A: Our conventional pump heads are engineered to function efficiently within a temperature range of -20 to 80°C. Please consult us if your operation conditions exceed 80°C or involve other temperature-related concerns. Considerations such as magnetism, clearances, and motor bearings may need adjustment.

Q: How does viscosity impact the performance of the gear pump and system?
A: Viscosity greatly influences pump efficiency. Higher viscosity enhances volumetric efficiency and reduces gear pump leakage, yet may require reduced speeds to prevent overloading. Conversely, low viscosity increases internal leakage. With constant outlet pressure, speed, and medium temperature, internal leakage remains steady, maintaining a linear flow rate relationship. Please consult our factory experts for more nuanced details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: When a dynamic gas/liquid mixture traverses the gear pump, it flows seamlessly through the system. However, the pump may emit more noise during the gas phase. Additionally, there can be temporary fluctuations in the pump's load, visible as variations in outlet pressure and motor power consumption.

Q: What are the minimum and maximum speeds allowed?
A: Each model's data sheet provides the maximum speed specifications, tailored specifically for water as the reference medium. However, for fluids with higher viscosity, a speed reduction is necessary. The minimum speed is primarily influenced by motor start-up speed control, flow rate, and internal leakage considerations.

Q: Are Micro Gear Pumps FDA Approved?
A: Indeed, we offer pumps constructed with FDA-compliant materials, ensuring safety and quality.

Q: What is the recommended filtering level?
A: It is advisable to integrate a 25-micron filter at the pump inlet. A filter with ample surface area helps prevent pressure drops and safeguards the pump's internal components.

Q: What affects pump and motor life?
A: Several elements influence the service life of pumps and motors. Crucial considerations include the frequency of on/off cycles, operational speed, load (pressure), and fluid cleanliness.

Q: What is decoupling (aka demagnetization)? Can this be used as a safety feature?
A: Decoupling occurs if the pump's load and the motor's torque capacity surpass the magnetic coupling's limits, resulting in a noisy magnetic drive pump. Immediate motor shutdown is essential for troubleshooting upon decoupling.

Q: How do we adjust flow rate?
A: In positive displacement pumps, the simplest method to modulate flow is by altering the motor speed, due to the near-linear relationship between speed and flow rate.

Q: What is the starting capacity of the micro gear pump?
A: The starting capacity varies across different pumps, hinging on factors such as fluid viscosity, line dimensions, steam pressure, operational speed, and the wet or dry status of the pump.

Q: What is internal leakage of gear pump?
A: Internal leakage in gear pumps occurs when fluid on the pressure side reverts to the inlet side through gear gaps, compromising efficiency. This leakage is universal in gear pumps but minimal in precision micro gear pumps, which perform optimally with thicker or more viscous fluids due to lower leakage in these conditions.

Q: What is cavitation?
A: Cavitation involves the formation of vapor cavities ('bubbles' or 'voids') within the liquid, typically caused when the inlet pipe diameter is insufficient for the pump's flow rate. Influenced by the fluid and pump system properties, including available pressure, temperature, and speed, cavitation contributes to noise and accelerates pump wear.

Q: How do I identify Jonsn pump?
A: Each Jonsn pump is distinctly marked with a LOGO and laser-etched code on its end face, detailing the manufacture date, product code, and serial number (S/N). The original configuration and test records are traceable via the S/N code.
