This is a hydraulic pump, the heart of the hydraulic system for Volvo excavators, specifically designed for the EC35 model. It generates the high-pressure flow of hydraulic fluid required to power all the machine's functions, such as digging, lifting, and steering. A worn or failing pump will result in a noticeable loss of power and speed in all hydraulic operations, making the machine sluggish and inefficient.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing hydraulic pump is a general sluggishness and loss of power across all hydraulic functions. As the pump degrades, these symptoms will worsen, leading to significantly reduced lifting capacity and slower cycle times. This can severely impact the machine's productivity and ability to perform its intended tasks.
Ensure the hydraulic reservoir is filled with the correct type and amount of hydraulic fluid before starting the engine. Avoid running the pump dry, as this can cause immediate damage.
It is essential to inspect and replace the hydraulic filter and check all hydraulic hoses and fittings for leaks or wear.
