Effective pump maintenance allows industrial plants to keep pumps operating well, to detect problems in time to schedule repairs, and to avoid early pump failures. Regular maintenance also reveals deteriorations in efficiency and capacity, which can occur long before a pump fails. Wear ring and rotor erosions, for example, can be costly problems that reduce wire-to-water efficiency by 10% or more. 

The amount of attention given to maintenance depends on how important a system is to a plant’s operations...

Pumping system control valve inefficiencies in plant processes offer opportunities for energy savings and reduced maintenance costs. Valves that consume a large fraction of the total pressure drop for the system or are excessively throttled can be opportunities for energy savings. Pressure drops or head losses in liquid pumping systems increase the energy requirements of these systems. Pressure drops are caused by resistance or friction in piping and in bends, elbows, or joints, as well as by throttling...

In the United States, more than 2.4 million pumps, which consume more than 142 billion kWh annually, are used in industrial manufacturing processes. At an electricity cost of 5 cents per kWh, energy used for fluids transport costs more than $7.1 billion per year. Even one pump can consume substantial energy. A continuously operated centrifugal pump driven by a fully loaded 100-horsepower motor requires 726,000 kWh per year. This costs more than $36,000, assuming average electricity costs of 5 cents...

In pumping applications with variable flow rate requirements, adjustable speed drives (ASDs) are an efficient control alternative to throttling or bypass methods. ASDs save energy by varying the pump’s rotational speed. In centrifugal pumping applications with no static lift, power requirements vary, as the cube of the pump speed and small decreases in speed or flow rate can significantly reduce energy use. For example, reducing the speed (flow rate) by 20% can lower input power requirements by approximately...

Let's talk about centrifugal pump impellers. These little guys are the backbone of any pumping system, and it's important to keep them happy if you want your system to run smoothly. Unfortunately, one of the biggest culprits of energy waste and lost efficiency is impeller clearance. But don't worry, as a mechanical engineer, you've got the skills to tackle this problem head-on. In this guide, we'll show you how to keep those impellers in top shape and make sure your pumps are running at their best....

As engineers, you know how important pumps are for industrial processes to run efficiently. However, when cavitation rears its ugly head, it can quickly undermine even the most advanced pump systems. Cavitation can cause damage to pump components, reduce efficiency, and increase downtime, resulting in significant losses for your company and headaches for you.

At the Pump Systems Academy, we've seen how challenging cavitation can be for maintenance and operations professionals in mining and other...

When exploring and learning about pumping systems, I was amazed at the information available online today in 2021.  For a non-engineer, there are numerous sites that provide incredibly easy to read and understand information.  The U.S. department of energy has done an excellent job with their tear sheets.  I’ve provided the information that they teach, as it’s an incredibly reliable resource:

Most pumps operating today were selected to meet a maximum system demand, or potential future demands....
