Dosing Pumps for Microdosing and Continuous Flow Applications
Dosing pumps are essential devices for the precise and controlled dispensing of liquids, used across numerous industrial, scientific, and medical sectors. Techma GPM offers a complete range of solutions for micro-dosing and continuous dosing, designed to ensure maximum precision, repeatability, and reliability even at minimal flow rates in the order of µl/min.
The continuous evolution of technology has made it necessary to dispense increasingly smaller quantities of liquids, requiring miniaturized components, precisely controllable motors, and systems adaptable to the specific needs of each application.
Discrete dosing and continuous dosing: what’s the difference
When it comes to liquid dispensing, it is essential to distinguish between discrete dosing and continuous dosing, as this difference determines the choice of the most suitable technology.
- Discrete dosing: release of defined quantities (pulses or cycles), typical in laboratory, analytical, and medical applications.
- Continuous dosing: constant and adjustable flow over time, used in industrial processes, cooling, and automated systems.
For example, for continuous dosing, gear pumps are often the preferred choice, while other technologies may be more suitable for intermittent applications.
Types of pumps for dosing and micro-dosing
How to choose the right dosing pump
The choice of pump depends on a few key parameters:
- Required flow rate (from µl/min to l/min)
- Fluid type (viscous, aggressive, sterile)
- Dosing mode (discrete or continuous)
- Required precision
- System integration (OEM, laboratory, plant)
Based on these factors, the most suitable technology can be identified.
Peristaltic Micro Pumps – Verderflex
Peristaltic micro pumps by Verderflex are ideal for dispensing sensitive and sterile liquids, thanks to their operating principle that prevents contact between the fluid and mechanical parts.
- Flow rates from a few ml/min
- Accurate flow control
- Zero contamination
Ideal when contamination must be avoided or sensitive fluids need to be handled.
Gear Micro Pumps – Micropump
Micropump pumps represent the ideal solution for continuous and precise pulse-free dosing, even with viscous or sensitive liquids.
- Constant and adjustable flow
- Magnetic drive technology with no leakage
- Compatibility with brushless motors
Ideal for continuous dosing and industrial applications requiring stability.
Annular Gear Micro Pumps – HNPM
HNPM pumps are designed for extremely precise micro-dosing even under critical conditions.
- Precision down to µl/min
- Minimal pulsation
- Compatibility with complex fluids
Ideal for extreme micro-dosing and high-precision applications.
Micro pumps and high-precision dosing
When dosing requires extremely small quantities, micro pumps come into play, designed to ensure precision, stability, and control even at minimal flow rates.
- Management of flow rates in the order of µl/min
- High dosing repeatability
- Integration into OEM systems and analytical instrumentation
These solutions are used in laboratories, medical devices, microfluidics, and advanced industrial systems.
