Dosing Pumps
1 to 2 (from a total of 2)
**Dosing pumps** in the paper industry play an important role in the precise and controlled addition of chemicals and additives at various stages of production. These pumps are designed to deliver small amounts of liquids or chemicals with high accuracy and consistent dosing, which is critical for the quality, efficiency and environmental impact of paper production.
Here are the main functions and applications of **Dosing pumps** in the paper industry:
### 1. **Chemical addition for fiber treatment**
During paper production, various chemicals are used to improve the properties of the pulp or paper pulp. Dosing pumps are used to precisely dose chemicals such as **bleach**, **starch**, **adhesives**, **plasticizers** or **fillers** into the paper pulp.
- **Bleach**: To brighten the pulp and achieve the desired paper color.
- **Starch**: To increase the strength of the paper and improve its structure.
- **Adhesives and plasticizers**: To make the paper supple or to influence its surface properties.
The dosing of these chemicals must be precise to keep the quality of the paper constant and to use resources efficiently.
### 2. **Controlled addition of additives**
In paper production, various **additives** are used, such as **humectants**, **antistatic agents**, **dispersants** or **flocculants**. These substances are added in very small quantities and with high precision to achieve the desired paper properties.
Dosing pumps ensure that the addition of these additives is constant and in the right quantities, without overdosing or underdosing, which optimizes production costs and ensures the quality of the final product.
### 3. **Water and chemical management**
Dosing pumps are also used in the **water treatment process** to precisely dose chemicals for treating wastewater, disinfection or pH adjustment. This helps to comply with environmental regulations and minimize water consumption.
### 4. **Optimizing energy consumption and production costs**
By precisely controlling the addition of chemicals with dosing pumps, paper mills can minimize the use of expensive or environmentally harmful chemicals. This leads to a **reduction in production costs** and an **improvement in energy efficiency**, as unnecessary amounts of chemicals or energy do not have to be used.
### 5. **Controlling paper quality**
The dosing of chemicals and additives is directly linked to paper quality. Dosing pumps ensure a constant and even addition of substances, which leads to **consistent product quality**. This affects, among other things, the paper strength, the surface structure, the whiteness of the paper and the flexibility.
### 6. **Environmental friendliness and sustainability**
The precise use of dosing pumps not only saves resources, but also reduces environmental impact. The precise dosing prevents an overdose of chemicals, which leads to less pollution of the wastewater. As a result, dosing pumps contribute to **sustainable production** and compliance with environmental regulations.
### 7. **Error reduction and process automation**
Dosing pumps are often connected to **automation systems** that allow the dosing process to be continuously and accurately monitored. They can automatically react to certain production parameters, such as the speed of the paper machine or the composition of the paper pulp. This reduces human errors and ensures a more stable and reliable process.
### Conclusion:
**Dosing pumps** in the paper industry are central to the precise and efficient control of the use of chemicals, additives and other liquids throughout the production process. They not only ensure consistently high paper quality, but also reduce waste, costs and environmental impact. Their precise dosing enables precise adjustment of the paper quality and thus contributes to the optimization of the entire paper production.
