Rotary pumps – pumps it out family "volume of action", which we talked a little higher. As you know, the main working element of the rotary pumps themselves are the rotors. Due to the rotors is forced displacement of the liquid. Shift comes at a time when the rotors, as well as cams and wedges are in motion. It is noteworthy that rotary pumps do not require the intake / suction valve. In addition, it is necessary to note the benefits of the next representative of the family of volumetric pump – is a gear pump. To date, gear pumps are classified into two types: – pumps with external gearing gears – pumps with internal meshing gears before we start looking at the advantages and disadvantages of each let's give a description of the most gear pump.

Gear pumps as well as use the principle of compulsory rotary displacement fluid. However, unlike the rotary gear pump, a different work item – a set of gears that are coupled to each other. One gear is leading, the second slave. Gear Pumps are easy to use and relatively inexpensive. Gear pumps with internal teeth of gears are arranged in such a way that "home" is located inside the gear pinion, while the pumps with an external meshing gears do not give a trace. It is important to say that the gear pumps have several advantages and disadvantages.

The advantages of these pumps include: – High pressure, which can create gear pumps – pumping ability of the various types of liquids, including high-temperature liquid. – Relatively high cost – Ability to control fluid flow to change direction transfer fluid. – The ease and convenience of operation as you can see, gear pumps have a long list of advantages and disadvantages of the two. Then we'll talk about impeller pumps. Impeller pumps have a rotor, which is located on the surface of the blade, which are made of special elastic material. It must be said that the blades are working (spinning) directly inside the eccentric housing. This contributes to the elasticity of the blades, which eventually bend and literally squeeze the liquid from the pump. Impeller pumps are self-priming, which allows them to easily pump any viscous fluid. The next object of our consideration will be the cam pump, which, incidentally, has two rotors. They provide the movement of fluid within the working chamber. In the manufacture of cam pumps much attention is paid to production of housing for the pump. Why? Yes, because it depends on the value gap between the two rotors. It is these gaps to prevent the direct penetration of the liquid inside the pump. Claw pumps are used for food or for making beverages. Sometimes the cam pumps can be used to produce pharmaceuticals. No less interesting in terms of Fluid Handling Solutions is a peristaltic pump. Operates the pump through a special multi-layer elastomeric sleeve. Peristaltic pumps are simple and very efficient design, which By the way, is not afraid to care "dry" method. As well as gear pumps peristaltic have the opportunity to change the fluid flow in either direction. Simultaneously, peristaltic pumps are capable of working with abrasive and aggressive substances that are not important enough. As a result, this article would like to say that the industry pumps are indispensable in the manufacture of various products and materials. That is why today as industrial pumps demand in the industrial sphere.
