🔹Product Overview
K5V140DT / K5V140DTP Hydraulic Main Pump is core power component for large‑size excavator hydraulic system, compatible with Hyundai R305‑7, R305LC‑9, R300‑9, R320LC‑7 and Doosan DX300 excavator models. This variable displacement piston pump converts engine mechanical power into high‑pressure hydraulic oil flow, supplying power for boom, arm, bucket, swing and travel movements of excavator. It resolves common equipment malfunctions including weak digging force, slow action speed, high hydraulic oil temperature, pump internal noise and pressure loss caused by piston wear, valve plate abrasion and internal leakage. Fully assembled and performance‑tested according to OEM specification for excavator hydraulic system replacement and overhaul.
