The standard pump head system withstands pressures up to 4MPa, with select systems enduring pressures as high as 6MPa.
The differential pressure across the inlet and outlet exceeds 25bar, contingent upon the viscosity, ensuring robust performance.

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, it is recommended that the pump be installed below the tank, securing the motor base with screws, and ensuring the medium's positive pressure is directed into the pump inlet, which is especially crucial for viscous mediums with limited fluidity. Given the compact dimension of the micro gear pump, it is imperative to avoid any piping or instrumentation pressing against the pump body.

The inlet pipe should be as brief as feasible, and it should be equipped with a filter to maintain cleanliness and particle-free operation.
Pipe Diameter Requirements: When handling viscous media, achieving optimal flow is paramount. It is strongly advised that the pipe's diameter exceed the pump inlet size for seamless operation. Our company's selection software provides precise recommendations for pipe sizes. An undersized inlet could hinder the flow, thus adhering to advised specifications ensures efficient performance.


Q: What chemicals can the micro gear pump transport?
A: Our pumps are meticulously crafted in various materials to accommodate a vast array of fluids. Each pump is designed to be compatible with specific substances, ensuring versatility and adaptability across numerous applications. Given the plethora of working conditions and fluids, we emphasize the importance of preliminary testing. Assessing the pump within its operational circuit replicates real-world conditions, confirming compatibility. Should you work with chemicals such as dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar substances, reach out to us for tailored solutions. if conventional pump head cannot transport this media, we can present bespoke modifications tailored to specific working conditions.

Q: Can the pump be used for metering?
A: Every pump we offer is a positive displacement pump specifically suited for precise metering applications. The outstanding accuracy and reliability of our pumps is influenced by the driver/control system and the fluid characteristics. Our pumps can achieve a delivery accuracy of +/-0.5%.

A: We provide an extensive selection of drive types to match your specific needs, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor. Each type offers unique advantages tailored to various applications.

Q: How can we decide the input power of the pump?
A: JONSN is equipped to calculate the precise input power your application requires. By analyzing your working conditions and fluid properties, we ensure that your system operates efficiently and effectively.


Q: What is the noise value of the pump?
A: Noise levels are contingent on several factors, including pump installation, motor speed, and fluid type. Typically, our gear pumps produce a sound level of about 55 dB at a distance of 1 meter when operating at a pressure difference of 3 bar and a speed of 3000 rpm, ensuring a quiet and smooth operation.

Q: Can liquids containing solid particles be transported?
A: Unfortunately, gear pumps are not designed to handle media containing solid particles. To maintain optimal pump functionality, it is crucial to avoid particle-laden liquids.

Q: Can the pump be reversed?
A: While standard operations follow the factory-marked direction of flow, our pumps offer flexibility and can operate in both directions, expanding their application versatility.

Q: Can the pump run dry?
A: Our pumps boast gears and bushings made from PEEK that have undergone modification and post-treatment to enhance dry-running resilience. You can observe our dry run test in the detailed video. However, minimizing dry runs is advisable to prolong the pump's lifespan.

Q: Is the pump self-priming?
A: Indeed, our pumps are self-priming. For comprehensive specifications, please consult our detailed datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads are engineered for robust performance within a temperature range of -20 to 80°C. For specialized applications where temperatures exceed 80°C, additional factors such as magnet materials, clearance tolerances, and motor bearing specifications must be considered to ensure optimal function. Please consult us if the temperature exceeds 80°C or other temperatures, factors such as magnets, clearances, and motor bearings need to be considered.

Q: How does viscosity affect gear pump and system performance?
A: Elevate your pump's performance with viscous materials! These materials boost volumetric efficiency and minimize gear pump leakage. However, remember to adjust speed according to viscosity to avoid overload. Low-viscosity fluids might cause increased internal leakage, especially as outlet pressure rises, leading to decreased volumetric efficiency. When pressure, speed, and temperature are stable, internal leakage remains unchanged, keeping the flow rate consistently linear. Please consult the factory for comprehensive details.

Q: What occurs when a gas and liquid mixture is pumped through a gear pump?
A: Rest assured, the gas/liquid mixture smoothly traverses the pump. However, expect increased pump noise when gas is involved. Also, be prepared for temporary fluctuations in outlet pressure and motor power consumption as the load on the pump varies.

Q: What are the permissible speed limits?
A: Each model's data sheet specifies the maximum speed, tailored for water as a medium. For viscous fluids, it's crucial to lower the maximum speed. The minimum speed is influenced by motor starting speed control, flow rate, and internal leakage considerations.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, our pumps are crafted using FDA compliant materials, ensuring safety and quality.

Q: What is the recommended filtering level?
A: Enhance your pump's longevity by installing a 25-micron filter at the inlet. Ensure the filter surface is expansive enough to prevent pressure drops and safeguard the pump's inner components.

Q: What influences the lifespan of pumps and motors?
A: Multiple factors play a role in determining service life. Pay attention to on/off cycles, operating speed, load (pressure), and fluid contamination.

Q: What is decoupling (also known as demagnetization)? Can it serve as a safety feature?
A: Decoupling occurs when the pump load and motor torque demand exceed the magnetic coupling's limit, resulting in a noisy pump. Immediate motor shutdown is essential for troubleshooting when this happens.

Q: How do we fine-tune flow rate?
A: Adjusting flow is effortless in positive displacement pumps-simply modify the motor speed. There's a near-linear connection between speed and flow rate.

Q: What is the initial capacity of the micro gear pump?
A: Starting capacity varies by pump and depends on factors like fluid viscosity, line size, steam pressure, speed, and whether the pump is operating wet or dry.

Q: What entails internal leakage in a gear pump?
A: Internal leakage in gear pumps is when fluid on the pressure side seeps back to the inlet side through gear gaps, reducing efficiency. Precision micro gear pumps have minimal leakage, and they excel with viscous fluids as low-viscosity fluids easily traverse small gaps, enhancing efficiency with thicker fluids.

Q: Can you explain cavitation?
A: Cavitation refers to vapor cavity formation ("bubbles" or "voids") in the liquid, often due to an inlet pipe diameter smaller than the pump's flow rate. It's driven by the fluid and pump system's physical attributes (pressure, temperature, speed). Cavitation can cause noise and accelerate pump wear.

Q: How do I identify Jonsn pump?
A: Each pump is distinctively marked with our prestigious LOGO and a precisely engraved laser code on its end face. This ensures effortless identification of the manufacturing date, product code, and unique serial number (S/N). For added assurance, you can conveniently trace the original configuration sheet and meticulous test records using the S/N code.
