A: Our standard pump heads are engineered to resist temperatures from -20°C to 80°C, with customization options available for low temperatures as extreme as -60°C and high temperatures up to a remarkable 160°C.
Our conventional pump head systems withstand pressures of 4MPa, with certain models rated for up to 6MPa.
The pressure difference between the inlet and outlet exceeds 25bar (contingent on viscosity).

Q: What factors should be considered in the installation of the pump? What should be considered when designing the piping system of the pump?
A: In design planning, ideally, install the pump beneath the tank, ensuring the motor base is securely fastened with screws, and direct the medium's positive pressure towards the pump inlet, especially when dealing with viscous mediums exhibiting poor fluidity. Given the compact nature of the micro gear pump, it is crucial to avoid exerting pressure from piping or instrumentation on the pump body.

The inlet pipe should be as concise as possible, with the inlet pipe equipped with a filter to maintain cleanliness and prevent particle intrusion within the pipe.
Pipe Diameter Requirements: When transporting viscous media, the pipe must be larger than the pump inlet size to ensure optimal flow rates. Our company's selection software offers precise pipe diameter recommendations, tailored to meet your specific needs. In certain cases, the inlet may prove too small to satisfy flow requirements.


Q: What chemicals can the micro gear pump transport?
A: Our pumps are crafted from diverse materials, ensuring compatibility with a broad spectrum of fluids. Working conditions and fluid types can vary greatly, thus, it's crucial to test the pump within the actual circuit conditions prior to operation. If you need to pump substances like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar, do not hesitate to reach out to us. If the conventional pump head cannot transport these media,we offer tailored solutions based on your specific working conditions.

Q: Can the pump be used for metering?
A: Indeed, all our pumps are positive displacement designs, perfectly suited for metering tasks. The accuracy, reaching up to +/-0.5%, hinges on the pump driver/control system used and the fluid's characteristics. Please contact us for comprehensive insights.

Q: Which motors can be used?
A: We provide a diverse selection of drive types including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, ensuring adaptability to various application needs.

Q: How can we decide the input power of the pump?
A: JONSN accurately determines the necessary input power based on your unique working requirements and the specific fluid characteristics involved.


Q: What is the noise value of the pump?
A: Noise levels are influenced by installation specifics, motor speed, and fluid type. Typically, the gear pump maintains a reference noise level of 55 dB at a 1-meter distance when operating at a pressure difference of 3 bars and a speed of 3000 rpm.

Q: Can liquids containing solid particles be transported?
A: Our gear pumps are not designed to handle media containing solid particles.

Q: Can the pump be reversed?
A: Although the standard flow direction is indicated by an arrow at the factory, the pump is capable of running in both directions, offering versatility in operation.

Q: Can the pump run dry?
A: Crafted with PEEK-modified and post-treated gears and bushings, our pumps are equipped with robust dry wear resistance. While we offer dry run test videos for your reference, minimizing dry running is advisable to prolong pump life.

Q: Is the pump self-priming?
A: Yes, our datasheet provides detailed information on self-priming capabilities..

Q: What is the operating temperature of the pump and motor?
A: Our conventional pump heads function seamlessly within a temperature range of -20°C to 80°C. Please consult us if temperatures exceed 80°C or fall outside this range, as magnetics, clearances, and motor bearings need careful consideration.

Q: How does viscosity affect gear pump and system performance?
A: Viscous materials can enhance the volumetric efficiency of gear pumps by minimizing leakage, yet it's crucial to adjust the speed to prevent overload depending on viscosity. Conversely, low-viscosity fluids may cause increased internal leakage. As outlet pressure amplifies, so does internal leakage, leading to a decrease in volumetric efficiency. If pressure, speed, and medium temperature remain stable, internal leakage rates and flow maintain a linear relationship. Please consult the factory for comprehensive details.

Q: What occurs when a gas and liquid mixture is channeled through a gear pump?
A: A gas/liquid mixture traverses the pump smoothly, although it may result in increased noise levels as gas passes. Temporary load variations can occur, detectable through fluctuations in outlet pressure and motor power consumption.

Q: What are the permissible minimum and maximum speeds?
A: Each model's data sheet specifies maximum speed limits, primarily based on the water as a medium. For fluids with higher viscosity, the maximum speed should be reduced. The minimum speed is influenced by motor starting speed control, flow rate, and internal leakage considerations.

Q: Are the Micro Gear Pumps compliant with FDA standards?
A: Yes, pumps are available with materials compliant with FDA regulations.

Q: What is the advised filtration level?
A: It is advised to use a 25-micron filter at the pump inlet, ensuring a large enough filter surface to prevent pressure drops and protect internal pump components.

Q: What factors influence the longevity of pumps and motors?
A: Numerous factors impact service life, with critical considerations including the frequency of on/off cycles, operational speed, load (pressure), and fluid contamination level.

Q: Could you explain decoupling (demagnetization)? Is it usable as a safety measure?
A: Decoupling occurs when the pump load and motor torque surpass the magnetic coupling's torque capacity, causing noise. Upon decoupling, the motor should be halted immediately for troubleshooting to ensure safety.

Q: How can we adjust the flow rate?
A: In positive displacement pumps, altering motor speed is the simplest method to adjust flow. There's a nearly direct linear relationship between speed and flow.

Q: What is the starting capability of a micro gear pump?
A: Starting capacity varies between pumps, influenced by multiple factors such as fluid viscosity, line size, steam pressure, speed, and whether the pump starts wet or dry.

Q: What entails internal leakage in gear pumps?
A: Internal leakage refers to fluid from the pressure side returning to the inlet via gear gaps, affecting efficiency. This issue is prevalent in all gear pumps, though precision micro gear pumps experience less leakage. Low-viscosity fluids traverse gaps more easily; thus, these pumps are more efficient with thicker or viscous fluids.

Q: What defines cavitation in the context of gear pumps?
A: Cavitation involves the formation of vapor cavities ('bubbles' or 'voids') due to the inlet pipe's diameter being smaller than the pump's flow capacity. These cavities are influenced by fluid dynamics and pump system properties (available pressure, temperature, pump speed). Cavitation can lead to increased noise and premature pump wear.

Q: How do I identify Jonsn pump?
A: Each pump from Jonsn proudly bears our distinct LOGO and a precision laser code on its end face. This code encompasses vital information including the date of manufacture, product code, and unique serial number (S/N). With this S/N, you can effortlessly trace the original configuration sheet and access comprehensive test records, ensuring authenticity and quality assurance.
