A: Our conventional pump heads exhibit impressive resilience, resisting temperatures from -20°C to 80°C, with customizations available for extreme conditions ranging from a frigid -60°C to a scorching 160°C.
The conventional pump head system withstands pressures up to 4MPa, while certain systems endure up to 6MPa.
Handling impressive pressure differentials, the pump maintains a difference of over 25bar between the inlet and outlet, 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: During design, optimal installation involves positioning the pump beneath the tank. Secure the motor base using screws, ensuring the positive pressure of the medium is directed into the pump inlet, especially for viscous mediums with poor fluidity. Given the compact nature of our micro gear pump, ensure that piping or instrumentation does not exert pressure against the pump body.

Minimize the length of the inlet pipe, and the inlet pipe should be equipped with a filter to maintain pipe cleanliness and prevent particle contamination.
Pipe Diameter Requirements: For the best performance in transporting viscous media, it is essential that the piping be larger than the pump's inlet size. Adhering to the recommended pipe diameter from Jonsn's proprietary selection software is crucial. If the inlet size is insufficient, the desired flow cannot be achieved.


Q: What chemicals can the micro gear pump transport?
A: Our pumps are engineered with various materials to ensure compatibility with a wide range of fluids. Given the extensive variety of working conditions and fluid types, we strongly advise conducting thorough testing of the pump within your system's specific parameters. For fluids containing dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, and similar substances, contact us, if standard pump configurations cannot successfully transport these substances, we offer bespoke solutions tailored to your operational needs.

Q: Can the pump be used for metering?
A: Absolutely, our positive displacement pumps are ideally suited for precise metering tasks. The accuracy and consistency of delivery are influenced by the pump driver/control system and fluid properties, maintaining delivery precision within +/-0.5%. Reach out to us for further information.

Q: Which motors can be used?
A: Jonsn provides a diverse selection of drive types, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor.

Q: How can we decide the input power of the pump?
A: Jonsn's expert team can determine the optimal input power by evaluating your working conditions and the specific characteristics of the fluid being handled.


Q: What is the noise value of the pump?
A: The noise level is influenced by several factors, including installation, motor speed, and fluid characteristics. Typically, our gear pumps operate at a reference noise level of 55 dB at a distance of 1 meter, with a pressure differential of 3 bar and a speed of 3000 rpm.

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

Q: Can the pump be reversed?
A: While we supply the pump with the standard flow direction indicated by an arrow, it is designed to be reversible, allowing operation in both flow directions if needed.

Q: Can the pump run dry?
A: Our PEEK-modified and post-treated gears and bushings offer superior resistance to wear during dry operation. A video demonstrating our dry-run capabilities is available. Nonetheless, dry running should be minimized to prolong pump life.

Q: Is the pump self-priming?
A: Yes, our pumps boast self-priming capabilities. Please refer to the detailed specifications in our datasheet.

Q: What is the operating temperature of the pump and motor?
A: Our conventional pump heads function efficiently within a temperature range of -20 ~ 80°C. Please consult us if the application temperature exceeds 80°C or for other specialized temperature requirements, as factors like magnet strength, clearances, and motor bearings must be evaluated.

Q: How does viscosity affect gear pump and system performance?
A: When dealing with viscous materials, expect an increase in volumetric efficiency and a reduction in gear pump leakage. Adjusting for viscosity is key; higher viscosity necessitates a reduction in speed to prevent overload. Conversely, low-viscosity fluids can result in greater internal leakage, and as outlet pressure escalates, so does internal leakage, leading to a decline in volumetric efficiency. Remarkably, if pressure, speed, and medium temperature remain steady, internal leakage and flow rate maintain a linear relationship. Please consult factory for detailed specifications.

Q: What is the impact of pumping a gas and liquid mixture through a gear pump?
A: A gear pump can handle a gas/liquid mixture seamlessly. While it may sound noisier when gas is present, expect momentary effects on load, visible as fluctuations in outlet pressure and the motor's power consumption.

Q: What are the permissible speed limits for operation?
A: Each model's datasheet provides the maximum speed, which is generally calibrated for water as the medium. For more viscous fluids, speed should be decreased. The minimum speed depends on motor start speed control, flow rate, and internal leakage.

Q: Do Micro Gear Pumps meet FDA standards?
A: Yes, pumps crafted with FDA-compliant materials are available.

Q: What level of filtration is recommended?
A: A 25-micron filter at the pump's inlet is advisable, with a sufficiently large filter surface to prevent pressure drops and safeguard the pump's internal components.

Q: Which factors influence the longevity of pumps and motors?
A: Service life hinges on numerous elements, notably the frequency of on/off cycles, operating speed, load (pressure), and fluid contamination.

Q: What is decoupling in magnetic drive pumps, and can it serve as a safety measure?
A: Decoupling occurs when the pump's load and motor's torque capacity outweigh the magnetic coupling's torque capacity, causing noise and operational halts. Immediate motor cessation is necessary for troubleshooting.

Q: How is flow rateadjusted?
A: For positive displacement pumps, modifying the motor speed is the simplest method to adjust flow, given the near-linear correlation between speed and flow.

Q: What defines the starting capacity of a micro gear pump?
A: Starting capability varies significantly per pump model and is influenced by fluid viscosity, line size, steam pressure, speed, and whether the pump operates wet or dry.

Q: Could you elaborate on internal leakage in gear pumps?
A: Internal leakage refers to fluid returning from the pressure side to the inlet side via gear gaps, impacting efficiency. While typical in all gear pumps, precision micro gear pumps experience reduced internal leakage, with low-viscosity fluids traversing small gaps more easily, thus enhancing efficiency in thicker or more viscous fluids.

Q: What does cavitation mean?
A: Cavitation involves vapor cavity formation ("bubbles" or "voids") due to an inlet pipe smaller than the pump's flow capacity. Originating from fluid and pump system properties (pressure, temperature, speed), cavitation is known for noise and can lead to premature pump wear.

Q: How do I identify Jonsn pump?
A: Each pump is graced with our distinct LOGO and a precise laser code on the end face. This includes vital details such as the date of manufacture, product code, and serial number (S/N). You can effortlessly trace the original configuration sheet and test records using the S/N code, ensuring complete confidence in the product's authenticity.
