183-8146 Hydraulic Main Pump Piston Pump For 312C 312CL 312D 315C Excavator

Hydraulic Piston Pump Introduction

The 183-8146 is the main hydraulic pump for excavators, primarily suitable for small excavators such as the 312C, 312CL, 312D, and 315C. As a core piston-type hydraulic pump, it provides a stable high-pressure oil source for the boom, stick, bucket, travel, and swing systems. It features high efficiency, stable pressure output, and a robust and durable structure, making it particularly suitable for heavy-duty applications and effectively improving equipment operating efficiency and precision. This pump is widely used in construction, engineering machinery maintenance, and other fields as an OEM standard part or a high-quality compatible component.

A piston pump is a positive displacement reciprocating pump that achieves liquid intake and discharge through the reciprocating linear motion of a plunger within a cylinder. This pump features high pressure capacity, precise flow rate, high metering accuracy, and good self-priming capability, making it particularly suitable for high-pressure, low-flow, and precision conveying applications. It is widely used in petrochemical high-pressure injection, high-pressure cleaning, water treatment reverse osmosis, hydraulic systems, and food and pharmaceutical metering.

Hydraulic Piston Pump Advantages

• High Efficiency and Stable Output: Utilizing an axial piston design, it provides a highly efficient and stable high-pressure oil source, reducing energy loss and improving the overall hydraulic system's response speed.

  
  

• Robust and Durable: The robust structure, constructed with high-strength materials and precision machining, offers strong impact and contamination resistance, making it suitable for long-term use under heavy loads and harsh conditions.

  
  

• Excellent Compatibility: Perfectly compatible with models such as 312C, 312CL, 312D, and 315C, with installation dimensions identical to the original, allowing for direct replacement without modification.

  
  

• Enhanced Operational Performance: Significantly improves the speed and accuracy of boom, stick, bucket, travel, and swing movements, shortening work cycle time and increasing productivity.

• Low Noise and High Reliability: Smooth operation and excellent sealing performance reduce leakage, extend pump life, and lower maintenance frequency.

Package

Normally, it is packaged in cardboard boxes and then shipped on pallets or wooden crates. Special requirements from customers can be discussed and negotiated.
