Application scheme of industrial pump bearings

The Challenge of Modern Pump Systems

Modern society requires reliable and efficient pump systems. The challenge faced by pump maintenance personnel today is to find ways to reduce the total cost of ownership while complying with increasingly strict environmental and safety regulations.

Pump manufacturers are striving to increase the interval between failures while optimizing the energy consumption throughout the entire lifecycle of the pump, as energy accounts for 45% of the total cost of ownership of the pump.

Domestic bearing enterprises should closely cooperate with leading pump manufacturers and end-users, and propose targeted bearing design and application solutions.

Whether it's for municipal water supply, extracting oil from the seabed, or extracting corrosive liquids from chemical plants, we can design bearing products specifically to meet the product and service requirements of pump applications for bearings.

Water supply pump and drainage pump

Water and sewage pumps

Reducing the total cost of pumping stations is a key issue in the water supply and drainage industry. Energy consumption can account for 45% of the total cost of ownership of a pump.

In addition, water treatment and supply, as well as various food and beverage processing, rely on the application of reliable pumps, as any unplanned service shutdown could result in significant losses.

In many cases, industrial water pumps are located in remote and difficult to access areas, or are part of supply chains that require high reliability, making maintenance and service a real challenge.

Regardless of where the water pump system operates, bearing companies should provide application knowledge, solutions, and services for bearings to manufacturers and end-users in all fields of the industry. We have reduced the maintenance and extended the service life of submersible pumps and leak free pumps through energy-saving sealing of bearings, food compatible lubricants, condition monitoring, and lubrication free technology.

Industrial shaft seal

Optimization of Materials and Design in the Water Treatment Industry

The ability to withstand high flow rates and wear is crucial for pump applications in the water supply and drainage industry. The use of industrial shaft seals is aimed at meeting these requirements, helping to ensure optimal bearing uptime and functionality.

By optimizing material combinations and designs for the water supply and drainage industries, this type of seal improves sealing performance and increases pump flow and head.

Industrial shaft seals are compatible with both grease and oil lubricants, and can operate between -40 and 100 ℃, ensuring a long bearing service life, reliable operation, and minimal maintenance.

Chemical pump

Compliant with industry standards while reducing costs

If you run pumps that handle harsh, corrosive liquids, such as those used in the chemical industry, you will constantly face many challenges.

You not only need to comply with strict industry standards that involve safety and environmental regulations; To improve profitability, you also need to increase energy efficiency and reduce maintenance costs. Increase normal operating time and return on investment

There are various designs and materials among domestic bearing brands that are suitable for the chemical industry. A solution for medium lubrication pumps and pump efficiency audits can help you reduce maintenance costs while increasing the interval between failures.

By providing installation and alignment services, it helps to achieve longer bearing life and lower and smoother pump operation noise. As an additional line of defense, systems and services for status monitoring and process control can help you improve safety and reduce emissions.

Advanced bearings for subsea pumps and cryogenic pumps

Subsea screw pump

For the one-step process of extracting oil from the seabed at a depth of 3000 meters, the subsea screw pump is the preferred solution in the industry.

The bearing configuration of submarine screw pumps should be able to help reduce oil recovery time and improve oil recovery efficiency in deep-sea mining. Each screw is equipped with 2 CARB ring roller bearings to withstand shaft deflection and axial displacement. Four point contact ball bearings are used for axial positioning. Bearings can be made of special materials such as ceramic materials and special stainless steel, which are characterized by high nitrogen content and excellent fatigue and corrosion resistance.

Low temperature pump

Due to the extremely harsh operating conditions of cryogenic pumps, there is no doubt that their service life is usually only six months or less. However, some brands' low-temperature pump bearing designs are suitable for pumps that use various liquefied gases as lubricants. By using this solution, you can achieve over three times the lifespan of bearings and significantly extend the average maintenance interval.

This low-temperature pump solution can adopt a special heat-treated stainless steel variant, which has excellent anti-corrosion, wear-resistant, and fatigue protection performance. You can also try using hybrid bearings - deep groove ball bearings with ceramic rolling elements - combined with elastic, integral glass fiber reinforced PEEK cages.

PumPac pump bearings

PumPac angular contact ball bearing

The PumPac angular contact ball bearing assembly is paired with a 40 ° contact angle bearing that can withstand high axial loads and a 15 ° contact angle bearing that ensures safety when not under load. Its optimized internal design helps to reduce operating temperature and vibration, providing smoother operation and longer service life under harsh conditions. The PumPac configuration is highly suitable for centrifugal pumps and can be used for axial loads ranging from light to extremely heavy.

mud pump

Reliability under harsh conditions

Mud pumps are exposed to harsh conditions in remote and inaccessible areas, and are affected by cavitation, impeller wear, and corrosion. The reliability requirements for this type of pump are very high, as any premature failure can result in expensive production losses. However, due to their location in such harsh environments, performing maintenance may be complex.

Therefore, for mud pump operation and maintenance personnel, maximizing normal operating time is a challenging but crucial task.

Finding solutions to improve productivity

We can combine advanced system solutions for mud pumps with lubrication, status monitoring, and shaft alignment processes. Non lubrication technology and bearing solutions can achieve high pumping performance under extreme conditions, while reducing maintenance requirements and increasing the time between failures.

Mud pump solution

Reliability based system approach

For mud pumps, cavitation and abrasive wear of impellers pose a significant threat to normal operation and reliability. To address these challenges, mud pumps can provide a systematic approach that combines lubrication, condition monitoring, and shaft arrangement solutions.

Vibration and temperature monitoring, as well as alarm devices, can be installed during the installation process. Ultimately, the high-performance shaft configuration of this solution helps reduce imbalance and prevent cavitation impact.

Industrial shaft seal

Provide robust protection in harsh and remote environments

Mud pumps typically operate in harsh or worn environments. It is crucial to effectively prevent lubricant leakage and minimize the intrusion of pollutants. The industrial shaft seal of the mud pump provides these two functions, which help ensure optimal bearing normal operation time and functionality.

The shaft seal has an additional secondary lip that can eliminate contaminants without increasing friction. By combining optimized material combinations and designs, this feature improves sealing performance, as well as pump flow and head.

Industrial shaft seals are compatible with both grease and oil lubricants, and can operate between -40 and 100 ℃, ensuring longer bearing life, reliable operation, and less maintenance.
