VERDERFLEX PUMPS USED FOR DOSING PROCESS REAGENTS, COAGULANTS AND FLOCCULANTS 

Verderflex Pumps Used For Dosing Process Reagents, Coagulants And Flocculants

Posted on 6 August 2013
Global Pumps provides the Verderflex peristaltic hose pumps, which have many applications in the mining processes.

Here are some of the applications of Verderflex in the mining operations:

The content of the minerals present in the mineral ores vary continuously and the recovery systems accommodate these variations. The Verderflex pumps perform the crucial function of varying the dosing rates consistently to optimize the usage of chemicals and maintain appropriate output from the plant. The peristaltic hose pumps are an ideal complement to the plant SCADA systems because they have provide a linear flow and have excellent repeatability.

Verderflex peristaltic hose pumps are used for the pumping of process reagents like cyanides and acids, which are highly corrosive in nature. The hose present in the peristaltic pumps is exceedingly resistive to these chemicals and is the only part of the pump that comes in contact with the dangerous chemicals. No other parts of the pump are exposed to these caustic chemicals.

Other chemicals, like lime, which are used for controlling the pH of the solutions, are highly abrasive in nature and they can cause continuous clogging of traditional dosing pumps such as diaphragm pumps, that can result in extensive downtime and maintenance issues. Verderflex peristaltic pumps supplied by Global Pumps have exceptional records of dosing lime into process and waste fluids and many of these pumps are used for bulk dosing to remediate post-mining waste and effluents.

In many cases the reagents mixed at the mine or processing plant form imperfectly dissolved solutions, leading to the generation of slurries, liquids that have a percentage of solids. These can be harmful to ordinary pumps, but not to the Verderflex pumps.

Verderflex peristaltic hose pumps have a seal-free design that eliminates the possibility of leakage of potentially harmful chemicals into the workplace or the environment.

For some highly aggressive solutions like Copper Sulphate, the pumps can be nickel plated to maximise pump’s corrosion resistance and increase its operational life.

Studies on Verderflex peristaltic hose pumps reveal that they have gentle pumping action, resulting in a lower shear rate of the chemical particles compared to the other traditional pumps, thus maintaining a constant flocculent size. This helps to increase efficiency, requiring the use of fewer chemicals.

Global Pumps, a major provider for peristaltic hose pumps, is an Australian based company founded in 1977 to fulfil the need for a versatile and service oriented specialist supplier, sourcing pumps and pumping systems from around the globe. Global Pumps delivers complete solutions for customers located throughout Australia and New Zealand, incorporating a technical service division that performs onsite installations and servicing.
