The proven Verderflex Dura hose pump series from industrial equipment supplier Verder Pumps, has grown.

The new Verderflex Dura 65 hose pump replaces the popular Verderflex VF65, boasting 20% more flow and 20% longer hose life.

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 ℓ/h, it exceeds the performance of the previous VF65 by 20%. Additionally, since the rotor requires fewer revolutions for this performance, the hose has less occlusions and therefore achieves a 20% longer hose service life.

“The new Verderflex Dura 65 is much more than just a facelift to replace the Verderflex VF65. Our research and development team placed significant focus not only on the technical standpoint, but also what would make life easier, for both the owner and the user, when developing this pump,” says Verder Pumps South Africa MD Darryl Macdougall.

The pump offers a seal-less and valveless proportional flow rate. Incorporating the technical advances from the rest of the DURA range and increasing the used length of the hose so that the unit has a class leading swept volume enables the pump to achieve a maximum continuous flow rate of 22 m3/hr. This puts the DURA 65 with a flow rate that matches existing pumps in the market, which are designated as ‘80’ size, making the cost per flowrate with the Dura 65 better value for money. Additionally, the robust hose can be changed on site.

Verder has also made some modifications which ensure that servicing is more about ease, and reduced time rather than mess and complexity. There is now a filling nozzle for the lubricant, and a service access port on the front cover.

To make the pump safer, a lifting point has been fitted on the front cover and a valve and hose tail have been added at the lubricant drain port so it will not spill all over the floor when emptying. There is an option for a level indicator, and max/min fluid sensors for the lubricant bath – so it can be connected and remotely monitored.

This can also support hose failure monitoring.

Key features of the Dura 65 hose pump are class leading continuous flowrate of 22 m3/hr, greater use of hose, so greater swept volume (higher flow or lower revolutions equals longer hose life), the same reliable design of the Verderflex hose providing an optimum hose life, and a filler nozzle/access port allowing the user to change the hose without removing the front cover.
