WHAT TO CONSIDER WHEN SELECTING A CENTRIFUGAL PUMP THE TYPES TO CHOOSE FROM AND THE FEATURES TO LOOK OUT FOR Selecting a centrifugal pump for your process is no easy task. There are various options available, each with their own advantages and disadvantages. Ultimately, the optimal pump for your operation will depend on the nature and location of your business. That being said, there are a few important factors every business owner will have to mull over before deciding on a pump. BASE-MOUNTED OR INLINE The two major types of centrifugal pumps are base-mounted and inline models. As the name suggests, base-mounted models come with all of their components mounted on a common base. Inline models, on the other hand, are traditionally mounted directly in the piping line. Inline options tend to be smaller but carry a lower operating cost. It’s worth noting that if you’re in an area with a high instance of seismic activity, base-mounted pumps are the safer and more reliable option. SINGLE OR DOUBLE SUCTION In general, HVAC applications exceeding 2,000 gallons per minute (GPM) or requiring a pump larger than 8 inches should consider a double suction pump. Single suction pumps are cheaper to install and easier to maintain than their double suction counterparts, but they’re not without drawbacks. Because they only have one suction source, they’re prone to wear and tear caused by axial thrust, which gives them a much shorter lifespan than double suction alternatives, which can last up to 30 years. SAFETY AND PERFORMANCE CONSIDERATIONS In addition to understanding the differences between styles of pumps, there are a few things that you should ask about, regardless of the unit you select. Perhaps the most important piece to ask about is an OSHA-approved coupler guard. Without one, operators are at risk: dangling items could get caught in the coupler, which can lead to serious injury.

For Walsh, preparation for leadership begins by bracing yourself for the worst. A mantra repeated throughout the book is “expect defeat.” In business and in football, losses are just a fact of life; how you prepare for and respond to these crises will determine your team’s overall success. But the most valuable element of leadership in Walsh’s eyes is how you treat the members of your team. You need to have the courage to let them know you believe in them. Using simple but earnest positive reinforcement, this legendary coach turned the 49ers into an incredible team, and the benefits show. Segments of the book contain anecdotes and reflections from players such as Joe Montana and Randy Cross, whose deep admiration for their former leader speak volumes. “The Score Takes Care of Itself” was published posthumously. Walsh’s son, Craig, did much of the legwork to piece this definitive portrait together. What we are left with is a truly insightful read from one of the most innovative, inspiring minds in sports history. It will be a long time before a book like this comes around again.

From a performance perspective, it’s important to align your pump in a way so as to limit elbows, which decrease performance and exert high levels of pressure on impellers. These are far from the only characteristics to think about when selecting a centrifugal pump, but starting with these considerations will set you on a path to successfully choosing the best option for your business.
