The miniature magnetic drive metering pump, a type of gear metering pump, utilizes the principle of magnetic coupling for power transmission instead of traditional coupler connections. This design prevents direct contact between the liquid and the drive mechanism, achieving superior sealing performance.
The flow rate of the miniature magnetic drive metering pump is controlled by the rotational speed of the motor. It can be equipped with various motors such as brushless DC motors, variable frequency motors, stepper motors, and servo motors. Different motors are selected based on the medium being pumped and the specific operating conditions.
Our company's CX series of magnetic drive pumps cater to the majority of market demands. They are primarily used for transferring low to medium viscosity fluids in industries such as chemical processing, pharmaceuticals, food and beverage, printing and dyeing, and laboratories. These pumps are particularly suitable for applications involving mildly corrosive media and scenarios that require a high degree of sealing reliability.
Magnetic Drive Gear Pump is a positive displacement gear pump that utilizes a magnetic drive to achieve non-contact torque transmission, replacing dynamic seals with static seals and resulting in a completely leak-free operation. It is ideally suited for industries such as petroleum, chemical, pharmaceutical, smelting, electroplating, environmental protection, food, and national defense. This pump is an excellent choice for handling flammable, explosive, volatile, toxic, rare, valuable, and various corrosive liquids.
It is suitable for transferring fluids with certain lubricity and free of solid particles or fibers in various industrial processes. For applications involving corrosive media or requiring high hygienic standards, stainless steel construction is available.
The CX series of magnetic drive gear pumps includes three types: MKCB (involute tooth), MYCB (circular arc tooth), and MNCB (cycloidal tooth). Their different structural configurations make them suitable for handling media of various properties and viscosities.
The gear pump is a rotary positive displacement pump that transports fluids or increases their pressure by changing and moving the working volume formed between the pump housing and the meshing gears. It consists of two gears, a pump housing, and front and rear covers, which together form two enclosed chambers. When the gears rotate, the volume on the disengaging side increases, creating a vacuum that draws liquid in. Conversely, the volume on the engaging side decreases, forcing the liquid into the discharge pipeline. The meshing line of the two gears separates the suction and discharge chambers. The discharge pressure of the gear pump depends entirely on the resistance at the pump outlet.
Jiushi Precision Miniature Magnetic Drive Gear Pumps are suitable for handling: deionized water, methanol, urea solution, kerosene, additives, agents, lubricating oil, alkali solutions, ammonia solutions, cobalt solutions, dialysate, ethylene glycol, Freon, ink, glycerol, phenolic resin, curing agents, essential oils and fragrances, and fluorinated fluid pumping systems.
A miniature magnetic drive metering pump operates based on the principle of magnetic coupling. The motor rotates an external drive magnet assembly, which generates a rotating magnetic field. This field penetrates the containment shell (or barrier) and drives an internal magnet assembly connected to the pump's gears. This process converts the motor's rotary motion into a precise, recurring volumetric displacement of fluid. Crucially, the physical barrier (hermetically sealed chamber) completely separates the pumped fluid from the drive components and the external environment, eliminating the need for a traditional dynamic shaft seal.
Magnetic drive gear pumps are particularly ideal for applications requiring small flow rates, pulse-free flow, high linearity, high pressure differentials, leak-free operation, precise metering, and stable fluid transfer. Typical use cases include:
Automation and process control systems
Micro-dosing systems
Recirculation and boost systems
Automatic feeding (dosing) systems
Waste heat recovery systems
Sampling equipment (including vacuum suction)
Chip processing equipment
Laboratory equipment
Cooling systems (refrigerant circulation pumps)
Foundry machinery
Packaging machinery
Cleaning systems
Additive dispensing systems
Chemical metering systems
Pilot and semi-pilot plants
The magnetic drive gear pump offers the following key advantages:
**1. Pulse-Free, Linear, and Precise Transfer**
As a positive displacement pump, it utilizes gears to provide consistent and stable fluid delivery. When paired with a servo or stepper motor, it achieves extremely high precision in flow transfer.
**2. High Inlet Vacuum and Pressure Differential**
With an inlet vacuum capacity of -0.095 MPa, it is capable of medium-to-high pressure transfer of low-viscosity fluids.
**3. Leak-Free Design**
The magnetic drive coupling and static O-ring seals ensure complete isolation of the pumped medium from the external environment.
**4. Excellent Craftsmanship and Modular Design**
Gear shafts are made of specially modified PEEK material, undergo heat treatment, and are combined with high-strength zirconia ceramic.
Sliding bearings are manufactured using a specially modified PEEK composite with nano-ceramic formula and specialized molding processes.
Test results show that even after 2 hours of dry running under extreme conditions, the pump maintains highly linear flow performance.
Adopting the lean production concept, advanced processing equipment, and exquisite workmanship, it is an external gear pump designed and manufactured specifically for high-end applications.

| Q1.What is the working principle of a magnetic gear metering pump? |
| A1.A magnetic gear pump uses a magnetic coupling to transmit power, and gears engage to deliver liquid in a precise volume. The design eliminates mechanical seals, preventing leakage, making it ideal for corrosive, toxic, volatile, or valuable liquids. |
| Q2.What kinds of liquids can the pump handle? |
| A2.It is suitable for low to medium viscosity liquids, such as organic solvents, acids and alkalis, fuel oils, lubricants, flavors, vegetable oils, and pharmaceuticals. ⚠️ Not recommended for media with large particles or strong abrasiveness. |
| Q3.Does the pump leak? |
| A3.No. The magnetic drive design ensures a fully sealed system, eliminating leakage caused by seal wear. |
| Q4.How is the dosing accuracy ensured? |
| A4:Being a positive displacement pump, the flow rate is proportional to the speed. With frequency converters, accuracy can reach ±0.5%. |
| Q5.What is the difference between a magnetic gear metering pump and a regular magnetic pump? |
| A5.A regular magnetic pump is used for large flows without strict precision requirements. Magnetic gear metering pumps are designed for small flow, high-precision dosing, with stable and low-pulsation output. |
| Q6.Can it handle high viscosity liquids? |
| A6.It can handle fluids within 0.3–2000 cP viscosity. For very high viscosities, efficiency drops, so heating or special high-viscosity pumps are recommended. |
| Q7.How to prevent dry running? |
| A7.Ensure the pump is primed before startup; install level switches or dry-run protection; always check the chamber is filled after long shutdowns. |
| Q8.What is the flow and pressure range? |
| A8.Flow range: 0.1 L/min ~ 500 L/min (depending on model). Pressure range: 0.1 ~ 2.5 MPa. |
| Q9.How to maintain the pump? |
| A9.Inspect gears and bearings regularly; keep liquids clean to avoid particles; prevent dry friction; replace wear parts (bearings, bushings) periodically. |
| Q10.Can the pump run in reverse? |
| A10.Theoretically yes, but long-term reverse running reduces accuracy and causes wear. For bidirectional transfer, use special models. |
| Q11.What are common problems and solutions? |
| A11.• Low flow: Check for air ingress, blockages, or high viscosity • Excessive noise: Gear wear or air bubbles in pump chamber • Overheating: Dry running, magnetic coupling slip, or high viscosity • Low pressure: Leakage in outlet line or worn gears |
| Q12.What is the service life? |
| A12.Typically 3–5 years or longer under normal conditions, depending on liquid properties, operation frequency, and maintenance. |
