Pump manufacturers publish different values for minimum flows in technical publications or on performance curves, but what does it all mean, and what should pump operators do with this information? Is there a difference between minimum flow and minimum continuous stable flow (MCSF)? What happens if you pump below these stated values? And what are some ways to protect your…

API 610 is the American Petroleum Institute’s standard for ultra-reliable process pumps. The standard was born out of the needs of refineries, which no doubt present some of the most difficult conditions—high-temperature hydrocarbons with very high reliability and safety requirements. Although refinery pumps are in API 610’s DNA, the standard is applied in a variety of other industries and processes…

Close-coupled centrifugal pumps are attached directly to the face of a motor. They use the motor’s bearing and shaft, which makes these pumps more compact and economical. By contrast, frame-mounted pumps have their own bearing frame. For some applications, close-coupled centrifugal pumps are the clear best choice due to the lower cost and a smaller footprint. In this article, we…

A Boiler Feedwater Pump is an essential component of a boiler system. Without it, feedwater from the tank cannot be transferred to the boiler. Depending on the operation requirements, boiler feedwater pumps control and regulate the input of the feedwater. Now, getting a boiler pump is not as simple as ordering online or going into a store to buy one.…
