Verderflex Dura 65

Verderflex Dura 65 Hose Pump

The proven Verderflex Dura hose pump series has grown. The new Verderflex Dura 65 hose pump replaces the popular Verderflex VF65.

Thanks to the optimization of the rotor, rotor shoe and the sliding surface of the hose, the new Verderflex Dura 65 achieves the highest flow rate on the pump market at this size. With a maximum flow rate of 33,000 liters/hour, it exceeds the performance of the previous VF 65 by 20%. Since the rotor requires fewer revolutions for this performance, the hose has less occlusions and therefore achieves a 20% longer hose service life.

The pump offers a sealless and valveless, proportional flow rate. Therefore this pump is ideal for transfer and for dosing. The robust hose can be changed on site. View hose change video. With new filling nozzle and service access port this is simplified further.

The smaller pump sizes of the Verderflex Dura are also available with an integrated frequency converter including potentiometer and installed hose breakage monitoring: The iDura. It is available for the Dura 5 – Dura 35. The iDura series can be controlled via 4-20 mA, Modbus® RTU, CANopen or Profibus via the inverter.

 

Max Capacity: 33 m3 /h

Max Pressure: 16 bar

Temperature Range: Max 100 °C

Features

  • Class leading Continuous Flowrate of 22m3/hr .
  • Greater utilisation of hose so greater swept volume (Higher flow/lower revolutions = longer hose life).
  • The same reliable design of the Verderflex hose providing an optimum hose life.
  • Filler Nozzle/Access port – Can change the hose without removing the front cover.
  • Self-priming/ Dry Running/Sealless Peristaltic Technology.

For the Owner – Increased the utilised length of the hose so that the unit now has a class leading swept volume and can achieve a maximum continuous flow rate of 22m3/hr. This puts our DURA 65 with a flow rate that matches existing pumps in the market place which are designated as ‘80’ size. So cost per flowrate is better value for money.

For the User – Verderflex have made some modifications which ensure that servicing is more about ease, and reduced time rather than mess and complexity. There is now a fill nozzle for the lubricant and a service access port on the front cover.

To make it safer, Verderflex have fitted a lifting point on the front cover, and added a valve and hose tail at the lubricant drain port so it will not go all over the floor when emptying.

There is an option for a level indicator, and also max/min fluid sensors for the lubricant bath – so it can be connected up and remotely monitored. (This can also support hose failure monitoring).
