At present, the diaphragm pump is the most widely used in the domestic process pump: centrifugal pump, gear pump and so on. But with the development of production technology and production process and the product quality request more and more high, with many in the production process of centrifugal pump, gear pump has been unable to meet the request of product function and quality of the modern transport pump, a new principle is the inevitable result to replace old type pump.

      the centrifugal pump of the diaphragm pump has low power, high energy consumption and high operating cost (only 40% of the power). It has lower power and even can't operate in occasions with larger viscosity and higher discharge pressure. Although the power of heavy oil pump and gear pump is relatively high in the process of material transportation, there are also some defects, such as no wear resistance, no operation, large volume of repair operation, and difficult to clean. And the delivery process is not satisfactory in transporting the corrosive medium or the medium with the cleaning request.

        diaphragm pump screw pump compared with gear pump, centrifugal pump has clear advantages, less vulnerable parts, easy and convenient repair is a major advantage.

Diaphragm pump rotor pump completely without the above defects, the rotor pump in actual operation process has not made of stainless steel materials damageable parts, basic operation free protection, the cleaning process is simple and not dead, and all the parts can be satisfied by touch the material properties of the materials, cleaning, corrosion resistance, easy to clean, less protection, high pressure other characteristics are shown for its strong function, because the operating principle of common rotor pump in the conveying of materials with high viscosity and volatility material is more significant advantages, is not the other way to replace the pump.

Diaphragm pump rotor pump has the characteristics of good transport, on some easy sensitivity materials transport properties on the formation of the material will not damage, so in the delivery of those activities is not easy to medium such as paste or sensitive materials such as yeast, easy to transport materials such as yogurt, a rotor pump is the best choice.

Diaphragm pump rotor pump whether delivery of fluid mediums such as water, transportation is still like gum base viscosity up to 1000000CP, whether it is transporting corrosive chemical raw materials, is still carrying food, medicine has strict request clean goods, can be served, is truly universal delivery pump.
