Dosing pumps for demanding industrial needs

A dosing pump is a positive displacement pump, which ensures the same amount of liquid with each pump stroke. Dosing is adjusted either manually or through automation systems.

Choosing the right dosing pump is primarily based on the chemical properties of the pumped liquid, as well as the pressure and accuracy required by the process. Material selection ensures a long pump life cycle in demanding environments. Stainless steel and acid-resistant stainless steel are suitable for hygienic applications and aggressive substances, while plastic materials such as PVC and PVDF provide protection against corrosion.

When choosing the pump type, the solids content and viscosity of the liquid must be considered. A diaphragm dosing pump is a sealed solution for toxic and corrosive substances. A piston dosing pump is best suited for clean liquids and applications requiring working pressures of up to 250 bar. Our specialists help with sizing and selecting the right control method, taking into account the technical requirements of each industrial process.

Dosing pumps offer significant benefits for controlling and optimizing industrial processes. A dosing pump is an essential part of production lines in applications where absolute accuracy and reliability are required.

Accuracy and repeatability in industrial processes

A dosing pump is based on a positive displacement operating principle, which ensures the same precisely measured amount of liquid with each pump stroke. High dosing accuracy is critical in demanding applications in the pharmaceutical and chemical industries. A dosing pump ensures consistent process quality and minimizes the waste of expensive chemicals. A calibrated device repeats the same dose again and again without variation. Consistent dosing ensures that the end product meets strict quality requirements.

Material options and chemical resistance

The equipment is manufactured from several different materials according to the requirements of different operating environments. Material options make it possible to use the pumps with a wide range of liquids. Pumps made from acid-resistant stainless steel are suitable for handling corrosive liquids. Plastic and chemically resistant materials meet the requirements of acidic or alkaline substances. The versatility of the materials meets the hygiene requirements of the food industry and the demands set by aggressive substances in the chemical industry.

Automation and process control

A modern dosing pump can be connected directly to automation systems to improve the efficiency of production processes. Frequency converters and control systems enable remote control of pumps as well as real-time adjustment according to changing process requirements. Automation reduces the need for manual work and saves significant resources. User-friendly interfaces and adjustment mechanisms are designed for expert-level needs.

Durability and life cycle costs

Dosing pumps are designed to withstand demanding industrial conditions and continuous use. The equipment operates reliably at high pressures and across wide temperature ranges with aggressive chemicals. A durable structure reduces the need for maintenance and extends the pump’s technical service life. Low maintenance needs make a dosing pump a financially worthwhile investment in the long term. Piston dosing pumps can reach working pressures of up to 250 bar. Diaphragm dosing pumps provide a sealed solution for liquids that contain solids or are corrosive.

Safety and risk management in industry

Safety is a primary criterion when handling hazardous or toxic substances. Diaphragm dosing pumps and hydraulic diaphragm dosing pumps are designed to prevent liquid leaks into the environment. The sealed structure protects employees and the production environment. Dosing pumps include built-in safety features such as pressure relief valves and automatic alarm systems. Technical solutions prevent damage and ensure process safety in demanding chemical industry applications.

A dosing pump is a positive displacement pump developed for highly accurate and repeatable liquid dosing. Its operation ensures that the same amount of liquid is transferred with each pump stroke.

Dosing pumps are used in industry, agriculture and water treatment for the accurate feeding of chemicals, fertilizers or other additives. Typical applications include pharmaceutical manufacturing, swimming pool water chlorination and industrial washing machines.

Electromagnetic solenoid pumps are suitable for small dosing volumes and precise microprocessor control. Electric motor-driven solutions provide higher flow rates and higher working pressures.

The manufacturing material, such as PVC, PP, PVDF or acid-resistant stainless steel, is always selected based on the chemical resistance and temperature of the pumped liquid.

Dosing can be fully automated using microprocessor technology, frequency converters or mA control signals as part of a wider automation system.

Stepper motor technology offers an exceptionally wide adjustment range and extreme accuracy, even at flow rates as low as 0.001 l/h. The technology makes it possible to maintain accurate dosing even when pumping highly viscous liquids.

A piston dosing pump is an ideal choice for clean liquids in applications that require exceptionally high operating pressure, up to 250 bar.

A water-hydraulic dosing unit operates without electricity, using only water flow and pressure. The device is a proportional dosing unit, and the technology ensures that the amount of additive remains constant in relation to the water flowing through it.
