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

Pump manufacturers are working hard to increase the time between failures and optimize the energy consumption of the entire pump life cycle, as energy accounts for 45% of the total pump ownership cost.Shandong LIGZZ Bearing Co., Ltd

s 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 in chemical plants, we can design bearing products specifically to meet the product and service needs 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 stoppage can lead to significant losses.

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

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

Industrial shaft seal

Optimizing Materials and Design in the Water Treatment Industry

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

By optimizing the material combination and design for the water supply and drainage industry, this sealing element improves sealing performance and increases pump flow and head.

Industrial shaft seals are compatible with two types of lubricants, grease and oil, and can operate between -40 to 100 ℃, ensuring a longer bearing service life, reliable operation, and less maintenance.

Chemical pump

Meets industry standards while reducing costs

If you run pumps that handle harsh and 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 related to safety and environmental regulations; To improve profitability, you also need to improve energy efficiency and reduce maintenance costs. Increase uptime and return on investment

There are various designs and materials among domestic bearing brands, suitable for the chemical industry. A solution for auditing the efficiency of medium lubrication pumps and pumps 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 low-temperature pumps

Submarine screw pump

For the one-step process of oil extraction at a depth of 3000 meters, underwater screw pumps are the preferred solution in the industry.

The bearing configuration of the submarine screw pump 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 made of 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 low-temperature pumps, there is no doubt that their service life is usually only six months or shorter. However, some brands of low-temperature pump bearings are designed to be suitable for pumps that use various liquefied gases as lubricants. By using this solution, you can achieve over three times the service life of bearings and significantly extend the average maintenance interval.

This low-temperature pump solution can use a stainless steel variant that has undergone special heat treatment, which has excellent anti-corrosion, wear resistance, 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 set 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 very 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. This type of pump requires high reliability, as any premature failure can lead to expensive production losses. However, due to their harsh environment, performing maintenance can 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 re lubrication technology and bearing solutions can achieve high pumping performance under extreme conditions, while reducing maintenance requirements and increasing fault interval time.

Mud pump solution

A systematic approach to reliability

For mud pumps, cavitation and abrasive wear on the impeller 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 and alarms can be installed during the installation process. Ultimately, the high-performance shaft configuration of this solution helps to reduce imbalance and prevent cavitation impacts.

Industrial shaft seal

Provide sturdy protection for harsh and remote environments

Mud pumps typically operate in harsh or worn-out environments. It is crucial to effectively maintain 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 function.

The shaft seal has an additional second lip that can remove 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 two types of lubricants, grease and oil, and can operate between -40 to 100 ℃, ensuring a longer bearing operating life, reliable operation, and less maintenance.
