Why Pump Head and Flow Rate Calculations Matter Every industrial pump must be sized correctly. If the pump is too small, it cannot deliver the flow or pressure your process needs. If the pump is too big, you waste money on power, equipment, and maintenance. The right way to pick a pump is to first…
Why Is My Centrifugal Pump Not Developing Pressure? It is one of the most common calls we get at Rinku Engineers: “My centrifugal pump is not developing pressure. What is wrong?” The operator starts the pump, the motor runs fine, but the discharge gauge reads much lower than it should. The plant slows down, and…
What Is NPSH in a Centrifugal Pump? If you work with centrifugal pumps, you have heard the word NPSH. It stands for Net Positive Suction Head. In simple words, NPSH is the amount of pressure you have at the pump suction, measured in meters of liquid, above the vapor pressure of the liquid being pumped.…
What Is Centrifugal Pump Cavitation? Centrifugal pump cavitation is one of the most common reasons pumps fail early in the field. It happens when the pressure inside the pump drops too low, the liquid turns into small vapor bubbles, and those bubbles collapse with great force as they move into higher pressure zones. Each tiny…
