Progressive Cavity Pump is a type of positive displacement pump which has a rotor rotating within a housing called a stator. The rotor is always metallic and the stator is made up of a rubber type of material. It looks somewhat like a screw thread the fluid is between the cavities and the rotary motion of the rotor forces the fluid through from one end to the other. The liquid acts as the lubricant between the pumping elements,� and it should not be run dry.

Submerged pump [1] is a positive pressure conveying vertical pump, which can effectively solve the problem of air resistance and cavitation. The explosion-proof level of the conveyed material determines the submerged pump products with different structure, working principle, classification, scope of application, product advantages and disadvantages and mode of operation, which can be simply divided into two categories of traditional submerged pumps (explosion-proof outside the tank 1 area, 0 area inside the tank is not explosion-proof) and new type of submerged pumps (explosion-proof outside the tank 1 area, explosion-proof inside the tank 0 area).
Submerged pumps are vertical pumps in which the impeller, pump body, and other flow-through parts are submerged in the material being conveyed, and are connected to the motor by a shaft. Submerged pumps are made according to the different needs of reaching into the length of the container. Submerged pump and material contact parts, generally according to the requirements of the material selection, metal and non-metallic materials. Such as 304, 316, 316L, engineering plastics, fluorine plastic and so on.
Diaphragm pumps are designed to protect columns and cylinders by separating the liquid being pumped from the columns and cylinders with the aid of a membrane. The left side of the diaphragm in contact with the liquid are made of corrosion-resistant materials or coated with a layer of corrosion-resistant substances; the right side of the diaphragm is filled with water or oil.
Diaphragm pumps, also known as control pumps, is the main type of actuator, by accepting the control signal output from the regulator control unit, with the help of power operation to change the fluid flow. Diaphragm pump in the control process is to accept the regulator or computer control signals, change the flow of the regulated medium, so that the regulated parameters are maintained in the required range, so as to achieve the automation of the production process. If the automatic adjustment system compared with the artificial adjustment process, the detection unit is the human eye, regulation and control unit is the human brain, then the implementation of the unit - diaphragm pump is the human hand and foot. To achieve the process of a parameter such as temperature, pressure, flow, level and other regulatory control, are inseparable from the diaphragm pump.
Air operated diaphragm pumps are commonly used in five materials: plastic, aluminium alloy, cast iron, stainless steel, Teflon. Electric diaphragm pumps have four materials: plastic, aluminium alloy, cast iron, stainless steel. Diaphragm pump diaphragm according to different liquid media were used nitrile rubber, neoprene, fluorine rubber, PTFE, PTFE, etc. placed in a variety of special occasions, used to pump a variety of media to meet the needs.

Slurry pump refers to speak refers to through the use of centrifugal force (pump impeller rotation) role of solid, liquid mixed media energy increase of a mechanical, electrical energy into the medium of kinetic energy and potential energy of the equipment. Mainly used in: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum and other industry sectors.
Slurry pump conveys a mixture of solid particles containing dross and water. But from the principle of slurry pump belongs to a centrifugal pump, in the iron and steel enterprises are mainly used for converter dust water, blast furnace gas scrubbing water, continuous casting turbid ring water and rolling steel turbid ring water and other systems of slurry transport.
