How to maintain the hydraulic system of a towed concrete pump?
Sep 12, 2025
Hey there! As a supplier of towed concrete pumps, I've seen firsthand how crucial it is to keep the hydraulic system in top - notch condition. A well - maintained hydraulic system ensures that your towed concrete pump runs smoothly, boosts its lifespan, and saves you a ton of money on repairs in the long run. So, let's dive into how you can maintain the hydraulic system of a towed concrete pump.
Regular Fluid Checks
The hydraulic fluid is like the lifeblood of your towed concrete pump's hydraulic system. It transfers power, lubricates moving parts, and helps in dissipating heat. You need to check the fluid level regularly. Most towed concrete pumps have a sight glass or a dipstick that makes it easy to see the fluid level. If the level is low, you should add the recommended hydraulic fluid right away.
But it's not just about the quantity; the quality of the fluid matters too. Over time, the hydraulic fluid can get contaminated with dirt, debris, and water. These contaminants can cause wear and tear on the hydraulic components and even lead to system failure. You can use a fluid sampling kit to take a sample of the hydraulic fluid and send it to a lab for analysis. Based on the results, you can decide whether it's time to change the fluid.
It's generally a good idea to change the hydraulic fluid every 1000 - 2000 hours of operation, but this can vary depending on the manufacturer's recommendations. And when you're changing the fluid, make sure to use the type of fluid specified in the pump's manual. Using the wrong fluid can cause compatibility issues and damage the system.
Filter Maintenance
Filters play a vital role in keeping the hydraulic fluid clean. They trap contaminants and prevent them from circulating through the system. There are usually two main types of filters in a towed concrete pump's hydraulic system: suction filters and return filters.
The suction filter is located on the suction line of the hydraulic pump. Its job is to prevent large particles from entering the pump. If the suction filter gets clogged, it can cause cavitation in the pump, which is a serious problem that can damage the pump impeller and reduce its efficiency. You should check the suction filter regularly and clean or replace it as needed.
The return filter is located on the return line of the hydraulic system. It captures contaminants that are generated during normal operation of the system. Like the suction filter, the return filter also needs to be checked and maintained regularly. A clogged return filter can increase the pressure in the system and cause damage to the components.
You can usually tell if a filter needs to be replaced by looking at the pressure differential across the filter. Most modern towed concrete pumps are equipped with a pressure gauge that shows the pressure differential. If the pressure differential exceeds the recommended value, it's time to replace the filter.
Seal and Hose Inspection
Seals and hoses are another important part of the hydraulic system. They prevent hydraulic fluid from leaking out of the system and ensure that the pressure is maintained. Over time, seals can wear out and hoses can develop cracks or leaks.
You should visually inspect the seals and hoses regularly for signs of damage. Look for any signs of leakage, such as wet spots or puddles of hydraulic fluid around the components. Check the hoses for cracks, bulges, or abrasions. If you notice any damage, you should replace the seals or hoses immediately.
When replacing seals and hoses, make sure to use high - quality parts that are compatible with your towed concrete pump. Using inferior parts can lead to premature failure and costly repairs.
Temperature Management
The hydraulic system of a towed concrete pump generates a lot of heat during operation. If the temperature of the hydraulic fluid gets too high, it can cause the fluid to break down, reduce its lubricating properties, and damage the components.
You need to monitor the temperature of the hydraulic fluid regularly. Most towed concrete pumps are equipped with a temperature gauge that shows the fluid temperature. If the temperature exceeds the recommended range, you need to take steps to cool down the system.
One way to cool down the hydraulic system is to use a cooler. A cooler is a device that transfers heat from the hydraulic fluid to the surrounding air or water. You should make sure that the cooler is clean and free of debris. A dirty cooler can reduce its efficiency and cause the hydraulic fluid to overheat.
Another thing you can do is to avoid overloading the towed concrete pump. Overloading the pump can cause the hydraulic system to work harder and generate more heat. Make sure to operate the pump within its rated capacity.
Component Lubrication
Proper lubrication is essential for the smooth operation of the hydraulic components. The hydraulic fluid itself provides some lubrication, but there are also some components that may require additional lubrication.
For example, the pivot points and bearings in the hydraulic system need to be lubricated regularly. You can use a grease gun to apply the appropriate grease to these components. Make sure to follow the manufacturer's recommendations regarding the type of grease and the lubrication intervals.
System Pressure Checks
The hydraulic system of a towed concrete pump operates at a specific pressure. If the pressure is too high or too low, it can cause problems with the system's performance and reliability.


You should use a pressure gauge to check the system pressure regularly. Compare the measured pressure with the recommended pressure values specified in the pump's manual. If the pressure is too high, it could be due to a clogged filter, a malfunctioning relief valve, or a problem with the pump. If the pressure is too low, it could be a sign of a leak or a worn - out pump.
If you find that the system pressure is not within the recommended range, you need to troubleshoot the problem and make the necessary repairs.
Training and Operator Awareness
Last but not least, proper training of the operators is crucial for the maintenance of the hydraulic system. Operators should be trained on how to operate the towed concrete pump correctly, how to perform basic maintenance tasks, and how to recognize the signs of potential problems.
They should also be aware of the importance of following the manufacturer's recommendations regarding maintenance schedules and procedures. A well - trained operator can help prevent many common hydraulic system problems and ensure that the pump operates efficiently.
