Cambiaste el sello mecánico el viernes. El lunes vuelve a gotear. En el taller te preguntan si revisaste la camisa del eje, el runout, los rodamientos y el flush antes de montar el sello nuevo. Si no lo hiciste, el sello nuevo simplemente repitió la falla.

En esta guía de campo abordamos cómo cambiar un sello mecánico de una bomba centrífuga: qué revisar antes de tocar un perno, cómo inspeccionar para no repetir la fuga, qué errores pueden hacer fallar un sello nuevo en horas y cómo hacer un arranque...

Welcome to our comprehensive guide to the different types of pumps in the industry. Pumps play a crucial role in various industrial applications, from manufacturing to oil and gas production. In this blog post, we will explore the different types of pumps available, factors to consider when choosing a pump, applications of pumps in different industries, and common pumping problems, along with troubleshooting tips. Whether you're an engineer or simply interested in learning more about pumps, this...

As an industrial plant operator, you know that noisy water pumps can cause a whole host of problems. From disrupting the work environment to indicating potential malfunctions, it's essential to address any loud pump noises as soon as possible. But how do you go about quieting these essential machines? In this article, we'll share our expert tips for reducing pump noise and ensuring your plant runs as smoothly as possible.

What causes a noisy water pump?

As industrial plant operators, you know the...

Pump vibration analysis is a crucial aspect of effective maintenance for industrial pumps. Vibrations can indicate wear and tear, alignment issues, and other potential problems that, if left untreated, can lead to costly downtime and repairs. As plant engineers and pump maintenance technicians, it's essential to understand the importance of pump vibration analysis and how it can help you identify and address issues before they become major problems. In this article, we'll explore the basics of pump...

A discharge gauge that reads "too low" triggers a chain of bad decisions — valve adjustments, speed changes, even premature pump replacement — if the number is misinterpreted. The gauge does not tell you whether the pump is healthy. It tells you where the pump and the system agreed to operate at that moment. Misreading that agreement costs downtime and money.

This article gives you a direct path from the gauge reading to the pump curve: how to convert pressure and head correctly, what shifts the...

You are watching the kWh meter climb while your throughput stays flat — or drops. You swap the impeller, adjust the VFD, and hope the next month looks better. It does not. The pump still runs, the motor still draws, but the cost per ton moved keeps rising.

That is not a pump failure. It is a system efficiency problem that a pump swap cannot fix.

This article gives you a field-tested method to diagnose why your slurry pumping efficiency is falling, separate system losses from pump degradation, and...

As a result of conservative engineering practices, pumps are often substantially larger than they need to be for an industrial plant’s process requirements. Centrifugal pumps can often be oversized because of  “rounding up,” trying to accommodate gradual increases in pipe surface roughness and flow resistance over time, or anticipating future plant capacity expansions. In addition, the plant’s pumping requirements might not have been clearly defined during the design phase.

Because of this conservative...

A pump’s efficiency can degrade as much as 10% to 25% before it is replaced, according to a study of industrial facilities commissioned by the U.S. Department of Energy (DOE), and efficiencies of 50% to 60% or lower are quite common. However, because these inefficiencies are not readily apparent, opportunities to save energy by repairing or replacing components and optimizing systems are often overlooked.

Define Pumping System Efficiency

System efficiency incorporates the efficiencies of the pump,...

Overview 

Centrifugal pumps handle high flow rates, provide smooth, non pulsating delivery, and regulate the flow rate over a wide range without damaging the pump. Centrifugal pumps have few moving parts, and the wear caused by normal operation is minimal. They are also compact and easily disassembled for maintenance. The design of an efficient pumping system depends on relationships between fluid flow rate, piping layout, control methodology, and pump selection. Before a centrifugal pump is selected,...

Every industrial facility has a piping network that carries water or other fluids. According to the U.S. Department of Energy (DOE), 16% of a typical facility’s electricity costs are for its pumping systems. 

The power consumed to overcome the static head in a pumping system varies linearly with flow, and very little can be done to reduce the static component of the system requirement. However, there are several energy- and money-saving opportunities to reduce the power required to overcome the...
