Are you selecting the right pump materials for acid mine water?

Packo MCP pumps:

Knowing that acid mine water is highly corrosive and abrasive, acid mine water applications require pumps that are robust and designed to handle corrosive fluids. The pumps must also be easy to maintain and relatively low in cost to operate. For example, 316L stainless steel and duplex stainless steel centrifugal pumps perform better in many ways, due to the unique yet simple design and corrosion resistance of the stainless steel.

Stainless steel contains a significant proportion of chromium (at least 15%), which forms a thin, inert oxide layer on the surface. Unlike iron oxide, this binds strongly to the metal surface and therefore protects the underlying metal in environments that would be highly corrosive for cast iron or carbon steel. Other elements such as nickel, manganese and molybdenum may also be added to stainless steel to further enhance corrosion resistance. Under the right conditions, the protective oxide layer is self-repairing if it is scratched or damaged. This contributes to an improved pump efficiency, lower energy cost and less wear over time, making such pumps easy and cost effective to maintain, while supporting plant-process optimisation. This makes them 100% fit-for-purpose for the application. Read on to learn more about why our Packo MCP 3 Pumps are perfectly suited to the pumping of acid mine water.
