In the world of heavy machinery and industrial hydraulics, the hydraulic pump is the heart of every system. Whether it’s a Rexroth A4VSO71, Kawasaki K3V112, Linde HMF75, or Parker PVP140, every pump operates under extreme conditions. Over time, components such as valve plates, cylinder blocks, pistons, and seals wear out, reducing efficiency and risking costly downtime.
Halies Hydraulic specializes in manufacturing and supplying replacement spare parts for these major brands, providing high-quality, precision-engineered solutions for global customers.
1. Key Product Series and Applications
Rexroth Hydraulic Pumps
Models like A4VSO, A10VSO, and A2F are widely used in excavators, construction machinery, and hydraulic power units.
Halies offers interchangeable spare parts such as cylinder blocks, pistons, valve plates, and drive shafts. All parts undergo heat treatment and hardness inspection to ensure consistent performance and reliability.
Kawasaki Hydraulic Pumps
The K3V / K5V series are designed for high-pressure mobile applications. They are common in excavators, cranes, and marine equipment.
Halies provides compatible pistons, valve plates, and cylinder blocks for K3V63, K3V112, K5V140, and other models. Each part ensures stable pressure output and low noise operation.
Linde Hydraulic Pumps
The HMF / HPR series are used in mining and industrial machinery with continuous high-pressure requirements.
Halies produces precision spare parts with mirror-polished sealing surfaces to ensure zero leakage and long service intervals.
Parker and Eaton Hydraulic Pumps
The PVP / PAVC / 72400 series pumps are popular for compact designs and stable flow characteristics. Halies provides cost-effective replacements that match OEM dimensions and tolerances.
Other Series: LPVD / BPV / DPVP
Halies also supplies spare parts for LPVD, BPV, and DPVP series, covering a full range of piston, cylinder, and valve components.
2. Common Failures in Hydraulic Pumps
-
Pressure Instability – Caused by worn valve plates or leakage from control pistons.
-
Internal Leakage – Resulting from scored cylinder blocks or aged seals.
-
Noise and Vibration – Usually due to worn piston shoes or shaft misalignment.
-
Overheating – Caused by poor oil filtration and excessive internal friction.
-
Low Efficiency – Occurs when clearance between pistons and cylinders increases due to wear.
