Picture 1 is an animated picture for easier understanding .Adjustable speed knob dial Precision pump works great seems powerful .Loop a hose through the top it will self prime a long ways non contact rollers design means no cleanups or contamination .One of the best possible pumps available . Push pull action non contamination no contact . Silent strong pump unit .Probably a great drinking water pump .120 volt wall plug Maybe a 3/8" or 1/2" hose Many uses like blood oil gas sterile water labMake an offer on this neat machine First good offer gets itAsk if anything A peristaltic pump is a type of positive displacement pump used for pumpinga variety of fluids. The fluid is contained within a flexible tube fitted inside acircular pump casing (though linear peristaltic pumps have been made). Arotor with a number of "rollers", "shoes", "wipers", or "lobes" attached to theexternal circumference of the rotor compresses the flexible tube. As the rotorturns, the part of the tube under compression is pinched closed (or"occludes") thus forcing the fluid to be pumped to move through the tube.Additionally, as the tube opens to its natural state after the passing of thecam ("restitution" or "resilience") fluid flow is induced to the pump. Thisprocess is called peristalsis and is used in many biological systems such asthe gastrointestinal tract. Typically, there will be two or more rollers, orwipers, occluding the tube, trapping between them a body of fluid. The bodyof fluid is then transported, at ambient pressure, toward the pump outlet.Peristaltic pumps may run continuously, or they may be indexed throughpartial revolutions to deliver smaller amounts of fluid.ApplicationsPeristaltic pumps are typically used to pump clean/sterile or aggressivefluids because cross contamination with exposed pump components cannotoccur. Some common applications include pumping IV fluids through aninfusion device, aggressive chemicals, high solids slurries and othermaterials where isolation of the product from the environment, and theenvironment from the product, are critical. It is also used in heart-lungmachines to circulate blood during a bypass surgery as the pump does notcause significant hemolysis.Peristaltic pumps are also used in a wide variety of industrial applications.Their unique design makes them especially suited to pumping abra ApplicationsPeristaltic pumps are typically used to pump clean/sterile or aggressivefluids because cross contamination with exposed pump components cannotoccur.
