Dosing Pumps for Microdosing and Continuous Flow Applications
Dosing pumps are essential devices for the precise and controlled delivery of liquids, used in a wide range of industrial, scientific, and medical sectors. Techma GPM offers a complete range of solutions for microdosing and continuous dosing, designed to ensure maximum precision, repeatability, and reliability—even at flow rates as low as µl/min.
The constant evolution of technology has made it necessary to dose increasingly smaller volumes of liquid, requiring the use of miniaturized components, precisely controlled motors, and adaptable systems tailored to each application.
Types of Micro Pumps
Peristaltic Micro Pumps – Verderflex
Verderflex peristaltic micro pumps are ideal for dosing sensitive and sterile liquids. Their peristaltic operating principle prevents any direct contact between the fluid and mechanical components. Key features include:
- Flow rates ranging from a few ml/min to higher values
- Precise control of flow and pressure
- Fast and contamination-free liquid changeover
Although pulsation is an inherent characteristic of this pump type, it can be minimized by increasing the number of rollers. These pumps are ideal for applications requiring simplicity, cleanliness, and quick maintenance.

Magnetic Drive Gear Micro Pumps – Micropump
Micropump gear pumps are the optimal solution when a compact, leak-free, and robust micro pump is required. Featuring magnetic drive technology and suction shoe design, they offer:
- High reliability and long service life
- Wide flow rate range (from a few to several hundred ml/min)
- Compatibility with brushless and Atex-certified motors
They are suitable for systems requiring high pressure and continuous dosing, with a compact footprint thanks to the canned motor design.

External Gear Micro Pumps – HNPM
HNPM micro annular gear pumps are designed for extreme conditions, offering highly accurate dosing with virtually pulsation-free flow. Their advantages include:
- Stable and repeatable dosing even with aggressive or viscous fluids
- Digital or analog motor control
- Available with FDA and Atex certifications
- Full technical consulting for hydraulic system design
Applications include laboratories, chemical processing, and mechanical engineering.

How Dosing Pumps Work
Dosing pumps operate based on different principles:
- Diaphragm Pumps: Use a flexible membrane to dose fluids precisely, isolating the fluid from mechanical parts.
- Peristaltic Pumps: Compress a flexible tube with rotating rollers to move the fluid.
- Gear Pumps: Use finely toothed rotors to transfer fluids in a continuous, linear manner.

→ What is a dosing pump?
A dosing pump is a device designed to accurately dose controlled volumes of liquids. It is essential in industries where even small deviations can compromise the process, such as chemical, medical, and environmental fields.
→ Does Techma GPM provide technical support for pump selection?
Yes, Techma GPM offers comprehensive consulting to help clients choose the most suitable dosing pump. We also assist with hydraulic system design and selecting accessory components (motors, valves, filters, etc.).
→ What’s the difference between a peristaltic pump and a gear pump?
Peristaltic pumps move fluid by compressing a flexible tube with rollers, making them ideal for sterile or sensitive liquids. Gear pumps use toothed rotors to transfer fluid, offering a more consistent flow, even with viscous or high-pressure applications.
→ Can dosing pumps operate at very low flow rates?
Absolutely. Techma GPM offers micro pumps capable of handling flow rates down to a few µl/min, with high precision and repeatability at minimal volumes.
→ Are Atex or FDA-certified versions available?
Yes. Several pump models are available with Atex certification for explosive environments and with FDA-compliant wetted materials, ideal for food and pharmaceutical applications.
