Why Verderflex Pumps are so Popular in the Mining Industry

Verderflex peristaltic pumps are the “gold standard” in the mining industry when it comes to pumping slurries. There are two reasons for this. First, a peristaltic pump is the best choice for pumping slurry. Second, Verderflex makes the best peristaltic pumps in the world. It’s easy to see why Verderflex has become the “go to” choice for mining companies for pumping slurries.

Here are some reasons why Verderflex peristaltic pumps will always be the best choice for pumping mining slurries.

Verderflex Peristaltic Pumps

They Use Less Water

A peristaltic pump, also called a hose pump, can move slurries with as much as 80% solid content. A standard centrifugal slurry pump begins to lose efficiency if the solid content is more than 30%. But what do these numbers mean to a mining corporation?

Every time a centrifugal slurry pump is replaced with a peristaltic hose pump in an operation that is processing 75 tonnes of ore per hour with slurry that is 65% solids, it saves more than 1,100 million liters of water per year because of the rise in efficiency. The peristaltic pump requires 25% less water to operate than the slurry pump.

They Use Less Power

Using the above example of a plant that processes 75 tonnes of ore per hour, a Verderflex VF-135 hose pump needs 35 kW of power to complete the task. Meanwhile, the slurry pump would use slightly more than 70 kW. This not only saves more than 50% of your power, it also lowers the demand and requirements for power in your mine.

If you are building a new mine, it will cost less for the infrastructure to provide power for your operation because it won’t have to be so large.

They Reduce Overall Plant Size and Increase Efficiency

Because a peristaltic pump can handle up to 80% solids, it reduces the need for post thickening filter stages. This helps decrease the initial cost and running costs of a mining operation. It also means the plant doesn’t have to be as large.

They Have Less Environmental Impact

If a mine is using a cyanide-based leaching technique, it can contaminate the land and water surrounding the plant. When cavity pumps are used for dosing, the seals are always at risk for losing their integrity. Peristaltic pumps don’t have seals, reducing the risk of contamination greatly.

In addition, they use less power, reducing carbon footprint.

They Minimise Damage

Because the pumping action in a peristaltic pump is the most gentle of other options, cell structures in bio-oxidation reaction techniques sustain less damage. When separating gold from sulphide ores, it improves process yields while lowering cyanide usage.

They Reduce Reagent Usage and Treatment Costs of Acid Mine Drainage

Because of the low-shear, gentle action of a peristaltic pump, particle size is maintained and it isn’t necessary to use as high a quantity of process reagents. Other pumps such as cavity pumps or screw pumps use high-shearing action which increases reagent usage and operating costs.

This often creates more residual reagent, increasing the cost of waste remediation. It can also create more groundwater pollution and other environmental damage.

They Reduce Maintenance Costs

Due to the acidic content in many slurries, a traditional slurry pump has a much shorter life than a peristaltic pump. Peristaltic pumps use less expensive materials and have longer service lives.

They Reduce Downtime

Verderflex peristaltic pumps reduce downtime because a rubber hose is the only material that comes in contact with the slurry. Not only do the hoses last longer, but they can be replaced more quickly. This adds up to less downtime for replacement on two levels. They last longer and are replaced faster.

Less Special Parts

Metal impellers on other pumps often have to be made with exotic materials. Verderflex peristaltic pumps are made with a series of standard elastomers that can withstand chemicals used for processing.

One of the best is Verderflex. We are appointed Western Australian distributors for their peristaltic pumps. Verderflex has proven, over and over again, for close to 50 years, to be the best, most reliable and most durable peristaltic pumps in the world.

How Peristaltic Pumps Work

Peristaltic pumps imitate the motion of a human or animal swallowing food or water. Fluid is in a tube that closes off and pushes the fluids or solids further along the pump. A peristaltic pump does it by using a rotating roller or “shoe” that moves along one side of a hose, compressing it and moving the fluid or solids in the direction that the shoe is moving.

When the shoe totally compresses the tube, it seals off the intake end from the discharge and efficiently moves every bit of fluid or solid in the tube. Nothing is left behind. As the shoe moves down the hose, the part that was compressed is let go, expands and creates a vacuum, drawing in more fluid.

The substance being pumped never comes into contact with anything but the inside of the tube. Peristaltic pumps are used often for dosing applications. Verderflex pumps with tubes handle up to two bars of pressure, while those with hoses can handle up to 16 bars of pressure.

The high pressure hose is built for endurance and strength. It has an outer layer and between two and six reinforcement layers. Reinforced tubing is more efficient for creating suction and allows for higher working pressures.

Peristaltic Pumps for Food and Beverage Applications

Peristaltic pumps are a mainstay in the food and beverage industry in Perth and for good reason. They are good for dosing and metering flavourings, liquid ingredients and chemicals in commercial food production. They can transfer solids that are highly viscous from location to location.

