A pump casing is an outer shell of a pump meant to seal off internal components from the outside atmosphere while maintaining desired fluid pressure and preventing leakage. There are different casing constructions depending on the pump type, and each serves a distinct function.
With so many choices available for industrial pumps, the selection process often comes down to carefully evaluating the needs of the industry and choosing a pump that will be efficient and reliable in a specific application.
The case is no different when selecting sliding vane and rotary gear pumps. While both are types of positive displacement pumps, there are nuances that make one or the other better suited for a particular application.
Efficiency is an essential factor that influences pump selection. Wire-to-water efficiency is often a critical parameter when selecting a pump, especially when the pump needs to operate in an industrial environment. In large-scale industrial applications, even a difference of 10% in efficiency can significantly impact overall operating costs in a year.
In industrial engineering, friction can be helpful in some areas while it can severely affect performance in others. In pumps, friction serves the latter purpose. When two surfaces slide across each other, there acts a resistive force called friction. This resistive force slows down the movement between the parts and expends energy in the form of heat or sound.
Metering pumps or dosing pumps are used to add small and precise amounts of fluid into another fluid stream.
Metering pumps are primarily seen in industries where the precision in addition of chemicals or substances to a larger quantity matters (for example, in producing medicine). Let’s find out more about how these metering pumps work and their major applications.
The standard pump performance curve is plotted with reference to water as a fluid medium. However, in many cases, pumps are used for fluids other than water, and the characteristics of those fluids can have significant effects on the pump’s performance. Viscosity and Specific Gravity are two essential variables in fluids that can impact the performance of any pump.
Pump bearings are components that enable rotation within pumps under load. Therefore, a good bearing is essential for the pump to function correctly. However, 'pump bearing' is a broad term, encompassing different types of bearings that we use today. In addition, pump bearings are also classified based on the kind of load they can support.
Canned motors and magnetic drive pumps fall into the category of seal-less pumps. Seal-less pumps replace the conventional mechanical seal with a static containment shell. The advantage of such a system is that it ensures no fluid leakage. Hence, seal-less motors are the preferred choice when you need to pump fluids that should not leak out in the atmosphere.
Pump impeller balancing is not a term that you’d frequently hear when dealing with pump repairs. However, when it does pop up, it usually means a tedious job of restoring the efficiency of a pump to its original performance. Let’s find out what pump impeller balancing is, why it’s needed and how to perform pump impeller balancing.
Wastewater from industries is a major hazard to the environment. According to a UN water report, 80% of all wastewater flows back to water resources without being treated. This is one of the reasons why many countries mandate industries to treat wastewater sufficiently before it's released.
