A: Our conventional pump heads are designed to withstand temperatures from -20°C to 80°C, with customization options available for temperatures as low as -60°C and as high as 160°C.
The standard pump head system boasts a pressure resistance of 4MPa, with certain models supporting up to 6MPa.
The differential pressure between the inlet and outlet exceeds 25bar, contingent on the viscosity.
Q: What considerations should be taken into account during the pump installation? What factors are crucial in designing the pump's piping system?
A: For optimal performance, install the pump below the tank, securing the motor base with screws. Ensure the medium's positive pressure is directed at the pump inlet, particularly for viscous media with poor fluidity. Given the compact nature of the micro gear pump, avoid any piping or instrumentation exerting pressure on the pump body.
Keep the inlet pipe as short as feasible, and ensure it is equipped with a filter to maintain a clean, particle-free system.
Pipe diameter guidance: For viscous media transport, it's advisable to use a pipe larger than the pump inlet size. Follow the pipe diameter specifications recommended by our company's selection software. In some instances, the inlet may be too small to fulfill flow requirements.
Q: Which chemicals are suitable for transportation using the micro gear pump?
A: Our pumps are crafted from diverse materials, ensuring compatibility with a vast array of fluids. With such a wide spectrum of working conditions and fluid types, it is strongly advised to test the pump in the actual circuit conditions it will face. Should your media include substances like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, or dimethylacetamide, it's essential to contact us, if a conventional pump head is unable to transport these media.We can design bespoke solutions tailored to your specific working conditions.
Q: Can the pump be used for metering?
A: Absolutely, all of our pumps are positive displacement pumps, ideally suited for precise metering applications. The accuracy and repeatability hinge on the chosen pump driver/control system and the fluid's properties. Delivery precision can achieve an impressive +/-0.5%. For further details, please contact us.

Q: What is the noise value of the pump?
A: Noise levels vary depending on the installation, motor speed, and fluid type. Our gear pump has a reference noise level of 55 dB at a distance of 1 meter, with a pressure difference of 3 bar and a speed of 3000 rpm, ensuring a quieter operation.
Q: Can liquids containing solid particles be transported?
A: Gear pumps are not suitable for transporting media with solid particles.
Q: Can the pump be reversed?
A: The factory standard is to mark the preferred flow direction with an arrow. However, the pump can operate in both directions if necessary.
Q: Can the pump run dry?
A: Our gears and bushings are crafted from PEEK, enhanced and post-treated for extraordinary dry wear resistance. You can watch our dry run test video for more insights. However, to preserve the pump's longevity, dry running should be kept to a minimum.
Q: Is the pump self-priming?
A: Indeed, our pumps are self-priming. For more detailed information, please refer to our datasheet.
Q: What is the operating temperature of the pump and motor?
A: Our standard pump heads are designed to function efficiently within a temperature range of -20 to 80°C. Please consult us if the temperature exceeds 80°C or falls outside this range, as additional factors such as magnets, clearances, and motor bearings require consideration.
Q: How does viscosity affect gear pump and system performance?
A: Handling viscous materials can significantly enhance the volumetric efficiency of the pump, while also minimizing gear pump leakage. However, it is crucial to adjust the speed accordingly, depending on the viscosity, to prevent any potential overloading. On the other hand, when dealing with low-viscosity fluids, there is a tendency for increased internal leakage. As the outlet pressure rises, this leakage intensifies, thereby reducing volumetric efficiency. Remarkably, when pressure, speed, and medium temperature are maintained consistently, the internal leakage rate remains stable, ensuring a linear relationship between the flow rate and these factors. Please consult factory for detailed specifications and guidance.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: The gas/liquid mixture effortlessly traverses the pump without any hindrance. However, as gas permeates the pump, it may result in a noisier operation. Additionally, there will be a momentary alteration in the load on the pump, which manifests as fluctuations in both the outlet pressure and the power consumed by the motor.
Q: What are the minimum and maximum speeds allowed?
A: The data sheet for each model clearly specifies the maximum speed, although these parameters are derived from water as the reference medium. When dealing with viscous fluids, it is essential to adjust the speed appropriately. The maximum speed needs to be reduced. Meanwhile, determining the minimum speed requires consideration of the motor's starting speed control, flow rate, and factors influencing internal leakage.
Q: Are Micro Gear Pumps FDA Approved?
A: We offer pumps crafted with materials that comply with FDA standards, ensuring safety and reliability.
Q: What is the recommended filtering level?
A: To safeguard the pump's internal components, it is advisable to install a 25-micron filter at the pump's inlet. Ensure this filter has a sufficiently large surface area to prevent pressure drops, thus protecting the pump's integrity.
Q: What affects pump and motor life?
A: Several factors can impact the service life of the pump and motor. Key considerations include the frequency of on/off cycles, operating speed, load (pressure), and potential fluid contamination.
Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump load and motor torque exceed the magnetic coupling's capacity, leading to a noisy magnetic drive pump. If decoupling happens, it is crucial to immediately stop the motor and troubleshoot the issue to prevent damage.
Q: How do we adjust flow rate?
A: For positive displacement pumps, the simplest method to modulate the flow rate is by varying the motor speed. This adjustment creates an almost linear relationship between speed and flow, offering precise control.
Q: What is the starting capacity of the micro gear pump?
A: The starting capacity of micro gear pumps is variable, influenced by several factors such as fluid viscosity, line size, steam pressure, speed, and whether the pump is operating in wet or dry conditions.
Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to a scenario where a portion of the fluid from the pressure side leaks back to the inlet side through the gear gaps, impacting efficiency. While internal leakage is a challenge for all gear pumps, precision micro gear pumps exhibit relatively minor leakage. These pumps are especially efficient with thicker or more viscous fluids as low-viscosity fluids can navigate these small gaps more easily.
Q: What is cavitation?
A: Cavitation describes the phenomenon where vapor cavities, often called 'bubbles' or 'voids,' form within the liquid. This occurs when the inlet pipe diameter is insufficient for the pump's flow rate. These cavities are a product of the fluid's physical properties and the pump system's attributes (such as available pressure, temperature, and pump speed). Cavitation often results in noise and can lead to premature pump wear, necessitating careful system design.
Q: How do I identify Jonsn pump?
A: Each pump proudly showcases its distinct LOGO and laser-etched code on the end face. This detailed identification includes the date of manufacture, a unique product code, and a serial number (S/N). With the S/N code, you can effortlessly trace back to the original configuration sheet and meticulous test records.
