Advantages of ULP ULP18.5 (150 mm × 100 mm) Process Pumps
The clearance between the impeller and the front protection plate of the clearance adjustment mechanism can be adjusted from the outside without disassembling the pump, so the time for replacing the impeller can be relatively short.
Labyrinth seal The lubricating oil is sealed by a non-contact labyrinth seal with the main shaft, which can prevent oil leakage from the bearing without wearing the main shaft.
Diversity of shaft seals The seal chamber is separated from the pump casing, making it easy to handle various mechanical seals.
The three-part pump casing structure allows for easy disassembly and assembly of the pump without removing the outlet pipe from the pump casing, significantly reducing maintenance time.
The unique hydraulic design of the impeller enables the pump to perform at a high efficiency and promote the reduction of operating costs.

Safety Instructions and Preventive Maintenance Guide
Requirements for use
Pumps play a significant role in a variety of industries and applications, ensuring the smooth movement of liquids and gases. However, in order to maintain top performance and safety, it is essential to adhere to routine maintenance procedures and safety recommendations. This guide aims at providing the detailed information about pump safety and preventive maintenance.
Safety Instructions
1. Read the Manual
Before using EBara pumps, read and understand the handbook thoroughly. Make sure you understand the pump’s specifications, capabilities, and safety precautions.
2. Proper Installation
Ensure the pump is put appropriately according to the guidelines. Improper installation can cause operating inefficiencies and safety issues.
3. Ventilation
Operate pumps in well-ventilated areas to prevent the buildup of potentially harmful gases or vapors. If working in confined spaces, use proper ventilation equipment.
4. Emergency Shutdown Procedures
Familiarize yourself with emergency shutdown procedures in case of malfunction, leakage, or any other hazardous situation. Ensure all personnel know how to operate emergency shutdown mechanisms.
5. Regular Inspections
Conduct routine inspections of the pump and its components for signs of wear, damage, or leaks. Address any issues promptly to prevent accidents or system failures.
6. Chemical Compatibility
If handling hazardous chemicals, ensure the pump materials are compatible with the fluid being pumped or refer our chemical compatibility chart for more information. Incompatible materials can lead to corrosion, leaks, or chemical reactions.
Preventive Maintenance
1. Regular Lubrication
Keep bearings, seals, and other moving parts properly lubricated. Insufficient lubrication can lead to premature wear and breakdowns.
2. Inspect Seals and Gaskets
Check seals and gaskets for wear, damage, or leaks regularly. Replace any worn or damaged seals to prevent fluid leakage and maintain pump efficiency.
3. Check Motor Alignment
Ensure the pump motor is properly aligned with the pump shaft to prevent excessive wear on bearings and seals. Misalignment can lead to premature failure and costly repairs.
4. Replace Worn Parts
Keep an inventory of spare parts and replace worn or damaged components as needed. Regularly check wear parts such as impellers, seals, and bearings for signs of deterioration.
5. Schedule Maintenance
Develop a preventive maintenance schedule based on manufacturer recommendations and operating conditions. Regular maintenance helps prevent unexpected breakdowns and extends the life of the pump.
6. Document Maintenance Records
Keep detailed records of all maintenance activities, including inspections, repairs, and replacements. This information helps track the pump’s performance over time and identify any recurring issues.
By following these safety instructions and preventive maintenance practices, you can ensure the safe operation and longevity of your pumps while minimizing the risk of accidents or downtime. Remember, prioritizing safety and proactive maintenance is key to maximizing pump efficiency and reliability.
