Q: What are the specifications for temperature resistance, pressure resistance, and differential pressure?
A: Standard pump heads offer temperature resistance ranging from -20°C to 80°C. Custom options are available for extremes as low as -60°C and as high as 160°C.
The standard pump head system withstands pressures up to 4MPa, with certain systems enduring up to 6MPa.
The differential pressure between inlet and outlet exceeds 25bar, subject to viscosity conditions.

Q: What considerations are essential for pump installation and pump piping system design?
A: During design, the pump should ideally be positioned below the tank. Secure the motor base with screws, ensuring input of medium pressure to the pump's inlet, crucial for viscous media with limited fluidity. Given the micro gear pump's compact size, ensure no piping or instrumentation applies pressure to the pump body.

The inlet pipe should be minimized in length, and it should be fitted with a filter to maintain cleanliness, free from particulate contamination.
Pipe diameter requirements: When conveying viscous media, ensure the pipe diameter exceeds the pump inlet size for optimal flow. Our advanced selection software recommends the ideal pipe diameter, guaranteeing seamless operation. If the inlet size is insufficient, it may hinder the flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our pumps are crafted from various materials, ensuring compatibility with a vast range of fluids. Considering the diverse array of working conditions and fluids, we highly suggest testing the pump in your specific circuit conditions before standard application. Should your materials include substances like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or other complex media, reach out to us for specialized assistance. If conventional pump heads cannot transport these media, we can engineer tailored solutions to match your exact working conditions and requirements.

Q: Can the pump be used for metering?
A: Indeed, our pumps are designed as positive displacement pumps ideal for metering applications. While accuracy and repeatability hinge on the pump driver/control system and fluid nature, you can expect delivery precision as high as +/-0.5%. Reach out to us for comprehensive details.

Q: Which motors can be used?
A: We provide a diverse array of drive options, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, catering to various requirements and applications.

Q: How can we decide the input power of the pump?
A: JONSN offers precise calculations for the necessary input power, tailored to your working requirements and the unique characteristics of your fluid, ensuring efficient performance.


Q: What is the noise value of the pump?
A: Noise levels vary based on installation, motor speed, and fluid type. Our gear pump typically produces a sound 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: Our 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 for optimal operation, our pumps can be configured to run in both directions seamlessly.

Q: Can the pump run dry?
A: Our gears and bushings, crafted from PEEK with advanced modification and post-treatment, exhibit exceptional dry wear resistance. Although you can view our dry run test video, it's advisable to minimize dry running to preserve the pump's longevity.

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

Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads function optimally within a temperature range of -20 to 80°C. For temperatures beyond 80°C or other extremes, consultation is advised to address considerations like magnets, clearances, and motor bearings. Please consult us ifthe 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: Viscous materials are a boon for increasing the volumetric efficiency of the pump while significantly reducing leakage in gear pumps. However, as the viscosity varies, it's crucial to adjust the speed to prevent overloading. On the flip side, low-viscosity fluids tend to result in higher internal leakage. With rising outlet pressure, expect an increase in internal leakage, consequently diminishing volumetric efficiency. When pressure, speed, and medium temperature remain steady, the internal leakage rate stabilizes, maintaining a linear relationship with flow rate. Please consult factory for details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: Rest assured, a gas/liquid mixture can seamlessly traverse through the pump. While gas is passing, you might notice increased noise levels. Additionally, expect a brief fluctuation in the pump's load, observable through changes in the outlet pressure and the motor's power consumption.

Q: What are the minimum and maximum speeds allowed?
A: The maximum speed for each model is outlined in the data sheet, tailored for water as medium. For viscous fluids, it's essential to reduce the maximum speed to ensure optimal performance. The minimum speed is primarily dictated by motor starting speed control, flow rate, and factors influencing internal leakage.

Q: Are Micro Gear Pumps FDA Approved?
A: Our pumps come equipped with options for FDA compliant materials, ensuring safety and reliability.

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

Q: What affects pump and motor life?
A: Numerous elements influence the service life of pumps and motors. Key considerations include the frequency of on/off cycles, operating speed, load (pressure), and fluid contamination.

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: When the pump load and motor's torque capacity surpass the magnetic coupling's limits, decoupling occurs, leading to increased noise. In such instances, the motor should halt immediately for further diagnostics, serving as a crucial safety measure.

Q: How do we adjust flow rate?
A: To tweak the flow in positive displacement pumps, the most straightforward method is altering the motor speed. A nearly linear correlation exists between speed and flow, allowing precise control.

Q: What is the starting capacity of the micro gear pump?
A: The starting capacity varies across different pumps and hinges on several factors including fluid viscosity, line size, steam pressure, speed, and the condition of the pump (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 from the pressure side escapes back to the inlet side through gear gaps, impacting efficiency. It's a typical challenge for gear pumps. However, precision micro gear pumps exhibit relatively minimal internal leakage, making them more efficient in handling thicker or more viscous fluids.

Q: What is cavitation?
A: Cavitation involves the creation of vapor cavities ('bubbles' or 'voids') in the liquid, often due to an inlet pipe diameter being too small for the pump's flow rate. These cavities arise from the fluid's characteristics and the pump system's physical properties (available pressure, temperature, pump speed, etc.). Cavitation can lead to noise and premature pump wear, demanding attention.

Q: How do I identify Jonsn pump?
A: Every Jonsn pump is meticulously marked with a distinct LOGO and precise laser code on its end face. These identifiers detail the production date, unique product code, and serial number (S/N). Furthermore, the serial number is your gateway to accessing the original configuration sheet and comprehensive test records, ensuring complete traceability and assurance of quality.
