Q: What are the specifications for temperature resistance, pressure endurance, and differential pressure?
A: Standard pump heads resist temperatures from -20°C to 80°C, with custom options available for as low as -60°C and as high as 160°C.
Our typical pump head system withstands pressures up to 4MPa, while certain systems are designed for 6MPa resistance.
The pressure differential between the inlet and outlet exceeds 25 bar, adaptable to viscosity variations.
Q: What considerations are necessary for pump installation, and what factors should influence the piping system's design?
A: It is optimal to mount the pump below the tank, ensuring the motor base is securely fastened, and the medium's positive pressure is directed to the pump inlet, particularly for viscous mediums with limited flow. Due to the compact design of the micro gear pump, avoid external pressure from piping or instrumentation on the pump body.
Keep the inlet pipe as short as feasible, ensuring it is equipped with a filter to maintain cleanliness and particle-free flow.
Regarding pipe diameter: For viscous media transport, ensure the pipe exceeds the pump inlet size. Utilize the pipe diameter recommended by our selection software. Occasionally, an undersized inlet fails to meet flow demands.
Q: What chemicals can be transferred using the micro gear pump?
A: Our versatile pumps are constructed from diverse materials, enabling compatibility with a wide range of fluids. Given the extensive variety of working To ensure optimal performance in your specific conditions and with various fluids, we highly recommend testing the pump under real-world operating conditions. If your transported material includes dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar substances, please reach out to us for specialized guidance. If a typical pump head is unable to effectively convey such media, Jonsn can offer bespoke solutions tailored to your operational requirements.
Q: Can the pump be used for metering?
A: Indeed, all of our pumps function as positive displacement pumps suitable for metering purposes. With precision and consistency, the accuracy of delivery can be +/-0.5%, though this might vary based on the pump driver/control system and the fluid characteristics. For more in-depth information, please contact us.

Q: How can we decide the input power of the pump?
A: JONSN is equipped to calculate the necessary input power based on your operational needs and fluid properties.
Q: What is the noise value of the pump?
A: The noise level is influenced by factors such as pump installation, motor speed, and fluid type. As a standard, our gear pump exhibits a noise level of approximately 55 dB from a distance of 1 meter, at a pressure differential 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 that contains solid particles.
Q: Can the pump be reversed?
A: While the preferred direction indicated by the factory is standard, our pumps are versatile and can operate efficiently in both forward and reverse directions.
Q: Can the pump run dry?
A: Our pumps feature PEEK-modified gears and bushings that are specifically engineered to withstand dry wear. You can access our dry run test video for reference, although it's advisable to minimize dry running to prolong pump longevity.
Q: Is the pump self-priming?
A: Absolutely, and you can find detailed specifications in our datasheet.
Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads are designed to function optimally across a broad temperature range of -20 ~ 80°C. Should you require operation beyond80°C or other specific conditions, additional considerations such as magnet type, clearance, and motor bearings should be discussed with us for tailored advice.
Q: How does viscosity affect gear pump and system performance?
A: Viscosity plays a critical role by enhancing the pump's volumetric efficiency while minimizing leakage. However, adjustments to speed may be needed to prevent overloads. While low-viscosity fluids might increase internal leakage, as outlet pressure rises, internal leakage can elevate, subsequently reducing volumetric efficiency. With constant pressure, speed, and medium temperature, internal leakage stabilizes, maintaining a consistent flow rate. For a detailed analysis, pleaseconsult our expert team.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: When a gas/liquid mixture flows through the gear pump, it seamlessly passes without any obstruction. The presence of gas may elevate the noise levels, yet this is normal. Additionally, there might be a temporary alteration in the pump's load, which manifests as fluctuations in outlet pressure and motor power usage.
Q: What are the minimum and maximum speeds allowed?
A: Each model's data sheet specifies the maximum speed, specifically calibrated for water as the medium. as medium. However, for fluids with higher viscosity, the speed must be adjusted downward. The minimum speed is predominantly influenced by motor startup controls, flow rates, and factors like internal leakage.
Q: Are Micro Gear Pumps FDA Approved?
A: Yes, our pumps can be manufactured with materials that comply with FDA standards.
Q: What is the recommended filtering level?
A: To ensure optimal performance, a 25-micron filter should be installed at the pump's inlet. This filter must have a sufficiently large surface to prevent pressure drops and safeguard the pump's internal components.
Q: What affects pump and motor life?
A: Numerous factors influence the longevity of the pump and motor. Key elements include the frequency of switching on/off cycles, operating speed, pressure load, and the purity of fluid being used.
Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump's load and the motor's torque capacity surpass the magnetic coupling's limit, causing the magnetic drive pump to become disengaged and produce noise. This calls for an immediate motor halt for effective troubleshooting.
Q: How do we adjust flow rate?
A: For positive displacement pumps, the most straightforward method to modify the flow rate is by tweaking the motor's speed. The relationship between speed and flow is nearly linear.
Q: What is the starting capacity of the micro gear pump?
A: The starting capacity varies across different pumps and hinges on several factors such as fluid viscosity, pipe dimensions, vapor pressure, speed, and whether the pump is in a wet or dry state.
Q: What is internal leakage of gear pump?
A: Internal leakage refers to a portion of the fluid on the pressure side flowing back to the inlet through gear gaps, impacting efficiency. Despite being a common issue for all gear pumps, precision micro gear pumps experience minimal leakage. Low-viscosity fluids traverse these narrow gaps effortlessly, enhancing efficiency, particularly with thicker fluids.
Q: What is cavitation?
A: Cavitation involves vapor cavity formation (bubbles or voids) in the liquid due to a mismatch between the inlet pipe diameter and pump flow rate. These cavities result from the fluid and pump system's physical properties, including available pressure, temperature, and pump speed. Cavitation often leads to noise and accelerated pump wear.
Q: How do I identify Jonsn pump?
A: Each Jonsn pump is fitted with a LOGO and a laser-etched code on its face, detailing the manufacture date, product code, and serial number (S/N). You can trace the original configuration sheet and test records using the S/N code.
