Caustic (Sodium Hydroxide)

sodium hydroxide plant

Positive displacement pumps are ideal for transferring caustic liquids like sodium hydroxide due to their ability to handle high-viscosity fluids and provide a consistent and controlled flow rate. These pumps work by trapping a fixed amount of fluid and forcing it through the pump system, which ensures that the flow remains steady even under varying pressures. This is particularly beneficial for caustic liquids as it reduces the risk of fluid damage or hazardous spills that could occur with more turbulent flow patterns.


Additionally, these pumps are capable of operating at low speeds and shear rates, minimizing the risk of chemical reactions or changes in the properties of the liquid due to agitation or heat. This makes them suitable for handling sensitive or reactive chemicals safely and efficiently.

Viking Pump patent for mag drive technology
Viking Pump invented, patented and manufactured the very first sealless mag drive rotary positive displacement (PD) pumps in the world, and developed several series over time for different applications, including the first generation 825, 895 and 855 ™ internal gear pumps. Of these first generation mag drive pumps, all had different footprints from their dynamically-sealed cousins with...
