Excavator / Crane 3600 Rpm Hydraulic Closed Pump With 14 T 12/24 DP
The hydraulic closed pump in an excavator serves various important purposes. Here are the primary uses of
the hydraulic closed pump in an excavator:
1 Bucket and Arm Operation: The hydraulic closed pump provides power to control the movement of the
excavator's bucket and arm. It enables the operator to dig, scoop, and dump soil or other materials efficiently.
2 Boom Movement: The hydraulic closed pump is responsible for powering the movement of the excavator's boom.
It allows the operator to raise, lower, and extend the boom for reaching different digging depths and positions.
3 Swing Operation: The hydraulic closed pump drives the swing mechanism of the excavator, enabling it to rotate
horizontally. This functionality enables the excavator to cover a large area without changing the machine's position.
4 Traveling Function: The hydraulic closed pump plays a crucial role in the excavator's traveling function. It provides power to
the hydraulic motors or cylinders that drive the tracks or wheels, allowing the excavator to move forward, backward, and turn.
5 Auxiliary Attachments: Many excavators have hydraulic systems that power auxiliary attachments such as hydraulic breakers,
grapples, or augers. The hydraulic closed pump supplies the necessary hydraulic pressure and control for these attachments
to perform their specific tasks.
In summary, the hydraulic closed pump in an excavator is essential for controlling the bucket, arm, boom, swing,
and traveling functions of the machine. It enables efficient digging, lifting, and maneuvering capabilities, making
the excavator a versatile and powerful construction equipment.

Features:
-
- 1 Closed Circuit: The harvester closed hydraulic pump is designed with a closed circuit to ensure the
- circulation and supply of hydraulic fluid within the system, preventing the entry of external impurities.
-
- 2 High-pressure Output: It is capable of delivering high-pressure hydraulic fluid to meet the power
- and force requirements of the harvester hydraulic system.
-
- 3 Efficient Performance: The closed hydraulic pump operates with high efficiency, allowing for quick
- response and adjustment of the hydraulic system's pressure and flow rate.
-
- 4 Durable and Reliable: The pump is typically constructed with durable materials and advanced
- manufacturing techniques, providing excellent wear resistance and corrosion resistance for reliable
- long-term operation.
