| Pump difficult liquids | Precision dosing | Can Dry Run |
| Solids in suspension, thick viscous liquids, aggressive chemical solutions pumped with ease | Ideal for abrasive slurries, flocculants or offgassing liquids | No damage if supply line runs dry |
Applications
The varied chemical industry has many pumping challenges - abrasive liquids, aggressive chemicals, minimal ancillaries, gentle pumping actions, accurate process addituions, crystallisation …all problems solved by Verderflex peristaltic pumps
Chemical Dosing Pumps
Verderflex chemical dosing pumps are ideal for delivering chemicals at a controlled rate. Peristaltic dosing pumps contain the liquid within the tube or the hose, eliminating risk of contamination. This makes a peristaltic pump the perfect choice in water treatment applications such as phosphate removal, pH control as well as for making energy from organic waste.
Chamber filter press
A chamber filter press is a machine for separating sludges, slurry or fluids containing solids into solid ‘cake’ and liquid ‘filtrate’ parts. A filter press machine is used extensively in the treatment of waste and by-products in the food, chemical, mining and pharmaceutical industries. The cake and filtrate can be recycled back into the process, sold off for further processing or disposed of more economically.
Phosphorous removal Metering Skid System
3 Vantage 5000 pumps are installed on a single “drop-in” skid system to treat fly ash run off water to neutralise high phosphorus residual levels.The first pump precisely doses CaCl2 raising the leachate’s pH level for optimal flocculation by the other two pumps. The flocculants dosing pumps gently to remove the residual phosphorous, avoid costly over-dosing and minimising treatment costs. Each pump is easily controlled using simple 4 to 20mA signals with real time performance feedback and status alarms and the “drop-in” skid minimises on-site commissioning time.
Spraying insecticides
Sanz Hnos were pleased to use the Verderflex M500 OEM pump in their insecticide and fungicide spray systems.The compact and light pump easily fitted into the Sanz Hnos backpack design and the low battery drain from the dc motor made the M500 the perfect choice for a portable pump unit.
Pumps for the chemical industry
Verderflex peristaltic pumps are manufactured in the EU within ISO 9001, ISO 14001 and ISO 45001 accredited facilities.
Verderflex® Dura
The Verderflex Dura is a true 2nd generation pump : the first real advance in hose pump technology since the high pressure hose. It combines a close coupled pump's compactness with the traditional long coupled pump's benefits and gains from a total re-design rather than adapting an original concept.
| Max flow | 33000 l/h |
| Max pressure | 16 bar |
Verderflex® Vantage 5000
The Verderflex Vantage 5000 family is the next generation in precision dosing and dispensing pumps. They combinine accuracy at discharge pressures up to 7 bar with an intuitive, touch screen user interface, a 30 program onboard memory, real time clock and a USB data backup port. Remote control signal options include 0-10V, 4 to 20mA, Modbus® & Profibus® with optional multiple opto isolated volt free inputs & outputs allowing the Vantage 5000 to form the heart of automated, process critical metering and transfer systems for abrasive, off-gassing, chemcially aggressive, shear sensitive or fragile chemicals, nutrients and pH control systems.
| Max flow | 6600 ml/min |
| Max pressure | 7 bar |
Verderflex® Rollit
Lubricant-free peristaltic hose pumps. The Verderflex Rollit is a family of lubricant-free, easy to maintain, low to medium pressure hose pumps. Rollits are available as 2 bar, 4 bar or 2 bar Hygienic versions with single or twin head styles.
| Max flow | 24500 l/h |
| Max pressure | 4 bar |
Verderflex® VF
The original Verderflex peristaltic hose pump series is now solely focussed on high flow applications and includes the widely used VF125, the world's largest high pressure hose pump.
