Three filters for concrete pump
The three filters of a concrete pump refer to the three key filter elements used on a concrete pump truck to filter and clean fluids in the system, which are.

Oil filter (oil filter):
The main function is to filter impurities, metal particles, sludge and other pollutants in the engine oil, ensure the cleanliness of the engine oil, and prevent these pollutants from causing wear and damage to engine components.
Installed in the engine's oil circulation system, as the oil flows, the filter intercepts and stores these pollutants, protecting the normal operation of the engine.

Air filter (air filter):
The main function is to filter out impurities such as dust and sand particles in the air entering the engine, preventing these impurities from entering the cylinder and mixing with fuel for combustion, thereby reducing engine wear and improving combustion efficiency.
Installed on the intake duct of the engine, it filters out impurities in the air through filter paper or filter cartridges, providing clean air for the engine.

Diesel Filter
For concrete pumps that use diesel as fuel, the diesel filter is a key component for filtering impurities in diesel.
It can remove moisture, impurities, and particulate matter from diesel, ensure the cleanliness of diesel, prevent these pollutants from blocking fuel injectors, damaging high-pressure fuel pumps and other components, and also help improve fuel combustion efficiency.
Diesel filters are usually installed in the diesel supply system to filter the diesel entering the engine.

In summary, the three filter of concrete pumps play a crucial role in the operation of concrete pump trucks. They jointly ensure the normal operation of the engine and hydraulic system, extend the service life of the equipment, and improve construction efficiency and quality. Therefore, in daily maintenance and upkeep, the three filters should be regularly inspected and replaced to ensure their filtration efficiency and service life.
