Product Descriptio

This hydraulic main pump is specifically designed for use with Hyundai R210-7 and R215-7 excavators. It features a Kawasaki K3V112DT dual variable displacement piston structure and is a core powertrain component for 21-ton medium-sized excavators. Its high-pressure design provides ample bucket digging power, delivering robust digging and breaking capabilities. Combined actions are synchronized and smooth, with no noticeable lag during retraction and rotation.

1. The pump body is constructed from high-strength, one-piece cast steel. Internal plungers, distributor plates, and slippers are all precision-ground and made of wear-resistant alloy materials, ensuring stable high-pressure output and effectively reducing common malfunctions such as internal leakage, overheating, and weak operation.

2. The high-pressure design provides ample bucket digging power, delivering robust digging and breaking capabilities. Combined actions are synchronized and smooth, with no noticeable lag during retraction and rotation. An internal noise-reducing distribution structure ensures stable oil temperature control during continuous operation, preventing engine stalling due to overheating.

3. The core friction pair is resistant to impurities and wear, resulting in a longer service life when exposed to dirty hydraulic oil on construction sites; the single-sided electric control lift is highly responsive, and the operation of fine grooving and leveling is smooth.
