Conventional pump head systems endure pressures up to 4MPa, while specific models sustain up to 6MPa.
The pressure differential between the inlet and outlet exceeds 25bar, depending on viscosity.
Q: What factors should be taken into account during pump installation? What considerations are vital for designing the pump's piping system?
A: For optimal design, install the pump below the tank, securing the motor base with screws, and ensure positive pressure of the medium at the pump inlet, especially for viscous mediums with low fluidity. Given the micro gear pump's compact size, prevent piping or instruments from pressing against the pump body.
The inlet pipe should be as short as possible, equipped with a filter to maintain cleanliness and particle-free conditions. shoube be ensuring the pipe remains free of debris.
For viscous media, the pipe diameter should exceed the pump inlet size, following our selection software's recommendations. At times, inadequate inlet size may hinder flow requirements.
Q: What types of chemicals can the micro gear pump effectively transport?
A: Our precision-engineered pumps come in a diverse array of materials, enabling compatibility with a vast range of fluids. Given the multitude of diverse operating conditions and fluid types, we strongly advise testing the pump within your specific operational circuit before full deployment. Should your conveyed material include dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or other specialized media, we urge you to reach out if the conventional pump head proves inadequate to handle these substances,for we offer tailored solutions crafted to meet your unique operational demands.
Q: Is your pump suitable for metering applications?
A: Absolutely! All our pumps function as positive displacement pumps perfect for precise metering tasks. The driver/control system employed, alongside the fluid's nature, determines the accuracy and repeatability, with delivery precision reaching an impressive +/-0.5%. Reach out to us for comprehensive insights.

A: JONSN stands ready to accurately compute the requisite input power tailored to your specific operational demands and fluid properties, ensuring optimal performance.
Q: What are the noise specifications of your pump?
A: The acoustic signature of our pumps varies by installation, motor speed, and fluid dynamics. With a reference noise level of 55 dB at 1 meter, under a 3 bar pressure difference and 3000 rpm, our gear pump operates with remarkable quietude.
Q: Are your pumps capable of transporting liquids with solid particles?
A: Gear pumps are not designed to handle fluids containing solid particles.
Q: Is bidirectional flow possible with your pumps?
A: While the standard flow direction is factory-indicated with an arrow, our pumps are versatile enough to operate efficiently in both directions.
Q: Can your pumps run without fluid?
A: Our gears and bushings, crafted from PEEK and modified for durability, boast exceptional dry-running resistance. A dry run test video is available for reference. Nonetheless, we advise minimizing dry operation to prolong pump lifespan.
Q: Do your pumps have self-priming capabilities?
A: Indeed, they do. For further details, please consult our comprehensive datasheetfor specifications.
Q: What are the thermal operating limits for your pump and motor?
A: Our standard pump heads function optimally within a temperature range of -20 to 80°C. We recommend consulting us if exceeding 80°C, as factors like magnets, clearances, and motor bearings require careful consideration. Please connect with usshould you encounter temperatures exceeding this range, as adjustments may be necessary.
Q: How does fluid viscosity impact the gear pump and system performance?
A: Viscous substances boost the pump's volumetric efficiency and decrease leakage, though speed adjustments may be needed to avert overload. Conversely, low-viscosity fluids increase leakage. With constant pressure, speed, and temperature, leakage remains steady, maintaining a linear flow relationship. Kindly consultthe factory for comprehensive details.
Q: What occurs when a gas and liquid mixture is processed by a gear pump?
A: The gas/liquid blend seamlessly traverses the pump, albeit potentially increasing noise during gas transit. A transient alteration in the pump's load may manifest as fluctuations in both outlet pressure and motor power consumption.
Q: What are the permissible minimum and maximum operating speeds?
A: Refer to each model's data sheet for its specified maximum speed, noting that these parameters are set with water as the benchmark medium. When dealing with viscous fluids, the highest permissible speed should be adjusted downward. The minimum speed chiefly relies on motor start-up control, desired flow rate, and internal leakage considerations.
Q: Are Micro Gear Pumps certified by the FDA?
A: Our pumps are available with materials that meet FDA compliance standards.
Q: What filtration level is advisable?
A: A 25-micron filter is recommended for installation at the pump's inlet. Ensure the filter has a substantial surface area to prevent pressure drops and safeguard the pump's internal components.
Q: What influences the longevity of the pump and motor?
A: Numerous factors impact their service life. Critical considerations include the frequency of on/off cycles, operational speed, load pressure, and the presence of fluid contaminants.
Q: Could you explain decoupling (also known as demagnetization)? Can it function as a safety mechanism?
A: When a pump's load and motor's torque capacity surpass the magnetic coupling's capacity, the magnetic drive pump may decouple, causing noise. Immediate cessation of motor operation is advised for troubleshooting when decoupling occurs.
Q: How is the flow rateregulated?
A: For positive displacement pumps, the most straightforward approach to modify flow is by altering the motor speed. There is an almost direct correlation between speed and flow rate.
Q: What defines the micro gear pump's starting capacity?
A: Starting capacity varies per pump and is contingent upon factors such as fluid viscosity, line dimensions, vapor pressure, speed, and whether the pump operates dry or wet.
Q: Could you define internal leakage in a gear pump?
A: Internal leakage refers to fluid returning from the pressure side to the inlet side via gear gaps, impacting efficiency. While a universal gear pump concern, precision micro gear pumps exhibit reduced leakage. Low-viscosity fluids pass through minor gaps more easily, enhancing efficiency in thicker or more viscous fluids.
Q: What is the phenomenon of cavitation?
A: Cavitation involves the creation of vapor bubbles or voids in the liquid, often due to the inlet pipe's diameter being inadequate for the pump's flow rate. Influenced by fluid and system properties (available pressure, temperature, and pump speed), cavitation can lead to noise and accelerated pump wear.
Q: How can I identify a Jonsn pump?
A: Each pump features a distinct LOGO and laser-etched code on its end face. These identifiers include the manufacturing date, product code, and serial number (S/N). The serial number enables tracing of the original configuration sheet and test records.
