A: Our conventional pump heads withstand temperatures from -20°C to 80°C, with customization options extending from a frosty -60°C to a scorching 160°C.
Standard pump head systems endure pressures up to 4MPa, with advanced systems reaching an impressive resistance of 6MPa.
The difference in pressure between inlet and outlet surpasses 25 bar, tailored to varying viscosities.

Q: What factors should be considered in the installation of the pump? What should be considered when designing the piping system of the pump?
A: For optimal performance, the pump should be placed beneath the tank, securely fastening the motor base with screws. Ensure positive pressure feed to the pump inlet, particularly for viscous mediums with low fluidity. Due to the compact design of the micro gear pump, take care not to exert pressure on the pump body with piping or instruments.

Keep the inlet pipe as short as feasible, and ensure it is equipped with a filter to maintain a clean, particle-free flow.
Pipe Diameter Requirements: To ensure optimal performance when conveying viscous media, it's recommended that pipes be larger than the pump's inlet size. Adhere to the pipe diameter recommendations provided by our selection software. Sometimes, an undersized inlet may not fulfill the requisite flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our pumps come in various materials, making it easy to find a compatible option for most fluids. Given the wide variety of working conditions and fluids, we strongly advise testing the pump within the actual circuit conditions. If your material includes dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or other challenging media, please reach out to us, if a conventional pump head cannot transport these media, we can offer tailored solutions based on specific working conditions.

Q: Can the pump be used for metering?
A: All our pumps are designed as positive displacement pumps, ideal for precise metering applications. The accuracy and repeatability depend on the pump's driver/control system and the fluid's nature, achieving a delivery precision of +/-0.5%. Contact us for further details.

Q: Which motors can be used?
A: We provide a diverse range of drive options including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and even Air Motor.

Q: How can we decide the input power of the pump?
A: JONSN will expertly calculate the required input power based on your working conditions and fluid characteristics.


Q: What is the noise value of the pump?
A: Pump noise levels vary with installation, motor speed, and fluid type. Typically, our gear pumps exhibit a noise level of 55 dB at 1 meter with a pressure difference of 3 bar and a speed of 3000 rpm.

Q: Can liquids containing solid particles be transported?
A: Gear pumps are not suited for transporting media with solid particles.

Q: Can the pump be reversed?
A: While the standard flow direction is marked with an arrow at the factory, the pump can operate in both directions.

Q: Can the pump run dry?
A: Our PEEK-modified and post-treated gears and bushings have enhanced resistance to dry wear. We offer a dry run test video for reference. However, dry running should be minimized to extend pump life.

Q: Is the pump self-priming?
A: Indeed, please consult our datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads function efficiently within a temperature range of -20 ~ 80°C. Please reach out to us if temperatures exceed 80°C, as factors like magnets, clearances, and motor bearings may need special consideration.

Q: How does viscosity affect gear pump and system performance?
A: When dealing with viscous materials, they can significantly enhance the volumetric efficiency of the pump while minimizing gear pump leakage. However, it is crucial to adjust the speed according to the viscosity to prevent overloading. On the other hand, low-viscosity fluids tend to result in increased internal leakage. As outlet pressure rises, so does internal leakage, leading to decreased volumetric efficiency. When pressure, speed, and medium temperature remain constant, expect a stable internal leakage rate, maintaining a linear flow rate relationship. Please consult factory for details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: A gas/liquid mixture can flow through the pump seamlessly. You might notice an increase in noise when gas is present. Additionally, there will be temporary changes in the pump's load, observable through fluctuations in outlet pressure and motor power consumption.

Q: What are the minimum and maximum speeds allowed?
A: Each model's data sheet outlines the maximum speed, calculated based on a water as medium. When dealing with viscous fluids, the maximum speed should be reduced. Minimum speed considerations primarily involve motor starting speed control, flow rate, and internal leakage factors.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, pumps are available with FDA-compliant materials, ensuring safety and reliability.

Q: What is the recommended filtering level?
A: For optimal performance, it is recommended to use a 25-micron filter at the pump's inlet. Ensure the filter has a large enough surface area to prevent pressure drops and safeguard the pump's internal components.

Q: What affects pump and motor life?
A: Several factors have an impact on service life. Key elements to assess include the frequency of on/off cycles, operating speed, load (pressure), and the level of fluid contamination.

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump load and motor torque capacity exceed the magnetic coupling's torque capacity, causing the magnetic drive pump to decouple and become noisy. Immediate motor shutdown for troubleshooting is necessary when decoupling happens.

Q: How do we adjust flow rate?
A: For positive displacement pumps, adjusting flow is straightforward by modifying motor speed. There exists an almost linear relationship between speed and flow, allowing precise control.

Q: What is the starting capacity of the micro gear pump?
A: Starting capability varies depending on the pump and is influenced by factors such as fluid viscosity, line size, steam pressure, speed, and whether the pump operates wet or dry.

Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to the phenomenon where some fluid on the pressure side leaks back to the inlet side through gear gaps, impacting efficiency. Though common in all gear pumps, precision micro gear pumps exhibit smaller internal leakages. Low-viscosity fluids may easily pass through these small gaps, enhancing efficiency in thicker or more viscous fluids.

Q: What is cavitation?
A: Cavitation is the formation of vapor cavities ('bubbles' or 'voids') within the liquid, typically due to the inlet pipe diameter being smaller than the pump's flow rate. It results from the fluid and physical properties of the pump system, including available pressure, temperature, and pump speed. Cavitation is often accompanied by noise and can lead to premature pump wear.

Q: How can I easily identify Jonsn pump units?
A: Each pump is distinctly marked with a LOGO and a precise laser code on its end face. This includes critical details such as the date of manufacture, the unique product code, and the specific serial number (S/N). By utilizing the S/N code, one can seamlessly trace back to the original configuration sheet and comprehensive test records.
