Chemical pumping equipment is used in various fields of life. There are a lot of types of such units. The main purpose of the pumps is to pump aggressive liquids. These can be all kinds of acids, toxic substances, caustic and abrasive liquids, and liquefied gases.
All of the above aggressive liquids are endowed with such negative qualities as toxicity, explosiveness, tendency to polymerization, uncontrolled temperature, etc. Therefore, chemical equipment for pumping is made from high-strength polymers that are resistant to chemical processes. The central type of mechanisms is the most popular. This type of pumping equipment is produced in various designs. Pumps are divided into:
- cantilever;
- vertical
- vortex;
- submersible;
- monoblock;
- sectional;
- tight;
- horizontal
- multistage.
Sealed centrifugal pumps are used in the chemical industry. Units can pump not only caustic and aggressive environments. The mechanisms are excellent for working in conditions of high pressure, vacuum, low and high temperatures. The flow part of the units must be made of proven materials. The lifetime of the unit depends on their quality. Modern equipped with a flow part made of:
- chrome nickel-molybdenum steel;
- chrome or siliceous 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. A seal is located between the electric motor and the pump part. Equipment has both advantages and disadvantages. The benefits, of course, are greater. It:
- ease of use and adjustment;
- compactness;
- light weight;
- relatively inexpensive price;
- profitability;
- reliability.
Pumps operate quietly, smoothly, which protects the device from sudden hydraulic surges.
The disadvantages include the established restrictions that make it impossible to use the equipment in some production conditions.
The market for chemical aggregates is quite wide. The economic, environmental, and food safety of the state depends on their capacity and quality. Such equipment is used in various fields of life. It:
- chemical production;
- pharmaceutical field;
- paper production;
- Housing and communal services;
- textile industry;
- production of paints and varnishes;
- nuclear power.
