NPSHr and Vertical Pumps: What You Need to Know
Net positive suction head required (NPSHr) is one of the most important measurements for a pumping system. It allows you to set key performance standards and indicators for optimal operating efficiency. Of course, most pumps are horizontally oriented, and the method for determining NPSHr is standard. What about vertical pumps, though? How Do You Determine […]
How to Winterize Your Pump System
When you are located in a cold-weather area, winterizing your water pump system will prevent pipes from freezing, seals from cracking, and significant damage from occurring. Whether you are running the pump system or shutting it down for the season—even in areas with warmer climates—there are winterization strategies that will keep your pump system safe. […]
How to Minimize Shaft Seal Leakage
As a pump operator, you often have to troubleshoot problems. However, with more experience and extended use of pump equipment, you can start to anticipate issues long before they happen. One very widespread concern with pump systems is leakage between the shafts and mechanical seal sleeves. This area can be a weak point in many […]

The 3 Most Common Reasons for Pump Failure
Why do pumps fail? These intricate pieces of equipment take quite the beating every day, working hard to ensure your operation runs smoothly. Typically, the bearings, couplings, and seals are first to experience damage, so it’s essential to understand these vulnerable parts. Understanding what causes failures and how to address them will create a more […]
Why You Must Consider NSPH
When centrifugal pumps stop operating at peak performance, there are several potential issues at hand. Seals, couplings, shaft alignment, and bearings are areas that need inspecting. Experienced pump operators also consider net positive suction head (NPSH), primarily when cavitation occurs. Some in the pump industry joke that NPSH stands for “not pumping so hot,” because […]
How to Precisely Monitor a Metering Pump’s Turndown
Accuracy is vital when you have a chemical dosing application for chemical manufacturing, water treatment, or oil and gas. Turndown ratio is the key measurement you will use to determine precision metering. The acceptable turndown ratio should have a tolerance of no more than ±1.0%. After that, there is not much wiggle room. What is […]
Improve Valve Safety in High-Pressure Applications
When transferring high-pressure fluids, maintaining pump safety deserves extra attention. Seals and valves should properly function as pressures rise. If not, you face the risk of catastrophic equipment failure and a serious safety concern. Valve Packing Maintenance Proper valve packing maintenance is critical as part of an overall pump system maintenance schedule. Valve packing is […]
