At the heart of the Kayaba PSVD2-21 Hydraulic Main Pump is its rotating group, a set of essential components responsible for converting mechanical power into hydraulic power.


The rotating group consists of various parts such as the cylinder block, piston shoes, swash plate, and valve plate. These components work in tandem to ensure smooth and efficient hydraulic fluid flow within the system.

The cylinder block, a key element in the rotating group, houses pistons that reciprocate as the pump operates. These pistons are in constant contact with the swash plate, a slanted component that controls the piston stroke and, consequently, the flow of hydraulic fluid. The valve plate regulates the fluid's direction, ensuring it flows in the desired path to execute specific excavator movements.

Regular maintenance and timely repair of the Kayaba PSVD2-21 Hydraulic Main Pump are essential to ensure its optimal performance. Over time, wear and tear can occur in the rotating group, leading to a decrease in efficiency and potential malfunctions. When the rotating group experiences issues, it may result in reduced hydraulic power, increased noise during operation, and even complete pump failure.

During the repair service of the Kayaba PSVD2-21 Hydraulic Main Pump, it is crucial to use genuine spare parts to maintain the pump's integrity and performance.


Genuine spare parts are designed to meet the exact specifications and quality standards set by the manufacturer, ensuring compatibility and reliability. Using substandard or non-original parts can compromise the pump's efficiency and longevity.

The repair process typically involves disassembling the pump, inspecting each component of the rotating group for wear or damage, and replacing any faulty parts with genuine spare parts.
