Tips for Correcting Pump Shaft Misalignment
October 11, 2023 |
Proper alignment is critical for the efficient and reliable operation of pumps in various industries. When a pump’s shaft and its driver (such as an electric motor or engine) are not correctly aligned, it can lead to premature failure, unscheduled downtime, and damaged components. Whether you’re a seasoned maintenance professional or new to pump maintenance, […]
Read MoreWhat Role Do CO2 Transportation and Injection Pumps Play in ESG?
November 14, 2022 |
Modern industries can achieve environmental, social, and governance (ESG) goals through carbon capture and storage. With an ever-increasing drive for the safe handling of industrial and commercial emissions, CO2 injection pumping has become increasingly popular. This article considers how pumping carbon dioxide underground helps to lower undesirable emission levels. The Importance of ESG Initiatives Implementing […]

April 14, 2021 |
How many times are pump operators forced to modify fasteners that are used to secure motors and/or pumps to baseplates? A warehouse spare is ready to be installed and nothing fits, i.e alignment is not successful, major piping does not bolt up cleanly, and operations are anxiously awaiting their new equipment. Chain falls and come-alongs […]

PUMP SPECIFIC SPEED
SUCTION SPECIFIC SPEED
March 31, 2021 |
Design engineers find composite measurement parameters useful for selecting solutions to engineering problems. These measurement parameters are dimensionless numbers that provide excellent design tools. Fluid engineers use Reynold’s Numbers, while heat transfer engineers use Prandtl and Nusselt numbers. Pump engineers use two closely related dimensionless parameters: specific speed and suction specific speed. Both parameters relate […]

March 16, 2021 |
If a pump operator is fortunate to have equipment with long service life and high reliability, very often the temptation is to overlook these units and focus on other units that are not performing so well. Do not be deceived! A high reliability focused organization will look ahead to potential problems. One area of potential […]

Horizontal Pump Bearing Housing Lubrication Method
February 26, 2021 |
RING-FED LUBRICATION Whether horizontal pump shafts are supported by rolling element bearings, journal bearings, or a mixture of both, lubrication is critical for maintaining their reliability. This discussion will not focus on lubricating quality (viscosity, type of lubricant, contamination, etc.), but rather on lubricating levels and more specifically, maintaining a constant level. I recall a […]
Read MoreThe Role of Temperature in Pump Selection
February 12, 2021 |
The anticipated temperature range that a pump will need to handle during operation is crucially important to making the right choices about not just which pump to install, but what kinds of components should be installed along with it. Although temperature seems like a familiar concept, in industrial applications it can quickly get complicated. How […]
Read MoreExplaining the Limitations and Benefits of Operating Two Pumps in Series
October 25, 2018 |
The term “Pumping in Series” means that one pump acts as a booster to feed another pump. The purpose of operating pumps in series is that, at the same flow rates, the Head (differential pressure) of both pumps is additive. As a result, two smaller pumps in series may offer a lower cost, lower power, […]
Read MoreChill Out: PumpWorks Group 2 Process Pump Wins Competition
November 9, 2017 |
PumpWorks recently tested a Group 2 PWA (B73.1 ANSI Process Pump) in a head to head comparison with a major competitor. Our principle area of study for this test was how the Powerframe manages heat. Heat is generated by the bearings and transferred through conduction from the process fluid to the Powerframe. The Powerframe operating […]

October 10, 2017 |
Pumpworks introduced a complete line of API 610 BB5 barrel pumps. API 610 11th Edition states that unless otherwise specified, pumps with radially split casings are required for any of the following operating conditions: A pumping temperature of 200 °C (400 °F) or higher (a lower temperature limit should be considered if thermal shock is probable) […]
