Chemical pumps: scope of use

Chemical pumping equipment is used in various spheres of life. There are many kinds of such units. The main purpose of pumps is to transfer aggressive liquids. It can be like all kinds of acids, toxic substances, corrosive and abrasive liquids, and liquefied gases.

All of the above aggressive liquids are endowed with such negative qualities as toxicity, explosiveness, propensity to polymerization, uncontrolled temperature, etc. Therefore, the chemical equipment for pumping is made of high-strength polymers that are resistant to chemical processes. The central type of mechanisms is the most in demand. This type of pumping equipment is produced in different designs. Pumps are divided into:

• Console;
• Vertical;
• Vortical;
• Submersible;
• Monoblock;
• Sectional;
• Sealed;
• Horizontal;
• Multistage.

Hermetic centrifugal pumps are used in the chemical sphere. Aggregates can pump not only corrosive and corrosive environments. The mechanisms are perfectly suited for operation under conditions of high pressure, vacuum, low and high temperatures. The flow-through part of the units must be made of tested materials. Their service life depends on the service life of the unit. Modern chemical pumps are equipped with a flowing part made of:

• Chrome-nickel-molybdenum steel;
• Chrome or siliceous high-alloyed cast iron;
• Chrome nickel;
• High-strength polypropylene.

The type of seal affects not only the quality, but also the tightness of the pumping equipment. There is a seal between the electric motor and the pump part. The equipment has both advantages and disadvantages. Advantages, of course, more. It:

• Ease of use and adjustment;
• Compactness;
• Light weight;
• Relatively inexpensive price;
• Economy;
• reliability.

Pumps work quietly, smoothly, which protects the device from sudden hydraulic jumps.

Deficiencies include restrictions that prevent the use of equipment in certain production environments.

The market of chemical aggregates is quite wide. The economic, environmental, and food security of the state depend on their capacity and quality. Such equipment is used in various spheres of life. It:

• chemical production;
• Pharmaceutical sphere;
• Production of paper;
• Housing and communal services;
• textile industry;
• Production of paint and varnish materials;
• nuclear power.
