Verderflex Peristaltic Pumps

Based in Vleuten in the Netherlands, the Verder Group consists of a number of technical production and trading companies all over the world.

Verder provides production and sales of pumps and pumping systems, mixers, milling and sieving equipment, storage, feeding, conveying, classifying, granulating, odour reduction equipment and industrial tooling.

These activities can be broken down into three key fields.

• Liquids Handling - posisitve displacement pumps for all fields of industry
• Laboratory Equipment - sample preperation equipment and particle size analysis
• Process Handling - equipment, tools, turn-key projects, industrial odour control

Peristaltic pumps work using the process of peristalsis to pump products through a hose, in the same way that blood, food and oxygen are pumped around the body.

The hose sits around a rotor which, when turning, compresses a segment of the hose almost flat.

This compression is released as the rotor moves around the hose with the hose reinforcements causing it to spring back to its round shape, thus creating a partial vacuum refilling the hose.

This compression creates a seal and, as the rotor turns, any product on the discharge side of the rotor is propelled forward and displaced from the pump.

Combining this suction and discharge action results in a self-priming positive displacement pump.

The Verderflex pump stands apart from its competitors: it is a flexible, reliable peristaltic pump of robust construction capable of handling difficult products in arduous conditions.

Verderflex pumps are renowned for providing top-quality solutions to an array of problems within process industries around the world.

The hose is the most important feature of any peristaltic pump and therefore Verderflex has ensured its hose is tough, long-lasting and capable of withstanding corrosive and abrasive applications. The Verderflex hose can also be used in other peristaltic pumps on the market, for more information click on the hose page.

One of the main differences between Verderflex and its key competitors is that a Verderflex pump allows the customer to choose a local gearbox supplier thereby maximising local flexibility and reducing potential servicing problems.

Another difference is that Verderflex comes with close- and long-coupled design options, meaning the pump is flexible enough to adapt to different applications. Due to the often dangerous nature of the products pumped by Verderflex pumps, the range had been designed to provide maximum safety to the workforce and environment. The pumps’ hose connection is disaster-proof – unlike other peristaltic pumps, the Verderflex range has a completely sealed hose connection avoiding leakage and therefore eliminating any danger.

Verderflex pumps are incredibly accurate at dosing: they offer a repeatability accuracy of ±1% without any slip. They also have a vacuum capability of 95% or a 9.5m/31’ lift of water.
