Chemical Pump Seal Form:

Oil seal seal is a kind of self-tightening lip seal, its structure is simple, small size, low cost, easy maintenance, small resistance torque, can not only prevent medium leakage, but also prevent the invasion of external dust and other harmful substances, and has a certain ability to compensate for wear, but not resistant to high pressure, so it is generally used in chemical pumps in low-pressure occasions.

Gasket seal, gasket is the basic element of static sealing of centrifugal pumps, and it is used in a wide range of applications. The selection of gaskets is mainly determined by factors such as the medium, temperature, pressure and corrosiveness of the chemical pump.

There are generally two types of chemical pumps commonly used: centrifugal pumps and reciprocating pumps. Chemical centrifugal pumps and diaphragm pumps are common chemical pumps at present.

Centrifugal pump (type of centrifugal pump commonly used in chemical industry).

According to the nature of the transported liquid, the centrifugal pumps commonly used in chemical production mainly include water pumps, corrosion-resistant pumps, oil pumps, submerged pumps, impurity pumps, and shielded pumps. Corrosion-resistant pumps are mostly small pumps, which are mainly used to transport corrosive liquids such as acid, alkali and concentrated ammonia, and it is also its corrosion-resistant characteristics, so corrosion-resistant pumps must be used when transporting these corrosion-resistant items; The oil pump is mainly used to transport petroleum products, so the sealing performance of the oil pump must be good. Submerged pumps have a wide range of applications, submerged pumps are often installed in liquid storage tanks, and they can also transport various corrosive liquids, however, submerged pumps have a disadvantage, that is, the efficiency is relatively low; The impurity pump is mainly used to transport some suspensions containing solid particles, thick slurry and other items, which has the characteristics of not easy to block, easy to disassemble, wear-resistant, etc., and there are many types of impurity pumps, including sewage pumps, sand pumps, mud pumps, etc.; Shielded pumps, also known as non-leakage pumps and sealless pumps, are mainly used to transport flammable, explosive, highly toxic or emitting substances, but their efficiency is also relatively low.

Pumps commonly used in the chemical industry are mainly centrifugal pumps, and others are: gear pumps, piston pumps, reciprocating pumps, diaphragm pumps, impeller pumps, pipeline pumps, jet pumps, vacuum pumps, etc.

Chemical pump is a kind of mechanical equipment used to transport various chemical substances, corrosive media and liquids, mainly used in petrochemical, metallurgy, pharmaceutical, food, water treatment and other fields. The main characteristics of chemical pumps are corrosion resistance, high temperature, high pressure, high efficiency, compact structure, easy operation, stable operation and high reliability.

According to their working principle and structural form, chemical pumps can be divided into centrifugal pumps, positive displacement pumps and other types of pumps. The centrifugal pump sucks the liquid into the pump through centrifugal force, and then pushes the liquid out of the pump body through the rotor rotation, its main characteristics are large flow and stable pressure, and it is suitable for transporting clean water, waste water, oil and some corrosive liquids in the middle of the shed. A positive displacement pump is a pump that works based on the principle of volume change, and its main feature is that the flow rate and pressure are stable, and it is suitable for conveying viscous liquids, highly solids liquids and corrosive liquids.

Technical standards for chemical pumps usually include parameters such as operating temperature range, pressure, flow rate, material, shaft seal type, noise, etc. At the same time, the design, manufacture, installation and use of chemical pumps also need to comply with relevant national standards and safety specifications.

Chemical pump is a national joint set of energy-saving pumps, pump performance, technical requirements, according to the international standard ISO2858 specified in the performance and size design, its advantages: the full range of water conservancy performance layout is reasonable, the user choice is wide, "rear open" structure, easy maintenance, efficiency and suction lift to reach the international advanced level. Chemical Pump Classification:

Stainless steel chemical pumps, plastic chemical pumps, fluoroplastic chemical pumps, electric chemical pumps, pneumatic chemical pumps.

Chemical pumps are used to transfer chemicals and are designed for corrosion resistance and abrasive industrial liquid fuels, paints, bleach, solvents, etc.

Chemical pumps can be centrifugal or positive displacement pumps depending on the application. The most common chemical centrifugal pump for rent and sale is the ANSI process pump, which is a single-stage end suction pump.

Many chemical pumps are also positive displacement pumps, progressive cavity pumps, utility pumps, diaphragm pumps, or piston pumps. These pumps are used to move liquid chemicals at high pressures.

We are accustomed to calling the pumps that are usually used to suction some corrosive and moderate media and chemical solvents and media as chemical pumps.

In the world, there are certain standard bricks for chemical pumps, which must meet certain design requirements and design specifications, and their own performance and structure must meet the specified standards.

Pumps commonly used in the chemical industry include:

Centrifugal pump: Centrifugal pump is a commonly used pump, suitable for transporting low-viscosity liquids, with the advantages of simple structure and easy to use.

Self-priming pump: A self-priming pump is a pump that can suck the medium by itself, suitable for conveying low-viscosity liquids, quick to start and easy to use.

Magnetic pump: Magnetic pump is a pump suitable for transporting corrosive, toxic, harmful, flammable and explosive and other special media, with the advantages of no leakage and compact structure.

Screw pump: The screw pump is suitable for conveying high-viscosity liquids, liquids containing more solid particles, etc., and has the advantages of large conveying flow and high conveying accuracy.

Submersible pumps: Submersible pumps are suitable for transporting high-temperature liquids containing solid particles, and are often used in sewage treatment, mine drainage and other fields.

Mixed-flow pumps: Mixed-flow pumps are suitable for conveying medium-flow and medium-head liquids, and have the characteristics of wide flow range, high efficiency and long service life.

2. Oil pump: The oil pump is a kind of pump that is both light and compact, and there are three categories: in-line, distribution and monolithic. The oil pump needs a power source to operate, and the camshaft at the lower part of it is driven by the engine crankshaft gear.

3. Impurity pump: The transmission mode of the pump is connected with the motor through the elastic coupling components. From the direction of the motor, the pump rotates in a clockwise direction.

4. Submerged pump: Submerged pump is a positive pressure conveying vertical pump, which can effectively solve the problems of gas resistance and cavitation. The explosion-proof level of the conveyed material determines that the submerged pump products have different structures, working principles, classifications, scope of application, product advantages and disadvantages and operation methods, which can be simply divided into two categories: traditional submerged pumps (explosion-proof in zone 1 outside the tank, non-explosion-proof in zone 0 in the tank) and new submerged pumps (explosion-proof in zone 1 outside the tank and explosion-proof in zone 0 in the tank).

5. Shielded pump: The drive of the ordinary centrifugal pump is to connect the impeller shaft of the pump with the electric shaft through the coupling, so that the impeller and the motor rotate together and work, while the shielded pump is a sealless pump, the pump and the drive motor are sealed in a pressure vessel filled with pumped medium, this pressure vessel is only statically sealed, and a wire group is used to provide a rotating magnetic field and drive the rotor.
