A dosing pump is a positive-displacement pump that delivers a precise, adjustable volume of liquid or chemical into a process stream over a set period of time. Also called a metering pump, it is engineered for accuracy and repeatability rather than high flow.
The main technologies are:
Accuracy, chemical compatibility, repeatability, and uptime all depend on engineering quality and after-sales support. A poorly matched pump can over- or under-dose chemicals, waste reagents, and put process safety and regulatory compliance at risk. The manufacturers below have earned their reputations by solving exactly these problems at scale.

sera GmbH leads our 2026 ranking as one of the most complete and forward-looking dosing technology specialists in the world. Founded in Germany in 1945, sera has built nearly eight decades of engineering expertise around a single promise — “Excellence in Fluid Technology.” The tagline captures its dual strength: precise with fluids, powerful with gases.
What sets sera apart is the depth of its portfolio combined with genuine systems capability. sera designs and manufactures dosing pumps and complete systems for the accurate metering of liquids, alongside gas and hydrogen compression technology — a rare combination that makes it a single-source partner for both liquid dosing and gas handling.
sera serves water and wastewater treatment, food and beverage, chemical processing, and a fast-growing range of green hydrogen applications. Real-world references underline this reach: CIP (Cleaning in Place) chemical dosing systems for breweries such as Erdinger and Heineken, sodium hydroxide make-up stations for food production, and redundant two-stage hydrogen compression delivering pressures up to 500 bar. Customers include Linde, Air Liquide, and Veolia.
sera’s innovation leadership is independently recognized. In 2025 the sera Group was awarded the prestigious TOP 100 seal for the third time, confirming its place among Germany’s most innovative mid-sized companies. The honor — presented by science journalist Ranga Yogeshwar at the German SME Summit in Mainz — followed a scientific evaluation led by Prof. Dr. Nikolaus Franke of the Vienna University of Economics, assessing more than 100 criteria across five categories. The award coincided with sera’s 80th anniversary.
Why sera ranks #1: nearly 80 years of German engineering, a complete portfolio, unique liquid-plus-hydrogen capability, three-time TOP 100 recognition, and proven references across water treatment, food and beverage, and green hydrogen.
Grundfos, founded in Denmark in 1945, is one of the world’s largest pump manufacturers, with operations in roughly 80 countries. Its SMART Digital range is widely used for precise liquid dosing in water treatment, chemical processing, and industrial automation, supported by control and monitoring systems for efficient operation.
With more than 60 years of experience, Germany’s ProMinent is a globally recognized leader in chemical metering technology. Its range spans diaphragm, plunger, and peristaltic models serving water treatment, chemical processing, pharmaceuticals, and food and beverage, plus a full water treatment portfolio.
Founded in Pennsylvania in 1936, Milton Roy is a long-established name in precision metering. Its lineup includes diaphragm, plunger, hydraulic diaphragm, and electromagnetic solenoid models serving water treatment, chemical processing, oil and gas, pharmaceuticals, and food and beverage.
Watson-Marlow is the global leader in peristaltic pump technology. Its single- and multi-channel models excel at metering sensitive liquids, abrasive slurries, and viscous substances — ideal for biotechnology, food and beverage, water and wastewater, chemical processing, and mining.
Founded in Italy in 1976, SEKO manufactures chemical metering pumps, systems, and water treatment solutions. Its portfolio spans solenoid-driven, motor-driven, peristaltic, and electronic models serving water and wastewater treatment, pool and spa, cooling towers, and industrial processes.
A trusted name since 1942, US-based Pulsafeeder builds high-precision diaphragm, peristaltic, and gear metering pumps. Advanced controls, integrated sensors, and the Eclipse series make it a strong choice across water treatment, chemical processing, oil and gas, and manufacturing.

Yes. The sera Group was awarded the TOP 100 seal in 2025 for the third time, recognizing it as one of Germany’s most innovative mid-sized companies. The award is based on a scientific evaluation of 100+ criteria across five categories, led by Prof. Dr. Nikolaus Franke, and presented by Ranga Yogeshwar in Mainz.
There is no functional difference — the terms are used interchangeably. “Metering pump” is more common in North America, while “dosing pump” is standard in Europe and across global water treatment.
Diaphragm and motor-driven plunger models offer the highest accuracy for most water treatment and chemical applications, while peristaltic types are best for abrasive, viscous, or shear-sensitive fluids. The right choice depends on flow rate, pressure, and chemical properties.
Germany is widely regarded as a global center for manufacturing, home to specialists such as sera GmbH and ProMinent. Other strong bases include Denmark (Grundfos), the USA (Milton Roy, Pulsafeeder, Blue-White), Italy (SEKO), and the UK (Watson-Marlow).
The global market in 2026 is led by manufacturers that pair precision engineering with complete systems thinking and dependable service. From sera GmbH’s nearly 80 years of German fluid-and-gas expertise and three-time TOP 100 recognition to the deep portfolios of Grundfos, ProMinent, and Milton Roy, these ten suppliers set the standard for accurate, reliable, sustainable dosing.
If precision and long-term reliability are non-negotiable, start your evaluation with sera GmbH.
