Diaphragm pumps are designed in three major archetypes:1. Xylem is now a multi-billion dollar company offering incredible solutions for water transportation, pump analysis, and industrial water needs. In this way, this type of pump utilizes its own energy to continue pumping liquid on both sides of the pump.2. Dual Diaphragm Pumpsa.industrialzone.4. The seal also grants a great boost to safety for this type of pump in regards to accidental leaking. What Is the History of Flojet as a Product?Flojet was founded in 1975 to design and manufacture special use pumps, primarily focused around machines used for cleaning (car wash pumps, soap pumps, and more). Xylem offers water products internationally as well.Diaphragm pumps are also remarkably good at handling viscous fluids and/or fluids with particulate contained within. How Do Flojet Diaphragm Pumps Function? Diaphragm pumps, which sometimes go by the name of “membrane pumps,” are a type of positive displacement pump (PDP) which employ rubber membranes to pump fluids through a system of valves. What Are the Strengths of Flojet Diaphragm Pumps? Because diaphragm pumps form hermetic seals, they do not generally require lubricants for the pump itself (though, of course, any connected machines may require lubricants). The hydraulic fluid will be pressurized in such a way that it stretches the rubber, the release of which pulls fluid into the pump.This article will explore the function, strengths, and weaknesses of the Flojet Diaphragm Pump and diaphragm pumps in general, as well as offer a little bit of the history of such pumps.
