Metering Gear Pump for Precision Fluid Transfer

The measurement function of micro magnetic gear pumps involves the precise control and transfer of minute liquid volumes, ensuring highly consistent fluid delivery with each cycle. The gear pump operates through two tightly meshed gears (driving and driven) rotating within a pump chamber, creating sealed cavities that displace fluid with high accuracy. This precision is critical for applications requiring strict proportional dosing.

Our gear pump series covers a flow range of 0-65 L/min. Depending on operating conditions and the characteristics of the conveyed fluid, the pump body can withstand pressures of 20-300 Bar.

All gear pumps deliver smooth, pulsation-free, and precise positive displacement pumping across a broad temperature range (-120 to 150°C) and viscosity range (0.2 to 20,000 cps).

Metering Gear Pump for Accurate Liquid Dosing

A Metering Gear Pump is designed for applications that require accurate liquid dosing, stable flow output and repeatable precision fluid transfer. By using a positive displacement gear structure, the pump can deliver a fixed volume of liquid with each rotation, making it suitable for systems where consistent metering accuracy is required.

Suofu Micro Magnetic Gear Pump solutions are widely used as gear dosing pumps for precision fluid measurement, chemical dosing, reagent delivery, laboratory testing and industrial fluid control. The stable and pulsation-free flow helps improve dosing accuracy and reduce liquid transfer variation in continuous or intermittent operation.

Typical Application Scenarios of Metering Gear Pump:

✅ Pharmaceuticals & Medical: Precise dispensing of pharmaceuticals and nutritional solutions.

✅ Chemical Production: Accurate addition of chemical additives or catalysts.

✅ Laboratory Research: Reagent addition and sample preparation for experiments.

✅ Food & Beverage: Precision ingredient and flavorant dosing.

Why Use a Gear Dosing Pump for Precision Fluid Measurement?

A Gear Dosing Pump provides accurate and repeatable liquid delivery by controlling pump speed and gear displacement. Compared with general transfer pumps, a Metering Gear Pump is more suitable for applications that require fixed-volume dosing, proportional liquid addition and continuous precision fluid measurement.

For chemical additives, catalysts, reagents, nutritional solutions, flavorings or special industrial liquids, the gear dosing pump can provide stable flow output and better process control. This makes the Micro Magnetic Gear Pump a reliable choice for customers who need high metering accuracy, compact structure and long-term stable operation.

FAQ About Metering Gear Pump

What is a Metering Gear Pump?

A precision gear metering pump is a positive displacement pump used for accurate liquid dosing and precision fluid transfer. It delivers liquid through rotating gears and provides stable flow output for metering applications.

What is the difference between a gear dosing pump and a general transfer pump?

A gear dosing pump focuses on accurate and repeatable liquid delivery, while a general transfer pump is mainly used for moving liquid in larger volumes. For precision fluid measurement, a Metering Gear Pump is usually more suitable.

What liquids can a Micro Magnetic Gear Pump handle?

A Micro Magnetic Gear Pump can be used for many low-viscosity and medium-viscosity liquids, including reagents, additives, chemicals, nutritional solutions, flavorings and industrial fluids. The final selection should be based on viscosity, temperature, pressure and material compatibility.
