The standard pump head system boasts a pressure resistance of 4MPa, and certain pump head systems are reinforced to handle up to 6MPa.
The pressure differential between the inlet and outlet surpasses 25bar, contingent on the fluid's viscosity.

Q: What critical factors should be considered for pump installation and when designing the piping system?
A: During design, installing the pump below the tank is ideal, securing the motor base with screws, and ensuring the medium's positive pressure is fed to the pump inlet, especially for high-viscosity mediums with inadequate fluidity. Due to the compact size of the micro gear pump, avoid exerting pressure on the pump body with piping or instrumentation.

The inlet pipe should be as short as possible, and you should equip the inlet pipe with a filter to maintain cleanliness and prevent particles.
Pipe diameter considerations: For viscous media transport, ensuring a larger pipe than the pump inlet is recommended. Follow our company's selection software's recommended pipe diameter, as a too-small inlet may hinder flow requirements.


Q: What types of chemicals can the micro gear pump convey?
A: Our pumps are crafted from varied materials, enabling compatibility with most fluids. Owing to the vast range of working In the realm of diverse working conditions and varied fluid dynamics, we strongly advocate for an initial test of the pump within the actual circuit conditions. This ensures optimal performance. Should your material involve potent substances such as dichloromethane, tetrahydrofuran, nitric acid, sulfuric acid, butyllithium, trimethylgallium, pyridine, liquid chlorine, dimethylacetamide, or similar media, we encourage you to contact us for advanced guidance and assistance. if conventional pump head cannot transport this media, we offer bespoke solutions tailored specifically to your working conditions for enhanced adaptability.

Q: Can the pump be used for metering?
A: Indeed, all our pumps are crafted as positive displacement units, ideal for metering applications.

Q: How does viscosity affect gear pump and system performance?
A: High viscosity materials can enhance the pump's volumetric efficiency and minimize leakage. However, speed adjustments are necessary to avoid overloading based on viscosity levels. Conversely, low-viscosity fluids may lead to increased internal leakage, especially as outlet pressure rises, reducing volumetric efficiency. When pressure, speed, and medium temperature remain steady, internal leakage and flow rate maintain a linear relationship. Please consult our factory experts for precise and tailored details.

Q: What happens when a gas and liquid mixture is pumped through a gear pump?
A: When a gas and liquid mixture is guided through the exceptional MRV Fair price precision gear pump, rest assured it navigates smoothly without any issues. However, you might notice a slight increase in noise levels as the gas traverses. During this phase, a temporary adjustment in the pump's load may occur, manifesting as mild fluctuations in the outlet pressure and the motor's power consumption.

Q: What are the minimum and maximum speeds allowed?
A: For precise information, refer to the data sheet specific to each model, which outlines the maximum speed parameters based on water as the medium. as medium. For fluids of higher viscosity, it is necessary to reduce the maximum speed appropriately. The minimum speed is primarily dictated by factors such as motor start-up speed control, desired flow rate, and internal leakage considerations.

Q: Are Micro Gear Pumps FDA Approved?
A: Yes, these pumps are available with materials that meet FDA compliance, ensuring they are suitable for applications requiring such standards.

Q: What is the recommended filtering level?
A: We recommend installing a 25-micron filter at the pump's inlet. Ensure the filter has a sufficiently large surface area to prevent pressure drops and effectively safeguard the pump's internal components.

Q: What affects pump and motor life?
A: Several crucial factors influence the longevity of both pump and motor. Central considerations include the frequency of on/off cycles, operational speed, applied 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's load and motor's torque exceed the magnetic coupling's capacity, causing the magnetic drive pump to disengage with a noticeable noise. It serves as a safety alert, prompting an immediate motor shutdown for troubleshooting.

Q: How do we adjust flow rate?
A: With positive displacement pumps, adjusting the flow is straightforward-simply modify the motor's speed. This alteration results in a nearly linear relationship between speed and flow.

Q: What is the starting capacity of the micro gear pump?
A: Starting capabilities vary across different pumps, hinging on factors like fluid viscosity, line dimensions, vapor pressure, speed, and the operational state, whether wet or dry.

Q: What is internal leakage of gear pump?
A: Internal leakage refers to fluid on the high-pressure side seeping back through gear gaps to the inlet, impacting efficiency. This is a common challenge across all gear pumps. Precision micro gear pumps, however, exhibit significantly reduced leakage, especially enhancing efficiency when handling thicker or more viscous fluids.

Q: What is cavitation?
A: Cavitation involves the creation of vapor cavities ('bubbles' or 'voids') within the liquid, typically due to an inlet pipe diameter that is inadequate for the pump's flow rate. These cavities arise from the interaction of fluid and pump system properties like available pressure, temperature, and pump speed. Cavitation is often accompanied by noise and can lead to premature pump wear.

Q: How do I identify Jonsn pump?
A: Each Jonsn pump is marked with a distinctive LOGO and laser code on its end face. These identifiers provide essential details such as the manufacturing date, product code, and serial number (S/N). The original configuration sheet and test records are easily traceable via the S/N code.
