Our standard pump head systems boast a pressure resistance of 4MPa, with certain systems achieving up to 6MPa.
The differential pressure between inlet and outlet surpasses 25bar, contingent upon fluid viscosity.

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: During design, ideally position the pump beneath the tank, secure the motor base with screws, and input medium positive pressure to the pump inlet, especially for viscous media with poor fluidity. Given the micro gear pump's compact form, avoid exerting pressure from piping or instrumentation onto the pump body.

Ensure the inlet pipe is as short as possible, and the inlet pipe should be equipped with a filter to maintain cleanliness and prevent particle contamination.
Pipe diameter requirements: When dealing with viscous media, it's highly advisable that the pipe exceeds the pump inlet size. To ensure optimal performance, adhere to the pipe diameter recommended by our company's advanced selection software. It's crucial to recognize that an undersized inlet may fail to meet the desired flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our pumps come in a variety of materials, ensuring compatibility with a broad spectrum of fluids. Given the vast array of working conditions and chemical compositions, we strongly advise that you test the pump in the circuit under actual operating conditions. If your application involves transporting substances like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, or dimethylacetamide, reach out to us, if a conventional pump head cannot transport these media, we are equipped to design customized solutions tailored to your specific working conditions.

Q: Can the pump be used for metering?
A: Indeed, all our pumps are positive displacement pumps, ideally suited for precise metering applications. While accuracy and repeatability hinge on the pump driver/control system and fluid properties, delivery precision can achieve a remarkable +/-0.5%. For further details, please get in touch with us.

Q: Which motors can be used?
A: We provide a diverse array of drive types, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, to cater to your specific requirements.

Q: How can we decide the input power of the pump?
A: JONSN offers precise calculations for the requisite input power based on your working requirements and the distinct characteristics of your fluid.


Q: What is the noise value of the pump?
A: The noise levels are contingent upon pump installation, motor speed, and fluid type. Typically, the gear pump emits a reference noise level of 55 dB at 1 meter when operating at a pressure difference of 3 bar and a speed of 3000 rpm.

Q: Can liquids containing solid particles be transported?
A: Our gear pumps are not designed to transport media containing particles.

Q: Can the pump be reversed?
A: Ideally, the direction of the arrow, marked at the factory, indicates the standard flow direction. However, our pumps are versatile and can operate effectively in both directions.

Q: Can the pump run dry?
A: Our gears and bushings, crafted from PEEK modified and post-treated materials, boast exceptional dry wear resistance. We invite you to view our dry run test video. Nonetheless, it is advisable to minimize dry running to extend the pump's longevity.

Q: Is the pump self-priming?
A: Absolutely, for more detailed information, please refer to our comprehensive datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads are engineered to function efficiently within a temperature range of -20 to 80°C. Please consult us if the temperature exceeds 80°C or varies significantly, as factors such as magnets, clearances, and motor bearings must be taken into account.

Q: How does viscosity affect gear pump and system performance?
A: When it comes to viscous materials, they can notably enhance the volumetric efficiency of the pump while minimizing the likelihood of leakage in the gear pump. However, caution is advised: the speed must be reduced in accordance with the viscosity to ward off potential overloading. In contrast, low-viscosity fluids tend to result in increased internal leakage. As the outlet pressure rises, so does the internal leakage, leading to a decrease in volumetric efficiency. Under constant conditions of pressure, speed, and medium temperature, the internal leakage rate stabilizes, maintaining a steady, linear flow rate. Please consult factory for more intricate details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: Rest assured, the gear pump will seamlessly handle a gas/liquid mixture. However, you might notice an increase in noise levels when gas is transmitted. Additionally, there might be a fleeting alteration in the load on the pump, manifesting as fluctuations in the outlet pressure and the power used by the motor.

Q: What are the minimum and maximum speeds allowed?
A: The maximum speed is meticulously detailed in the data sheet for each model, based on a water medium. as For viscous fluids, a thoughtful reduction in the maximum speed is essential. The minimum speed is primarily influenced by the motor's starting speed control, the flow rate, and the factors contributing to internal leakage.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, pumps are offered with materials that comply with FDA standards.

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

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

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump's load and the motor's torque capacity exceed the magnetic coupling's torque capacity, causing the magnetic drive pump to decouple, resulting in noise. Upon decoupling, it's crucial to halt the motor immediately for troubleshooting.

Q: How do we adjust flow rate?
A: In positive displacement pumps, adjusting the flow rate is conveniently achieved by modifying the motor speed. There exists an almost direct linear correlation between speed and flow.

Q: What is the starting capacity of the micro gear pump?
A: Starting capacity is variable across different pumps and is contingent upon multiple factors, including fluid viscosity, line size, steam pressure, speed, and whether the pump is operational in wet or dry conditions.

Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to a scenario where a portion of the fluid on the pressure side recirculates back to the inlet through the gear gap, impacting efficiency. It's a typical challenge for all gear pumps. Precision micro gear pumps experience relatively lower internal leakage, and low-viscosity fluids can navigate these minimal gaps more effortlessly, making the pump particularly efficient with thicker or more viscous fluids.

Q: What is cavitation?
A: Cavitation refers to the formation of vapor cavities ('bubbles' or 'voids') within the liquid, a consequence of the inlet pipe diameter being insufficient for the pump's flow rate. These cavities emerge due to the fluid dynamics and physical attributes of the pump system, such as available pressure, temperature, and pump speed. Cavitation is often accompanied by noise and can lead to premature wear of the pump.

Q: How do I identify Jonsn pump?
A: Distinguishing our pump is simplified with the presence of our distinct LOGO and a precise laser code engraved on the end face. Each unit is meticulously marked with the manufacturing date, a unique product code, and an individual serial number (S/N). For a comprehensive trace of its origins and authenticity, the original configuration sheet and detailed test records are accessible via the S/N code.
