The differential pressure between the inlet and outlet exceeds 25 bar, contingent on the medium's viscosity.
Q: What are the key considerations for pump installation, and what should be taken into account when designing the pump's piping system?
A: For optimal design, install the pump below the tank. Secure the motor base with screws and ensure positive pressure of the medium at the pump inlet, especially for viscous mediums with low fluidity. Given the micro gear pump's compact size, avoid any piping or instrumentation exerting pressure on the pump body.
Keep the inlet pipe as short as feasible, and ensure the inlet pipe is equipped with a filter to maintain pipe cleanliness, free from any particles.
Pipe diameter guidelines: For transporting viscous media, it is recommended that the pipe exceeds the pump inlet size, adhering to our company's selection software's recommended diameter. Occasionally, an inadequate inlet size may not satisfy flow requirements.

Should your application require operations beyond 80°C or involve other thermal considerations,we advise consulting with us. Factors like magnets, clearances, and motor bearings are pivotal for maintaining performance integrity.
Q: How does fluid viscosity impact the gear pump's performance?
A: Viscosity plays a crucial role; higher viscosity enhances volumetric efficiency and minimizes leakage, requiring reduced speeds to prevent overloading. Conversely, low-viscosity fluids increase internal leakage, impacting efficiency. As outlet pressure rises, internal leakage grows, diminishing volumetric efficiency. At consistent pressure, speed, and temperature, internal leakage and flow rate maintain a linear relationship. For further elaboration,please consult our factory experts for tailored guidance and support.
Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: When a gas/liquid mixture flows through a gear pump, it seamlessly navigates through without any disruptions. However, you may notice an increase in noise levels when gas enters the system. Additionally, there might be a temporary fluctuation in the pump's load, visible through changes in outlet pressure and the motor's power consumption.
Q: What are the minimum and maximum speeds allowed?
A: The provided data sheets detail the maximum speeds for each model, with specifications tailored for water as the operating medium. For more viscous substances, the maximum speed should be adjusted accordingly. The minimum operational speed is influenced by the motor's starting speed, flow rate, and internal leakage dynamics.
Q: Are Micro Gear Pumps FDA Approved?
A: Yes, these pumps can be manufactured with materials compliant with FDA standards.
Q: What is the recommended filtering level?
A: It is advisable to incorporate a 25-micron filter at the pump's inlet. Ensure the filter surface is ample to prevent pressure drops and to safeguard the pump's internal components.
Q: What affects pump and motor life?
A: Several factors influence the durability of pumps and motors. Critical considerations include the frequency of on/off cycles, operational speed, pressure load, and the cleanliness of the fluid.
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, causing the pump to become noisy. In such instances, it's essential to halt the motor immediately for troubleshooting and safety checks.
Q: How do we adjust flow rate?
A: Modifying the motor speed is the simplest approach to adjust the flow rate in positive displacement pumps, given the near-linear relationship between speed and flow.
Q: What is the starting capacity of the micro gear pump?
A: Starting capabilities vary between pumps and are influenced by factors such as fluid viscosity, pipe dimensions, vapor pressure, speed, and whether the pump is operationally wet or dry.
Q: What is internal leakage of gear pump?
A: Internal leakage in a gear pump refers to some fluid transferring back from the pressure side to the inlet side through gear gaps, impacting efficiency. While all gear pumps experience this, precision micro gear pumps exhibit minimal leakage, making them exceptionally efficient with thicker, viscous fluids.
Q: What is cavitation?
A: Cavitation involves the emergence of vapor cavities ('bubbles' or 'voids') in the liquid, often due to an inlet pipe diameter smaller than the pump's flow rate. Influenced by fluid characteristics and pump system properties (pressure, temperature, speed), cavitation can lead to noise and accelerated wear on the pump.
Q: How do I identify Jonsn pump?
A: Each pump is marked with a distinctive LOGO and laser code on its end face, detailing the manufacturing date, product code, and serial number (S/N). The original configuration and test records are accessible via this S/N code.
