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 design, install the pump beneath the tank, securing the motor base with screws. Ensure positive pressure delivery of the medium to the pump inlet, particularly for viscous mediums with limited fluidity. Given the micro gear pump's compact size, prevent piping or instrumentation from exerting pressure on the pump body.

Keep the inlet pipe as short as possible, and equip it with a filter to maintain cleanliness and particle-free operation. should be equipped with a filter to ensure the pipeline remains pristine and free from contaminants.
Pipe diameter requirements: When it comes to conveying viscous media, it's crucial that the pipe diameter exceeds the pump inlet size. To ensure optimal performance, please adhere to the pipe diameter guidelines provided by our company's specialized selection software. In some instances, an inlet that is too small might not suffice for the desired flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our versatile pumps are crafted from a variety of materials, ensuring compatibility with a broad spectrum of fluids. Given the vast diversity of working conditions and fluids, we strongly advise testing the pump under actual operating conditions. If the material you handle includes dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, and other challenging media, please reach out to us, if conventional pump head cannot transport this media, we can offer tailored solutions to suit your specific working conditions.

Q: Can the pump be used for metering?
A: Every pump we offer is a positive displacement pump, ideal for precise metering applications. The accuracy and repeatability hinge on the pump driver/control system and the fluid properties, with delivery precision reaching +/-0.5%. For more in-depth information, feel free to contact us.

A: We provide a diverse array of drive options, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor.

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


Q: What is the noise value of the pump?
A: Noise levels are contingent on pump installation, motor speed, and fluid type. Our gear pump offers a reference noise level of 55 dB at a distance of 1 meter when operating under a pressure difference of 3 bar and a speed of 3000 rpm.

Q: Can liquids containing solid particles be transported?
A: Unfortunately, gear pumps are not suitable for transporting media with solid particles.

Q: Can the pump be reversed?
A: Ideally, the factory marks the standard flow direction with an arrow. However, our pumps can operate efficiently in both directions.

Q: Can the pump run dry?
A: Our innovative gears and bushings are constructed from PEEK, modified and post-treated to resist dry wear effectively. You can watch our dry run test video for more insights. Nevertheless, it's best to minimize dry running to extend the pump's lifespan.

Q: Is the pump self-priming?
A: Yes, please refer to our comprehensive datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads operate seamlessly at temperatures ranging from -20 to 80°C. Please consult us if the temperature exceeds 80°C or reaches other extremes, as factors like magnets, clearances, and motor bearings must be considered.

Q: How does viscosity affect gear pump and system performance?
A: Viscous materials can significantly enhance the volumetric efficiency of our gear pumps while minimizing leakage. However, it is crucial to adjust the speed depending on the viscosity to avoid overloading the system. For fluids with low viscosity, internal leakage tends to increase. Additionally, as the outlet pressure rises, so does internal leakage, which inversely affects volumetric efficiency. With constant pressure, speed, and temperature, the internal leakage rate stays consistent, ensuring a steady linear flow relationship. Please consult factory for comprehensive details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: When a gas/liquid mixture is processed by the pump, it flows smoothly, though some noise might be noticeable as gas passes through. This occurrence temporarily alters the pump's load, observable through fluctuations in outlet pressure and motor power consumption.

Q: What are the minimum and maximum speeds allowed?
A: The maximum speed for each model is specified in its data sheet; these values are established using a water as the standard medium. For handling viscous fluids, it becomes necessary to lower the maximum speed. The minimum speed is primarily influenced by motor start-up speed control, flow rate, and factors related to internal leakage.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, they are available with materials that comply with FDA regulations, ensuring safety and reliability.

Q: What is the recommended filtering level?
A: For optimal performance, a 25-micron filter should be installed at the pump's inlet. Ensure the filter surface is ample enough to prevent pressure drop and safeguard the pump's internal components.

Q: What affects pump and motor life?
A: The lifespan of our pumps is influenced by multiple factors. Key considerations include the frequency of on/off cycles, operational speed, load/pressure conditions, and fluid contamination levels.

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump load and motor torque surpass the magnetic coupling's capacity, causing the magnetic drive pump to become disengaged, often accompanied by noise. Immediate shutdown of the motor is crucial for troubleshooting when this situation arises.

Q: How do we adjust flow rate?
A: In positive displacement pumps, the simplest method to modify flow rate is by adjusting the motor speed, owing to the near-linear relationship between speed and flow.

Q: What is the starting capacity of the micro gear pump?
A: Starting capacity varies among pumps and depends on numerous factors such as fluid viscosity, line size, steam pressure, speed, and whether the pump is operating wet or dry.

Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to the flow of fluid from the pressure side back to the inlet through gear gaps, impacting efficiency. While this is a common concern for all gear pumps, precision micro gear pumps exhibit minimal leakage. Low-viscosity fluids traverse these gaps more readily, enhancing pump efficiency with thicker or more viscous fluids.

Q: What is cavitation?
A: Cavitation involves the creation of vapor cavities ('bubbles' or 'voids') in the liquid when the inlet pipe's diameter is insufficient for the pump's flow rate. These cavities form due to the fluid and pump system's physical properties, including available pressure, temperature, and pump speed. Cavitation often results in noise and accelerated pump wear.

Q: How do I identify Jonsn pump?
A: Every Jonsn pump is meticulously marked with our iconic LOGO and a precise laser-etched code right on the end face. This essential marking provides a clear indication of the manufacturing date, the specific product code, and a unique serial number (S/N). By using this S/N code, you can effortlessly trace back to the original configuration sheet and comprehensive test records, ensuring reliability and authenticity at every step.
