Mining slurry pumps are subjected to harsh conditions. In fact, no industry puts its pumps through such harsh conditions as the mining industry. When mining site managers are under pressure to meet their output targets, the last thing they want is for their pumps to fail especially when it is difficult to prevent pump failure. Read on as we talk about some of the most common causes of mining pump failure and some of the best ways to avoid them.

The right pump design prevents clogging

One of the most frequent and common causes of mine pump failure is clogging. With time, suspended solids will clump together and clog the mining pump. The key to avoiding this problem is in selecting a pump that is designed to meet your unique needs. No matter the mix of solids to liquids you are pumping, there are pumps that are specifically designed to handle it. By selecting the right pump, you can easily eliminate and reduce problems down the line.

Reduce the effects of corrosion

Mine pumps deal with a wide range of punishing environments and liquids. From phase drilling fluid to emulsified fluid, your mining pump will have to withstand harsh materials. You can minimise this effect of corrosion by choosing a pump designed for the task and built using high-quality materials. Choosing slurry pumps constructed with the right metallurgy is the best way to boost their reliability and increase their lifespan.

A lot of construction materials such as super-duplex stainless steel and some polymers offer great durability and protection in harsh environments. Although expensive, these pumps offer great performance even after years of contact with corrosive liquids that would damage pumps made from standard materials.

Another effective way to prevent pump failure due to corrosion is by using anodes. Anodes are made of metal with a lower electrode potential such as zinc, aluminium and magnesium. Most of the corrosion will occur on these soft materials and not on the important elements within the pump. It is important to monitor the anodes and replace them when they get worn out over time. Sometimes, it is difficult to avoid corrosion. In some applications, corrosion can happen to even the hardest metals. However, using anodes and choosing the right mining pump will help.

Do not knock it

Protecting your mining pump is essential to avoid severe damage from accidents or mine traffic. Location is very important. You should place your mining pump in an area that is away from larger and heavier equipment. Choosing the right pump location can mean the difference between doing your job effectively and stopping everything for a pump replacement.

Mining pumps also get thirsty

If you run mining slurry pumps then you probably know that overheating is something that can happen to your pump, especially during prolonged operation. Your pump might get dry and overheat and this will lead to damage or complete failure. To prevent this, it is important to ensure your system is running correctly and monitor the water levels and ensure regular pump maintenance checks are performed.
