THE APPLICATION OF THE MONTH! ESPANGO PERISTALTIC PUMPS - IPI SERIES
Espango peristaltic pumps are the result of our studies, construction, development and updating. We can boast more than 50 years experience during which we have been able to develop the right solution to the multiple needs of our numerous and loyal customers.
The peristaltic pumps we produce are used to transfer some of the most difficult liquids and chemicals present on the market, but the pumping action is delicate; this makes the Espango peristaltic pump suitable for working with cut sensitive products such as technopolymers and it allows the passage of solid bodies or full-bodied ingredients that must remain intact, see food production.
We equip our peristaltic pumps with highly abrasion-resistant tubes, designed for two or three rollers, without replacing the steel or aluminum disc support on which they are mounted.
The size combination of the heads, tubes sizes, motors, adapters, mechanical variators or electronic frequency converters, horizontal or vertical development, carts etc. allow us to offer our customers a range of capacities that make our Espango peristaltic pumps suitable for the use in laboratory sector up to mining applications.
How does a peristaltic pump work?
The peristaltic is a volumetric pump used for the transfer and/or the dosing of a wide variety of fluids.
The liquid is contained inside a special tube housed in the pump body or cradle. The pumping principle, peristalsis, is based on alternating compression and relaxation of the tube; this action allows to suck and pump out the contents. The rotating roller (in our case two or three) slides along the tube and creates a temporary seal between the suction and the delivery or discharge of the pump. When the disc with the rollers rotates, this holding
pressure moves along the tube, forcing the product to be transferred to move from the pump to the discharge or delivery. When the pressure (crashing) is released, the tube revives, creating a vacuum that attracts the product to the suction side.
