The conventional pump head system boasts a pressure resistance of up to 4MPa, while select systems can withstand a remarkable 6MPa.
The pressure difference across the inlet and outlet exceeds 25 bar, contingent on 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: In designing, it is optimal to install the pump beneath the tank, securely fasten the motor base with screws, and ensure positive pressure of the medium is introduced to the pump inlet, especially for viscous media with limited fluidity. Given the compact nature of the micro gear pump, it's crucial to prevent piping or instrumentation from exerting pressure on the pump body.

Minimize the length of the inlet pipe, ensuring it is equipped with a filter to maintain cleanliness and prevent particle contamination. shoube be equipped with a filter to keep the pipe clean and free of particles.
Pipe diameter requirements: When dealing with the complexities of conveying viscous media, it is essential to ensure that the pipe diameter exceeds that of the pump inlet. Compliance with our company's recommended pipe diameter as specified in our selection software will optimize performance. Inadequate inlet sizes may fail to meet desired flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our pumps are adeptly crafted from a variety of materials, ensuring compatibility with most fluids. However, due to the extensive range of working conditions and fluid types, we strongly advise testing the pump within your circuit under conditions mimicking actual use. Should your transported materials include dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar substances, please reach out to us for assistance. If standard pump heads prove incapable of handling these media,we can tailor solutions to align with specific operational requirements.

Q: Can the pump be used for metering?
A: Indeed, all our pumps function as precision positive displacement pumps suitable for metering applications. The accuracy and repeatability are influenced by the pump driver/control system employed and fluid characteristics, achieving a delivery accuracy of +/-0.5%. For comprehensive insights, please contact us.

Q: Which motors can be used?
A: We provide an extensive assortment of drive types, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, to cater to diverse application needs.

Q: How can we decide the input power of the pump?
A: JONSN offers precise calculations for the requisite input power, tailored to your operational demands and fluid attributes.


Q: What is the noise value of the pump?
A: Noise levels are contingent upon the pump installation, motor speed, and fluid type. Typically, our gear pump registers a reference noise level of 55 dB at a distance of 1 meter, with a pressure differential of 3 bar and a speed of 3000 rpm.

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

Q: Can the pump be reversed?
A: While the standard flow direction is indicated by an arrow at the factory, our pumps are versatile enough to operate in both directions.

Q: Can the pump run dry?
A: Our gears and bushings, crafted from PEEK that is both modified and post-treated, exhibit exceptional resistance to dry wear. We invite you to view our dry run test video. However, it is advisable to minimize dry running to preserve pump longevity.

Q: Is the pump self-priming?
A: Yes, indeed. For comprehensive specifics, kindly refer to our datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our conventional pump heads are engineered to operate efficiently between -20°C and 80°C. If the temperature exceeds 80°C or differs significantly, please reach out to us as factors such as magnets, clearances, and motor bearings warrant careful consideration.

Q: How does viscosity affect gear pump and system performance?
A: Viscous materials significantly enhance the volumetric efficiency of our gear pump, seamlessly reducing leakage. However, it's crucial to adjust speed according to viscosity levels to avert potential overload issues. In contrast, low-viscosity fluids may cause more internal leakage. As the outlet pressure elevates, internal leakage tends to increase, consequently decreasing volumetric efficiency. When pressure, speed, and medium temperature are stabilized, the internal leakage rate remains steady, ensuring a consistent and linear flow rate. Please consult factory for details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: With our advanced gear pump design, gas/liquid mixtures are processed effortlessly, although the pump may sound noisier when gas is present. There will be a brief shift 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 provides the specific maximum speed, calculated based on water as the standard medium. For handling viscous fluids, a reduction in the speed is necessary. The minimum speed is primarily determined by motor starting speed control, flow rate, and internal leakage factors.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, our pumps are made with FDA-compliant materials, ensuring safe and reliable operation.

Q: What is the recommended filtering level?
A: We recommend installing a 25-micron filter at the pump's inlet, with a sufficiently large filter surface to prevent pressure drops and safeguard the pump's internal components.

Q: What affects pump and motor life?
A: Various factors can impact the longevity of our pumps. Key considerations include the frequency of on/off cycles, operational speed, load (pressure), and the cleanliness of the fluid being pumped.

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump's load and motor's torque capacity surpass the magnetic coupling's torque capacity, causing the magnetic drive pump to become noisy and ineffective. In such cases, it's essential to stop the motor immediately for troubleshooting to ensure safety and functionality.

Q: How do we adjust flow rate?
A: Adjusting flow in our positive displacement pumps is effortlessly done by altering the motor speed, as there is a nearly linear relationship between speed and flow rate, allowing precise control.

Q: What is the starting capacity of the micro gear pump?
A: Starting capability varies across different models and is influenced by 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 portion of the pressurized fluid flowing back to the inlet side through gear gaps, affecting efficiency. Although common in all gear pumps, our precision micro gear pumps minimize this leakage. Low-viscosity fluids navigate these gaps more readily, making the pumps ideal for thicker, more viscous liquids.

Q: What is cavitation?
A: Cavitation is the formation of vapor cavities ('bubbles' or 'voids') within the liquid, often due to the inlet pipe diameter being smaller than the pump's capacity. These cavities result from the fluid and pump system's physical properties (available pressure, temperature, speed...). Cavitation can lead to increased noise and accelerated pump wear.

Q: How do I identify Jonsn pump?
A: Each of our precision-engineered pumps proudly displays a distinct LOGO and laser code on its end face. This marking serves as a unique identifier, revealing crucial details such as the date of manufacture, product code, and serial number (S/N). With the S/N code, you can seamlessly trace back to the original configuration sheet and test records, ensuring a trustworthy and verifiable product history.
