    What Types of Pumps Are Used in the Mining Industry?

    When mining ore to extract useful minerals from the earth, pump systems are depended on to make sure that day-to-day operation runs efficiently. There are numerous types of pumps that are utilized in the mining industry.

  • Avoiding Vibration in Vertical Pumps

    Avoiding Vibration in Vertical Pumps

    Vertically suspended pump types VS1, VS2, VS3, VS6 and VS7 are typically flexible structures above the mounting plate. Focusing on the above-base structure of a vertical pump and the frequency of the first bending mode, it may coincide with running speed(s) or other forced vibration frequencies.

    Pump System Fundamentals New Industry Professionals Should Know

    Typically, pump manufacturers use water to obtain the values for their pump performance curves, even if the intended service of the pump is for a fluid with properties that are different from water. But what happens when the fluidā€™s viscosity significantly deviates from water? This is where engineers need to adjust the pump performance curves…

    How Do Modifications to Seal Faces Improve Their Operation?

    Pumps are at the heart of most industrial processes and the second most common machine in the world (after the electric motor). Because they are so common, pumps are often overlooked as a potential source of improved productivity or a cause of excess costs if not operated properly.

  • How to Detect Cavitation

    How to Detect Cavitation

    A common problem in pumping systems is pump cavitation. Pump cavitation causes a number of issues including excess noise, vibration and energy usage, not to mention serious damage to the pump itself.

    NPSH: Know the Consequences of Disregarding Facts

    Process pumps are machines that take liquid from a suction condition to a discharge condition. In its typical form, there usually is a shaft-mounted impeller (or impellers) that, together, make up a rotor. Impellers impart velocity to the fluid as it passes from pump suction to pump discharge. Whereas in the pump casingā€™s internal passageways,…

    Valves’ Effect on Flow Rate & Water Hammer

    Not all valves are well suited for controlling system flow rate. Overall, the performance and characteristics of each valve will affect the magnitude of any transients developed by valve closures and openings. It is important to consider rate of flow change versus valve position and control the closure rate of the valve such that the…

  • Total Head for Pumps & Systems

    Total Head for Pumps & Systems

    The term ā€œtotal headā€ (H) is used to describe the energy in pumping systems and is how manufacturers represent the performance of their pumps as a function of flow rate.

  • What is Cavitation?

    What is Cavitation?

    Centrifugal pumps are sometimes used in environments where the pumped product contains suspended solids. While some pumps are specifically designed for solid handling or slurry applications, normalĀ centrifugal pumpsĀ do not contain features to prevent performance degradation from the impact of solids.