They also work well for transporting food slurries and food waste. Peristaltic pumps are used in potato processing plants to ground potato skins and other wastes. This slurry is 70% solid but is easily moved by the action of a peristaltic pump.

Peristaltic Pumps for Food and Beverage Applications

Peristaltic pumps use positive displacement to move fluids through a tube. Imagine that you are trying to drink a milkshake through a straw, but the fluid is too thick. So, you squeeze two fingers together at one end of the straw and move them toward you in a motion that pushes the milkshake through the straw for you to enjoy.

This is the action produced by a peristaltic pump, but instead of fingers, a peristaltic pump uses rollers. Because the pumping action all happens outside the tube, there is no possibility of contamination. In the food and beverage industry, where sanitation is mandatory, this is important.

Peristaltic pumps have even been used to move live fish. The fish are in water and the peristaltic action causes a wave that washes the fish along with it. Wine manufacturers use peristaltic pump to move the seeds, peels and stems, collectively known as “cap,” to the pressing stations.


Peristaltic pumps are usually cleaned by running a cleaning solution through it backwards. This can also clean upstream piping. Since the only part of a peristaltic pump that ever comes in contact with whatever it is pumping is the hose and the fittings on either side, there is virtually no risk of cross contamination and it can be cleaned in place.

Verderflex Peristaltic Pumps Repair Mining Damage to Water

Peristaltic pumps are important to the mining industry. In South Africa, they are playing a major role in rebalancing the pH of water in and around the mines. South Africa is a different situation than WA, but it does serve as a warning for what can happen here in WA if the mining industry isn’t careful.

MiningIn South Africa, there hasn’t traditionally been a lot of regulation in the mining industry. Consequently, years and years of unregulated activity has caused the acidity of water in South African mines to increase by unprecedented levels. The situation has escalated to a point where it could have a serious effect on the population around the mines.

So, what does South Africa’s mining industry have to do with us here in Perth? Their situation should serve as a cautionary tale for our own mining industry here in WA. Our mining boom is only a few years old, and our safety regulations are much better here, but it is never too early to start looking out for our future.

For the mining industry, it means that they can use South Africa’s situation to peek into the future and help them to eliminate any potential problems before they become big enough to cost them serious money. Acid Mine Drainage (AMD) is a serious problem in South Africa, and it can affect crops and quality of water, resulting in less production and a loss of farming jobs.

Dosing Lime with Peristaltic Pumps

South Africa’s CSIR, which stands for Council for Scientific and Industrial Research, has developed a process they call the Alkali-Barium-Calcium (ABC) Process. First, lime and/or CaS are pre-treated. Then, sulphate is removed using Barium treatment. Then, the sludge is processed.

Verderflex peristaltic pumps are used for the treatment. They move the fluids by using positive displacement inside of a flexible hose, pushed by an external “shoe” in a circular motion. With this kind of pumping, the high viscosity of sludge never causes the pump to clog, and the fluid never touches any of the moving parts.

Processing with a peristaltic pump is reliable, energy-efficient, and eliminates the chance of cross-contamination.

How Verderflex Pumps Help Make Wine

Verderflex has a reputation for making the best peristaltic pumps in the industry. That is why we distribute Verderflex pumps. We only import the best pumps from around the world because we know that downtime can cost you money. We know that you need the most efficient, reliable pumps for all industrial applications.

Verderflex pumps are used for a variety of applications: mining, wastewater, printing, pharmaceuticals, chemicals, automotive and the food and beverage industry. Peristaltic pumps are so named because they mimic the action of your digestive tract when you swallow; that process is called “peristalsis.”

Verderflex Pumps Help Make Wine

Peristaltic pumps are great for uses where sanitation is mandatory and contamination cannot be tolerated. The fluid being moved through the hose is never touched by any of the pump mechanism, which squeezes the hose at one end and moves towards the exit, pushing the fluid along as it goes.

Peristaltic Pumps Used in Filter Press for Wine

In modern winemaking operations, the juice from grapes is fermented in giant stainless steel vats that are opened at the top. Yeast is added, which converts the grape sugars into alcohol. When the alcohol is produced, the yeast is then filtered out, leaving pure liquid wine.

The way the yeast is removed is by the addition of diatomaceous earth (DE), which forms a slurry and attracts the yeast to cluster with the DE. A Verderflex peristaltic pump is then used to pump the slurry into the filter press. The press system contains a VF-25 hose pump which is fed through a 32 mm suction line. The line is fitted through a converter and connects to 25 mm tubing.

When the chambers are filled with the slurry of wine, yeast and DE, the pressure is approximately 10 bar. This is the maximum pressure, so the Verderflex pump is fitted with a sensor that stops the Verderflex pump if the pressure reaches 10 bar.
