For pressure resistance, conventional pump head systems can withstand up to 4MPa, with specific systems going as high as 6MPa.
The pressure differential between inlet and outlet surpasses 25bar, contingent on viscosity.
Q: Which factors are crucial when installing the pump, and what should be considered while designing the pump's piping system?
A: During design, optimal pump installation is below the tank, with the motor base securely locked using screws. It is crucial to ensure positive pressure of the medium is directed to the pump inlet, especially for viscous media with poor fluidity. Given the compact size of the micro gear pump, avoid any piping or instrumentation exerting pressure on the pump body.
Keep the inlet pipe as short as possible, and equip it with a filter to ensure cleanliness and absence of particles. Ensure the inlet pipe fulfills the requirement of being equipped with a filter to maintain cleanliness.
For conveying viscous media, a pipe larger than the pump inlet size is recommended, adhering to the pipe diameter guidelines provided by our company's selection software. In some cases, the inlet may be too small to meet flow requirements.
Q: What range of chemicals can the micro gear pump transport with precision and reliability?
A: Our versatile pumps are engineered with a selection of robust materials, ensuring compatibility with a vast array of fluids. Given the diverse nature of operational conditions and fluid varieties, we highly recommend conducting preliminary tests within the intended circuit to reflect actual usage scenarios. Should your material include complex substances like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, or dimethylacetamide, please reach out to us. In the event conventional pump heads are unable to transport these challenging media,we are fully equipped to devise customized solutions tailored to specific working conditions.
Q: Is the pump suitable for precise metering applications?
A: Indeed, all our pumps function as positive displacement pumps ideal for metering purposes. The precision and repeatability of delivery are influenced by the chosen pump driver/control system and the fluid's properties, achieving an impressive delivery accuracy of +/-0.5%. For comprehensive details, please feel free to contact us.
Q: What variety of motors can be utilized with the pump?
A: JONSN provides an extensive array of drive options, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, catering to diverse application needs.
Q: How do we determine the necessary input power for the pump?
A: At JONSN, we expertly calculate the essential input power based on your specified operational requirements and fluid characteristics.
Q: What is the noise level of the pump during operation?
A: Noise levels can vary depending on pump installation, motor speed, and fluid type. Typically, our gear pump operates at a commendable reference level of 55 dB at a distance of 1 meter, under conditions of a 3 bar pressure differential and 3000 rpm speed.
Q: Are liquids with solid particles suitable for transportation?
A: Gear pumps are not designed to transport media containing solid particles, ensuring optimal performance and longevity.
Q: Is it possible to reverse the pump's flow direction?
A: While the factory standard marks the flow direction with an arrow, our pumps are engineered to operate efficiently in both directions, offering flexibility as needed.
Q: Can the pump operate without fluid (dry running)?
A: Our pumps, crafted with PEEK modified gears and bushings that undergo post-treatment, exhibit strong resistance to dry wear. While you can view our dry run test video, it is advisable to limit dry running to prolong the pump's service life.
Q: Is the pump self-priming for enhanced operational convenience?
A: Absolutely, detailed specifications can be found in our comprehensive datasheet..
Q: What are the maximum operating temperatures for the pump and motor?
A: Our conventional pump heads deliver reliable performance across a broad temperature range of -20°C to 80°C. Should your requirements exceed 80°C or involve other temperature thresholds,please consult us as factors such as magnets, clearances, and motor bearings require careful consideration.
Q: How does the viscosity of fluids impact the performance of the gear pump and the entire system?
A: When dealing with viscous materials, one can expect an enhancement in the volumetric efficiency of the pump, which concurrently reduces gear pump leakage. It's important to adjust the speed based on viscosity to avoid overloading. Conversely, a low-viscosity fluid can lead to increased internal leakage. This internal leakage tends to rise with outlet pressure, thereby diminishing volumetric efficiency. Remarkably, when pressure, speed, and medium temperature are constant, the internal leakage rate stabilizes, maintaining a consistent linear relationship with the flow rate. Please consult factory for details.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: Pumping a gas/liquid mixture through the gear pump presents no issues. However, the pump might become noisier when gas passes through. This can also lead to brief changes in load, noticeable through fluctuations in outlet pressure and motor power consumption.
Q: What are the minimum and maximum speeds allowed?
A: The technical data sheet of each model clearly states the maximum speed, typically based on water as as medium. However, for viscous fluids, it is essential to lower the maximum speed accordingly. The minimum speed is largely determined by factors such as motor starting speed control, flow rate, and internal leakage.
Q: Are Micro Gear Pumps FDA Approved?
A: Yes, pumps are available with materials that are FDA compliant, ensuring they meet high safety standards.
Q: What is the recommended filtering level?
A: To ensure optimal protection of the pump's internal components and prevention of pressure drop, it's advisable to install a 25-micron filter at the inlet, with a sufficiently large filter surface.
Q: What affects pump and motor life?
A: The longevity of both pump and motor is influenced by numerous factors, primarily the frequency 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 when the pump's load and the motor's torque capacity exceed the magnetic coupling's torque capacity, making the magnetic drive pump noisy. It's crucial to immediately halt the motor for troubleshooting when decoupling is detected.
Q: How do we adjust flow rate?
A: Adjusting the flow rate in positive displacement pumps is most straightforward by modifying the motor speed, given the almost linear relationship between speed and flow.
Q: What is the starting capacity of the micro gear pump?
A: The starting capacity varies among different pumps and is contingent upon several factors, including fluid viscosity, line size, steam pressure, operating speed, and whether the pump is running wet or dry.
Q: What is internal leakage of gear pump?
A: Internal leakage in gear pumps refers to the phenomenon where a portion of the fluid from the pressure side leaks back to the inlet side through the gear gap, impacting efficiency. While this is a common issue for all gear pumps, precision micro gear pumps experience relatively minor internal leakage. Low-viscosity fluids traverse these gaps more readily, making the pump more efficient with thicker or more viscous fluids.
Q: What is cavitation?
A: Cavitation involves the generation of vapor cavities ('bubbles' or 'voids') within the liquid, often due to an inlet pipe diameter smaller than the pump's flow rate. These cavities are influenced by the fluid and physical properties of the pump system, such as available pressure, temperature, and pump speed, leading to noise and accelerated pump wear.
Q: How do I identify Jonsn pump?
A: With meticulous attention to detail, each pump proudly displays the Jonsn brand, featuring both a distinctive LOGO and a precise laser-etched code on its end face. This unique identifier includes the date of manufacture, product code, and serial number (S/N), ensuring authenticity and traceability. By referencing the S/N code, you can effortlessly access the original configuration sheet and comprehensive test records, offering complete transparency and peace of mind.
