Dosing pumps are specialized equipment designed for precise dosing of liquids in various industrial and laboratory processes. Thanks to their ability to handle liquids of different viscosities, chemical composition and temperature, they are indispensable in the pharmaceutical, chemical, food and other industries.

Dosing pumps are classified into three main types depending on the delivery method:

1. Plunger pumps: They provide the highest dosing accuracy and are capable of generating extremely high pressures. This makes them ideal for applications where maximum precision and flow stability are required, such as in the chemical and pharmaceutical industries.
2. Peristaltic pumps: They are ideal for handling viscous liquids and crystallizing substances. Their flexible design allows for efficient handling of shear-sensitive products without the risk of damage.
3. Diaphragm pumps: They are known for their versatility. They can be powered by mechanical action or hydraulic drive, making them suitable for a wide range of applications, including the transportation of aggressive chemicals.

Main areas of application:

1. Pharmaceuticals: Precise dosage of active substances, filling of ampoules, syringes and other containers.
2. Chemical industry: Dosing of reagents, acids, alkalis, and catalytic components.
3. Food industry: Adding flavors, colors, preservatives or other additives to products.
4. Water treatment: Injection of reagents for water purification or conditioning.
5. Cosmetics industry: Filling packages with creams, lotions, gels, or other products.

Features of dosing pumps

1. Accuracy: Ensure product delivery with minimal deviation from the set parameters.
2. Flow control: Easily customizable to change the dose volume according to process requirements.
3. Resistance to chemical attack: The use of materials such as PTFE, EPDM or PVDF ensures durability and safety when working with aggressive media.
4. Possibility of microdosing: They are suitable for working with volumes from microliters to several liters per hour.
5. Ease of maintenance: The modular design allows for quick maintenance.

Dosing pumps for pharmaceuticals

Pharmaceutical metering pumps are highly specialized equipment for precise dosing and filling of small volumes of product. Their design ensures the highest accuracy and compliance with purity standards, which is critical for the pharmaceutical industry.

Features of monoblock piston pumps:

1. Direct injection system: It provides an even flow without pulsations, which guarantees accurate dosing even for the smallest volumes.
2. High-end materials: Contact parts are made exclusively from materials certified for use in the pharmaceutical industry.
3. Hygienic: The pumps can be easily disassembled for sterilization to ensure compliance with GMP standards.

Application:

• Filling ampoules, vials, and syringes.
• Working with biological products, vaccines, and sterile solutions.
• Use in laboratory and small-scale production.

How to choose a dosing pump?

1. Technical parameters: Determine the dosing volume, viscosity, and chemical composition of the liquid.
2. Operating conditions: Take into account the temperature and the presence of abrasive or corrosive components.
3. CIP/SIP compatibility: Make sure the pump supports an automatic cleaning system.
4. Precision and stability: Check the dosing repeatability settings.
5. Construction materials: Choose a pump made of materials that meet your requirements for chemical resistance and hygiene.
