Proper maintenance of pump bearings is essential to ensure long-term performance and reduce the risk of failure. Here are some key tips for effective pump bearing protection: 1. **New Water Pumps**: When first used, it's recommended to replace the lubricant (grease or oil) after 100 hours of operation. After that, it should be replaced every 500 hours to maintain optimal performance. 2. **Lubrication Practices**: Use high-quality grease for smooth bearings. After running for 1,500 hours, the grease should be changed. The amount of grease added must be appropriate—too much or too little can cause overheating. The bearing chamber should be filled to about 1/2 to 2/3 of its capacity. 3. **Grease Application**: Always add the lubricant in the correct orientation to ensure even distribution and proper coverage on the bearing surfaces. 4. **Storage Conditions**: Store the lubricant in clean, sealed containers to prevent contamination from dust, metal shavings, or other foreign particles that could damage the bearings. 5. **Grease Selection**: Sodium-based grease is commonly used for motor bearings due to its heat resistance (up to 125°C). However, it tends to dissolve in water, making it unsuitable for use in water pump bearings where moisture exposure is common. Maintaining your pump bearings properly not only extends their lifespan but also improves overall system efficiency and reduces downtime. Always follow manufacturer guidelines and use high-quality lubricants designed for the specific application.

Rotor Pump With Water-proff Cover

We are a world-leading technology-based enterprise focus on R&D and manufactures non-Newtonian fluid conveying equipment. We specialize in rotary pumps, homogeneous pumps and grinding pumps. We have obtained 11 invention Patents and 46 practical patents, and won many national honorary titles.


Twin-rotor lobe pump are multi-functional and bi-directional positive displacement pumps, produced with fine technology. These products use synchronic rotors, driven by a pair of synchronic gears in the gear box. Transmitted by the main shaft and the sub-shaft. The rotors move synchronically in counter-clockwise a directions, which, consequently, varies the pump capacity and builds up high vacuum capacity and emission pressure. It is particularly suitable to pump sanitary medium, high-corrosive and high-viscous medium.


Rotor pump with water-proff cover: The pump is equipped with a detachable protective cover for the whole machine, and the material is S.S., it can protect the motor, coupling and other parts from corrosion during on-site cleaning.


In the past 30 years, we dedicate to provide the scientific and professional solutions in fluid field. In the field of complex fluid transportation, our company's R&D technology, manufacturing technology, application technology is at the leading position in the world.


Durrex pumps can be widely used in food, consumer chemical, refined chemical, paper making, chemical fiber, pharmaceuticals, coating, etc. We will continue to focus on scientific research and innovation, improve the level of precision manufacturing, and continuously promote the intelligent development of fluid transportation industry, to create greater value for global users
