside the hose.
As a result, the fluid does not contact mechanical seals, valves or moving metal components. This design helps preserve product purity while reducing leakage and contamination risks.
The Dura 55 delivers flow rates up to 15,300 litres per hour and pressures up to 16 bar. Therefore, it suits challenging UAE chemical, water-treatment, mining and industrial processes.
High-Pressure Peristaltic Pumping
The Dura 55 uses a twin-lobe, single-rotor pumping mechanism. During operation, the rotor compresses the reinforced hose and pushes a controlled liquid volume towards the discharge connection.
After compression, the hose returns to its original shape. Consequently, it creates suction and draws more liquid into the pump.
The seal-free flow path also allows the pump to run dry without damaging a mechanical seal. In addition, the pump provides strong self-priming performance.
Key Benefits of the Verderflex Dura 55

- Maximum operating temperature up to 90°C
- Maximum operating speed of 80 rpm
- Self-priming performance
- Dry-running capability
- Reversible pumping direction
- Gentle, low-shear fluid handling
- Accurate dosing and metering
- Only the hose contacts the liquid
- No mechanical seals in the fluid path
- Secondary containment around the hose
- Fast and straightforward hose replacement
- Handles abrasive and viscous liquids
- Multiple hose-material options
- ATEX, FDA and EC 1935/2004 options
Together, these features support reliable pumping with fewer fluid-contact components.
Flow and Pressure Performance
The Verderflex Dura 55 provides the following operating capabilities:
- Maximum flow: 15,300 litres per hour
- Maximum discharge pressure: 16 bar
- Maximum suction lift: 9.5 metres water column
- Maximum fluid temperature: 90°C
- Maximum speed: 80 rpm
- Maximum compressible particle size: 13.75 mm
- Maximum smooth incompressible particle size: Approximately 5.5 mm
However, actual output depends on speed, hose material, discharge pressure and fluid properties. Therefore, users should confirm the complete duty conditions before selecting the drive and hose.
Fluid Purity and Containment
The pumped fluid remains inside the reinforced hose throughout operation. Therefore, it does not contact the rotor, casing or gearbox.
This arrangement helps preserve fluid purity in sensitive processes. Moreover, it reduces cross-contamination when users select the correct hose material.
The surrounding pump casing also provides secondary containment. Consequently, it helps control fluid if the hose fails.
Abrasive and Solids-Laden Fluids
The open hose flow path allows the Dura 55 to handle abrasive slurries, suspended solids and viscous products.
Unlike conventional pumps, it does not use narrow internal valve passages. As a result, solids can pass through the hose with less risk of blockage.
The reversible operating direction can also help clear some obstructions. However, users should still confirm the maximum particle size and fluid characteristics before selection.
Compact Industrial Construction
The Verderflex Dura range uses a close-coupled design that requires less floor space than many traditional hose pumps.
Therefore, the Dura 55 suits compact dosing skids, treatment rooms and industrial process areas. Verder states that the Dura range can require up to 70% less floor space than conventional peristaltic pumps.
A quick-fit port flange design also simplifies hose installation. Consequently, maintenance teams can replace the main wearing component more efficiently.
Hose and Connection Options
Available hose materials include:
- Natural rubber
- NBR
- Food-grade NBR
- EPDM
- CSM
Therefore, users can select the hose according to chemical compatibility, abrasion resistance and temperature requirements.
However, the correct hose depends on the actual liquid concentration and operating conditions. Consequently, users should complete a chemical-compatibility review before ordering.
