A: Standard pump heads withstand temperatures ranging from -20°C to 80°C, with customization available for temperatures as low as -60°C and as high as 160°C.
The standard pump head system can endure pressures up to 4MPa, with certain systems capable of withstanding up to 6MPa.
The differential pressure between the inlet and outlet exceeds 25 bar, contingent on fluid viscosity.
Q: What factors are critical in the pump installation process, and what should be considered when designing the pump's piping system?
A: During design, the pump should ideally be installed beneath the tank, with the motor base firmly secured with screws, ensuring the medium's positive pressure feeds into the pump inlet, particularly for viscous media which are less fluid. Given the compact nature of the micro gear pump, ensure that no piping or instrumentation exerts pressure against the pump body.
The inlet pipe should be as short as feasible, equipped with a filter to maintain cleanliness and prevent particulates. The pipe diameter must align with our selection software's recommendations to accommodate viscous media, sometimes necessitating a larger diameter than the pump inlet size to fulfill flow requirements.
Pipe diameter considerations: For viscous media transport, the pipe should exceed the pump inlet size, adhering to our company's selection software guidelines. Occasionally, the inlet size may be insufficient for flow needs.
Q: What types of chemicals can be transported using the micro gear pump?
A: Our pumps come in a variety of materials, ensuring that a compatible option is available for most fluids. Given the extensive array of applications, In varying conditions and with diverse fluids, it is imperative to initially test the pump within the actual circuit conditions it will operate. Should your material include elements like dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar substances, we strongly advise reaching out to us for expert consultation. If the conventional pump head is inadequate to transport these challenging media,we offer bespoke solutions tailored to meet your specific operational needs.
Q: Can the pump be used for metering?
A: Absolutely, all our pumps are positive displacement pumps designed for precision metering applications. The accuracy and repeatability are contingent on the pump driver/control system employed and the nature of the fluid involved. With a potential delivery accuracy of +/-0.5%, we encourage you to contact us for comprehensive details.

A: We provide an extensive array of drive types, including DC Brushless, DC Brush, AC Inverter, Servo, Stepper Motor, and Air Motor, to suit diverse operational demands.
Q: How can we decide the input power of the pump?
A: At JONSN, we can expertly calculate the necessary input power based on your specific working requirements and fluid characteristics. Contact us for tailored calculations.
Q: What is the noise value of the pump?
A: The noise levels are influenced by the pump installation, motor speed, and fluid type, typically registering at 55 dB at 1 meter with a pressure difference of 3 bar and a speed of 3000 rpm.
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: While the standard flow direction is indicated by a factory-marked arrow, the pump is capable of running in both directions, providing flexibility in installation.
Q: Can the pump run dry?
A: Our gears and bushings, crafted from specially modified and post-treated PEEK, exhibit impressive resistance to dry wear. Although we provide a dry run test video, it is advisable to minimize dry running to prolong the pump's lifespan.
Q: Is the pump self-priming?
A: Yes, the pump is self-priming. For further technical specifications, 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 optimally within a temperature range of -20°C to 80°C. Please consult us if operating conditions exceed 80°C, as factors like magnets, clearances, and motor bearings must be assessed.
Q: How does viscosity affect gear pump and system performance?
A: Viscous fluids can enhance the pump's volumetric efficiency and minimize internal leakage. However, adjustments in speed might be necessary based on viscosity to avert overloading. Conversely, low-viscosity fluids may increase internal leakage, thereby reducing volumetric efficiency as outlet pressure rises. With constant pressure, speed, and temperature, leakage remains steady, maintaining a linear flow rate relationship. Please consult our factory for in-depth insights.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: As the gas/liquid mixture navigates through the gear pump, it does so seamlessly. Although the presence of gas may amplify the noise levels, it is a normal occurrence. This transition will temporarily alter the load on the pump, which is observable through fluctuations in outlet pressure and the power consumed by the motor.
Q: What are the minimum and maximum speeds allowed?
A: The specific data sheet for each model will dictate the maximum speed, tailored to water medium. as For viscous fluids, the advised maximum speed should be decreased. The minimum speed is primarily influenced by motor starting speed control, flow rate, and internal leakage considerations.
Q: Are Micro Gear Pumps FDA Approved?
A: Yes, pumps are crafted with materials that comply with FDA standards, ensuring safety and quality.
Q: What is the recommended filtering level?
A: It is highly recommended to install a 25-micron filter at the pump's inlet. Ensure the filter surface is ample to prevent pressure drops and safeguard the pump's internal components.
Q: What affects pump and motor life?
A: Numerous factors impact service longevity. Critical elements include the frequency of on/off cycles, operational speed, load (pressure), and fluid contamination levels.
Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs when the pump's load and motor torque surpass the magnetic coupling's capacity, resulting in a noisy magnetic drive pump. If decoupling happens, immediately stop the motor for troubleshooting.
Q: How do we adjust flow rate?
A: Adjusting flow in positive displacement pumps is straightforward; simply modulate the motor speed. The relationship between speed and flow is nearly linear.
Q: What is the starting capacity of the micro gear pump?
A: Starting capabilities vary by pump and depend on factors such as fluid viscosity, line dimensions, steam pressure, speed, and whether the pump operates wet or dry.
Q: What is internal leakage of gear pump?
A: Internal leakage in gear pumps refers to fluid from the pressure side leaking back to the inlet side through gear gaps, impacting efficiency. Although a common issue for gear pumps, precision micro gear pumps experience less leakage, making them more efficient with viscous fluids.
Q: What is cavitation?
A: Cavitation involves the formation of vapor cavities ('bubbles' or 'voids') in liquid, typically due to a smaller inlet pipe diameter than the pump's flow rate. Influenced by the pump system's fluid and physical properties, cavitation can cause noise and hasten pump wear.
Q: How do I identify Jonsn pump?
A: Each pump is distinctly marked with a LOGO and laser-etched code on its end face. These markings display the manufacturing date, product code, and serial number (S/N). The S/N code allows you to trace the original configuration sheet and test records.
