Q: What key factors should be considered during pump installation and in designing the pump's piping system?
A: For the best installation, place the pump beneath the tank, secure the motor base with screws, and ensure the medium's positive pressure at the pump inlet, especially for viscous media with low fluidity. Given the micro gear pump's compact size, avoid piping or instruments from exerting pressure on the pump body.
Keep the inlet pipe as short as possible, ensuring it is equipped with a filter to maintain cleanliness and particle-free conditions.
For viscous media, the pipe diameter should exceed the pump inlet size, following the diameters recommended by our selection software. Sometimes, a small inlet cannot fulfill flow requirements.
Q: What range of chemicals can the micro gear pump handle?
A: Our pumps are constructed from various materials, ensuring compatibility with most fluids. Thanks to the broad spectrum of operational conditions, When dealing with various conditions and fluids, it is always advisable to conduct a preliminary test of the pump in the actual circuit conditions it will operate under.

Q: How can we decide the input power of the pump?
A: At JONSN, we are equipped to precisely calculate the necessary input power based on your specific working requirements and the distinct characteristics of the fluid in question.
Q: What is the noise value of the pump?
A: The noise levels are influenced by factors such as pump installation, motor speed, and the type of fluid being used. Typically, the gear pump exhibits a reference noise level of 55 dB at a distance of 1 meter, under conditions of a 3 bar pressure difference and an operational speed of 3000 rpm.
Q: Can liquids containing solid particles be transported?
A: The design of gear pumps makes them unsuitable for transporting media containing solid particles, to ensure optimal performance and longevity.
Q: Can the pump be reversed?
A: While the factory standard indicates the preferred flow direction with an arrow, our pumps are versatile and can operate efficiently in both directions.
Q: Can the pump run dry?
A: Our gears and bushings, crafted from PEEK modified and post-treated materials, exhibit remarkable resistance to dry wear. We invite you to view our dry run test video for verification.

A: Absolutely, our pumps are self-priming. For comprehensive technical specifications, please refer to our datasheet.
Q: What is the operating temperature of the pump and motor?
A: Our conventional pump heads are engineered to perform seamlessly within a temperature range of -20°C to 80°C. Shouldthe operational temperature exceed 80°C or fall below this range, special considerations such as magnet type, clearances, and motor bearings must be evaluated. We encourage consultation for precise adaptability.
Q: How does viscosity affect gear pump and system performance?
A: Viscosity plays a critical role in pump efficiency. High-viscosity materials enhance volumetric efficiency by reducing internal leakage, necessitating a reduction in speed to avert overload. Conversely, low-viscosity fluids increase internal leakage, diminishing efficiency as outlet pressure rises. With constant pressure, speed, and medium temperature, the internal leakage rate stabilizes, maintaining a linear flow rate. For tailored advice, please reach out to our experts. Please consult our factory specialists for more specific information.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: The gas/liquid mixture will smoothly traverse the pump without significant issues. You might notice the pump sounding slightly noisier as gas navigates through. Additionally, momentary fluctuations may appear in the load on the pump, indicated by changes in outlet pressure and motor power consumption.
Q: What are the minimum and maximum speeds allowed?
A: The data sheet for each model specifies the maximum speed, tailored for water as the medium. For viscous fluids, it's essential to reduce the maximum speed. The minimum speed is influenced by the motor's starting speed control, flow rate, and internal leakage factors.
Q: Are Micro Gear Pumps FDA Approved?
A: Our pumps are available with materials compliant with FDA standards.
Q: What is the recommended filtering level?
A: It is advisable to install a 25-micron filter at the pump's inlet, ensuring a large enough filter surface to prevent pressure drop and safeguard the pump's internal components.
Q: What affects pump and motor life?
A: Numerous factors influence the service life. Key considerations include the number 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: Decoupling occurs if the pump's load and motor's torque capacity surpass the magnetic coupling's torque capacity, causing the magnetic drive pump to decouple and become noisy. Upon decoupling, the motor should immediately halt for troubleshooting.
Q: How do we adjust flow rate?
A: For positive displacement pumps, adjusting the motor speed is the simplest method to alter flow. There's a near-linear relationship between speed and flow.
Q: What is the starting capacity of the micro gear pump?
A: Starting capacity varies across pumps and depends on factors such as fluid viscosity, line size, vapor pressure, speed, and whether the pump is wet or dry.
Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to the portion of fluid on the pressure side that travels back to the inlet side through gear gaps, impacting efficiency. Precision micro gear pumps experience relatively minor internal leakage. Low-viscosity fluids pass through gaps more readily, making these pumps more efficient with thicker or more viscous fluids.
Q: What is cavitation?
A: Cavitation describes the formation of vapor cavities ('bubbles' or 'voids') in the liquid, often due to an inlet pipe diameter smaller than the pump's flow rate. These cavities arise from the fluid and pump system's physical properties (available pressure, temperature, pump speed...). Cavitation tends to cause noise and can lead to premature pump wear.
Q: How do I identify Jonsn pump?
A: Each pump features a LOGO and laser code on the end face for identification. These mark the date of manufacture, product code, and serial number (S/N). You can trace the original configuration sheet and test records using the S/N code.
