about Larry

 

Many people call Larry ‘The Pump Guy’. Larry writes the ‘Pump Guy’ column in Flow Control Magazine, World Pumps Magazine, Mechanical Technology Magazine and to some 40,000 monthly newsletter subscribers. A few of The Pump Guy articles are available on our articles page. Larry writes like he talks. If you like the articles, you will love his books "Know and Understand Centrifugal Pumps" and “Centrifugal Pumps and Everything You Need to Know About Pumps” written in both English and Spanish versions (“Bombas Centrífugas, y Todo lo que Necesita Saber Sobre Ellas”).

Larry continues inventing products when not lecturing and consulting. As a member of ASME (American Society of Mechanical Engineers), most of Larry’s products find application in civil and mechanical engineering.

A number of years ago, while working in a petrochemical plant, Larry encountered some premature pump failure, linked to the O-rings installed in the mechanical seals. In collaboration with some intelligent associates, trips to the library, and a chance witnessing of his young daughter bouncing a rubber ball in the house, Larry hit upon the seeds of the tool that broke the code on O-Ring identification. Larry mortgaged his house to finance the development of the device. Today that tool is called the ORID®. ORID is an acronym meaning O-Ring Identifying Device. Today the ORID is a standard tool used by hydraulic and pneumatic technicians, pump mechanics and instrumentation techs all over the world. The tool is purchased by governments, militaries, aviation and space companies, manufacturers of pumps, valves, seals, compressors, and all equipment that contains liquids and gases.

The ORID performs a non-destructive field test of an O-Ring seal to indicate its rubber compound and compatibility with a fluid, gas, or solid. This tool, sold around the world, is instrumental in preventing leaks in process equipment, and protecting the environment.

Again, while working with pumps, this time in a paint factory, Larry realized that some pumps must, by design and circumstances, work under cavitating conditions. Most pump literature says to avoid cavitation and inadequate NPSH. This is somewhat like you doctor telling you to get 8-hours of sleep, or the Highway Department telling you to avoid traffic accidents. Sometimes you can…and sometimes you can’t. Some pumps are forced to operate under cavitating conditions. Once again, working with intelligent associates, trips to the library, and an insatiable desire to conquer problems, and circumstances, Larry put together the prototype of the product that was to become the TURBO TANK®. The original TURBO TANK was made from a 5-gallon bucket, a 12-volt battery, and an automobile windshield washer pump. Both Larry, and the maintenance manager at the paint factory, were amazed to witness destructive cavitation venting its force against a process pump seal… month after month… with no effect. Once again Larry mortgaged the house and emptied the savings account to finance the project.

Today, the TURBO TANK double seal support system, is tripling and quadrupling the service life of industrial rotating equipment and mechanical seals. Some of the original TURBO TANKs are running more than 15 years with no seal failure, under obviously cavitating conditions. The successful TURBO TANK is now in its fifth generation.
