Chemical pumps are energy-saving pumps jointly designed by the whole country. The performance and technical requirements of pumps are designed according to the performance and size specified in the international standard ISO2858. They can be divided into stainless steel chemical pumps, plastic chemical pumps, fluoroplastic chemical pumps, electric chemical pumps, and pneumatic chemical pumps.

advantage

The advantages of chemical pumps include a reasonable layout of hydraulic performance across the entire series, a wide range of user choices, a "rear opening" structure, easy maintenance, and superior efficiency and suction capacity.

purpose

Widely used for industrial and urban water supply and drainage, and can also be used for irrigation and drainage in farmland and orchards, for transporting clean water or other liquids with physical and chemical properties similar to clean water.

Classification

1、 According to the different materials of chemical pumps, their application fields are classified as follows:

1) Chemical pumps (made of stainless steel) are widely used in industries such as petroleum, chemical, metallurgical, synthetic fiber, food, and synthetic fiber to transport alkaline corrosive media;

2) Chemical pumps (made of fluoroplastic material) are used to transport any acidic, alkaline or corrosive medium;

3) Chemical pumps (made of cast iron material) are used for industrial and urban water supply and drainage, as well as for irrigation and drainage in farmland and orchards, to transport clean water or other liquids with physical and chemical properties similar to clean water.

2、 Classification and detailed introduction of chemical pumps based on their different uses:

1) Process pumps: including feed pumps, reflux pumps, circulation pumps, flushing pumps, sewage pumps, supplementary pumps, output pumps, etc.

2) Utility pumps: including boiler pumps, cooling tower pumps, fire pumps, deep well pumps for water sources, etc.

3) Auxiliary pumps: including lubricating oil pumps, sealing oil pumps, hydraulic transmission pumps, etc.

4) Pipeline conveying pumps: pumps used for oil pipelines, pumps used for loading and unloading vehicles, etc.

3、 Classified by working principle and structure:

1) Vane pump: By rotating the pump shaft, various impeller blades are driven to apply centrifugal or axial force to the liquid, conveying it to pipelines or containers, such as centrifugal pumps, vortex pumps, mixed flow pumps, and axial flow pumps.

2) Positive displacement pump: a pump that uses continuous changes in the volume of the pump cylinder to transport liquids, such as reciprocating pumps, piston pumps, gear pumps, and screw pumps.

3) Other forms of pumps: there are electromagnetic pumps that use electromagnetic transportation to transport liquid conductive materials; Pumps that utilize fluid energy to transport liquids, such as jet pumps, air lifters, etc.

4、 Classified by conveying medium:

1) Water pumps: including clean water pumps, boiler feed water pumps, condensate pumps, and hot water pumps.

2) Corrosion resistant pumps: including stainless steel pumps, high silicon cast iron pumps, ceramic acid resistant pumps, impermeable graphite pumps, hard rubber lined pumps, rigid polyvinyl chloride pumps, shielded pumps, diaphragm pumps, titanium pumps, etc.

3) Impurity pumps: including slurry pumps, sand pumps, sewage pumps, coal powder pumps, ash pumps, etc.

4) Oil pumps: cold oil pump, hot oil pump, submersible pump, slurry pump, liquid hydrocarbon pump, etc.

5、 Classified by usage conditions:

1) High flow and micro flow pumps: flow rates of 300m ³/min and 0.1L/min respectively;

2) High temperature pump and low-temperature pump: high temperature up to 500 ℃, low temperature up to Z53 ℃;

3) High pressure pump and low-pressure pump: high pressure up to 200MPa, vacuum degree of 2.66-10.66kPa (20-80mmHg);

4) High speed pump and low-speed pump: High speed up to 24000r/min, low-speed 5-10 r/min;

5) Metering pump: The flow measurement accuracy reaches ± 0.3%;

6) High viscosity pump: viscosity up to thousands of pascals per second (Pa · s)
