Why Choose CHENHUI’s High Differential Pressure Micro Gear Pumps?
CHENHUI is your truested manufacturer and wholesale supplier of high differential pressure micro gear pumps. Our pumps are desined for long-term reliability and performance, and we provide custom options with low minimum order quantities tailored to meet the needs of various industries. CHENHUI ensures that every pump is produced to meet the standard, providing efficient and cost-effective solutions for your business.
- Magnetic Coupling Technology
The pump is driven by a magnetic field instead of a direct mechanical shaft. This means there are no dynamic seals, so there’s no risk of leakage. It also reduces wear, making the pump last longer. - Long Service Life
Built with high-quality materials and precision machining, our pumps resist wear even under continuous use. This reduces downtime and maintaince costs over time. - Wide Temperature Range
Most models operate within a temperature range of -30°C to 120°C, with some models designed to handle temperatures from -10°C to 90°C. This flexibility makes their performance stay stable and reliable. - Easy System Integration
Our gear pumps feature a compact design and small size, allowing them to fit into tight spaces. They are easy to install when integrating into existing equipment.
FAQs
1. What is the Maximum Pressure for a Gear Pump?
CHENHUI’s micro gear pump can handle a maximum system pressure of 40 bar. We also supply pumps designed for high differential pressure, up to 25 bar. Differential pressure is the key performance indicator for selecting the right gear pump. It shows how much resistance the pump can overcome when moving fluid through the system. A pump with higher differential pressure capability provides stable flow even under demanding conditions.
2. What is Differential Pressure in a Gear Pump?
Differential pressure is the difference between the outlet pressure and the inlet pressure of the pump. It tells you how much pressure the pump creates to move the fluid through the system. If the pump sucks fluid in at low pressure and pushes it out at high pressure, that difference is the differential pressure.
2. How to Increase Pressure in a Gear Pump?
To increase the pressure in a gear pump, you can take several approaches:
- Increase pump speed: Faster operation can result in higher pressure, but be cautious not to exceed the recommended RPM (rotations per minute).
- Adjust the relief valve: A properly set relief valve can help increase pressure by limiting the flow and ensuring higher pressure levels.
- Use a pump with a higher pressure rating: If you need a significant increase in pressure, it might be necessary to upgrade to a pump designed to handle higher pressures. Always ensure that the rest of the system components can handle the increased pressure to avoid damage.
3. What Are the Two Types of Gear Pumps?
There are two main types of gear pumps:
- External Gear Pumps: These pumps have two interlocking gears that transfer fluid. They are widely used in industrial applications for pumping oil, chemicals, and other liquids.
- Internal Gear Pumps: These pumps use one gear inside another. They are known for their smooth operation and ability to handle thicker fluids with high viscosity.
Both types are reliable but may vary in efficiency and suitability depending on the application.
4. Does a Gear Pump Need Priming?
Yes, gear pumps need to be primed before use, especially if the system has been idle or has air trapped inside. Priming ensures that the pump is filled with fluid to start the pumping process. Without priming, the pump could run dry, causing damage to the gears or even leading to pump failure. To prime a gear pump, you can manually fill it with the fluid or allow the pump to be self-priming if it is designed to do so.
