A: Standard pump heads can endure temperatures from -20°C to 80°C. Custom solutions are available for extreme temperatures ranging from lows of -60°C to highs of 160°C.
The conventional pump head system withstands pressures up to 4MPa, with certain systems enduring up to 6MPa.
The differential pressure between inlet and outlet exceeds 25bar, dependent on fluid viscosity.
Q: What considerations should be made when installing the pump? What factors are crucial in designing the pump's piping system?
A: For optimal design, position the pump below the tank, secure the motor base firmly, and ensure positive pressure is applied to the pump's inlet, especially crucial for viscous mediums which lack fluidity. Given the micro gear pump's compactness, it's essential to prevent piping or instrumentation from exerting pressure on the pump body.
Keep the inlet piping as short as feasible, ensuring it is equipped with a filter to maintain cleanliness and prevent particle ingress.
Pipe diameter considerations: For viscous medium transfer, it is advisable for the pipe diameter to exceed the pump inlet size. Use the diameter recommended by our selection software. Occasionally, a small inlet cannot fulfill flow demands.
Q: What types of chemicals can be transported by the micro gear pump?
A: Our pumps are crafted in diverse materials, ensuring compatibility with a wide array of fluids. Considering the vast diversity of operating conditions, conditions and fluids, we always recommend in any case to first test the pump in the circuit under the same conditions as it will actually run. If the material you transport contains dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide and other media, please contact us, if conventional pump head cannot transport this media, we can make customized solutions according to the working conditions.
Q: Can the pump be used for metering?
A: All of our pumps are positive displacement pumps for metering applications. Accuracy and repeatability will depend on the pump driver/control system used and the nature of the fluid, delivery accuracy can be +/-0.5%. Please contact us for details.

A: We offer a range of different drive types including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, Air Motor.
Q: How can we decide the input power of the pump?
A: JONSN can calculate the required input power according to your working requirements and fluid characteristics.
Q: What is the noise value of the pump?
A: Noise levels depend on pump installation, motor speed and fluid type. The gear pump has a reference value of 55 dB at 1 meter when the pressure difference is 3 bar and the speed is 3000 rpm.
Q: Can liquids containing solid particles be transported?
A: Gear pumps cannot transport media with particles.
Q: Can the pump be reversed?
A: Preferably the direction of the arrow is marked at the factory as the standard flow direction, but both directions can be run.
Q: Can the pump run dry?
A: Our gears and bushings are made of PEEK modified and post-treated, which has a strong ability to resist dry wear. You can view our dry run test video. However, dry running should be minimized to avoid shortening pump life.
Q: Is the pump self-priming?
A: Yes, please refer to our datasheet.
Q: What is the operating temperature of the pump and motor?
A: Our conventional pump heads can operate normally at a temperature of -20 ~ 80°C. 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: Viscous materials can increase the volumetric efficiency of the pump and reduce the leakage of the gear pump. However, depending on the viscosity, the speed needs to be reduced to prevent overloading. Low-viscosity fluid will lead to greater internal leakage. As the outlet pressure increases, the internal leakage increases and and the volumetric efficiency decreases. When the pressure, speed, and medium temperature remain constant, the internal leakage rate will remain constant, and the flow rate will remain linear relationship. Please consult factory for details.
Q: What occurs when a mixture of gas and liquid is introduced into a gear pump?
A: The gear pump seamlessly processes a gas/liquid mixture, although the operation may become audibly more pronounced as gas traverses through. During this phase, there might be temporary adjustments in the pump's load, observable through variations in outlet pressure and the motor's energy consumption.
Q: What are the permissible minimum and maximum operational speeds?
A: Each model's data sheet specifies the maximum speed, tailored to water as a standard medium. as medium. For handling viscous liquids, the maximum speed should be lowered. The minimum speed is largely influenced by motor start-up control, flow rate, and factors such as internal leakage.
Q: Are Micro Gear Pumps certified by the FDA?
A: Yes, pumps can be equipped with materials that meet FDA compliance standards.
Q: What is the advised level of filtration?
A: To ensure optimal protection and efficiency, a 25-micron filter is advocated at the pump's inlet. The filter should possess an adequately large surface area to prevent pressure drops and safeguard the pump's internals.
Q: Which elements influence the longevity of a pump and its motor?
A: A multitude of factors impact the durability of pumps. Primary aspects include the frequency of on/off cycles, operational speed, pressure load, and levels of fluid contamination.
Q: Could you explain decoupling (also known as demagnetization)? Can it serve as a safety mechanism?
A: Decoupling occurs when the pump's load and motor's torque capacity surpass the magnetic coupling's limits, resulting in a noisy magnetic drive pump. In such events, it is crucial for the motor to halt instantly for troubleshooting.
Q: How can we regulate the flow rate?
A: For positive displacement pumps, adjusting the motor speed is the most straightforward method to modulate flow. The relationship between speed and flow is nearly direct and proportional.
Q: What is the initial operational capability of a micro gear pump?
A: Starting capability is variable across different pumps and is contingent on factors such as fluid viscosity, pipeline dimensions, vapor pressure, speed, and whether the pump operates in a wet or dry condition.
Q: Could you define internal leakage in a gear pump?
A: Internal leakage refers to the phenomenon where a fraction of fluid on the pressure side reverts to the inlet side via the gear gap, impacting efficiency. While inherent to all gear pumps, precision micro gear pumps exhibit minimal internal leakage, thus providing higher efficiency with thicker or more viscous fluids.
Q: What is cavitation?
A: Cavitation involves the creation of vapor cavities (commonly termed 'bubbles' or 'voids') within the liquid, often resulting from an inlet pipe with a diameter smaller than the pump's flow rate capabilities. These voids emerge due to the fluid dynamics and physical attributes of the pump system, including pressure, temperature, and pump speed. Cavitation is typically associated with increased noise and accelerated wear of the pump.
Q: How can I identify a Jonsn pump?
A: Every pump is distinctly marked with a LOGO and laser-etched code on its end face, detailing the manufacturing date, product code, and serial number (S/N). Comprehensive details including the original configuration sheet and test records are traceable via the S/N code.
