Hitachi HPV050 HPV102 HPV105 HPV116 HPV118 HPV135 Hydraulic Pump Parts

HYLINK supplies precision-engineered Hitachi HPV series hydraulic main pump parts and complete rotary group repair kits for heavy-duty mobile machinery. Every component is manufactured to original specifications, 100% interchangeable with genuine Hitachi parts, and fully tested before shipment — providing a reliable, cost-effective replacement solution for repair shops, distributors, and fleet maintenance teams worldwide.

Key Specifications

Product Overview

The Hitachi HPV series is a core hydraulic main pump platform extensively used across Hitachi EX and ZAXIS series mid-to-large excavators. Operating under continuous high-pressure cycles and heavy digging loads, the internal rotary group—including the cylinder block, pistons, valve plate, and swashplate—gradually wears down over time, causing symptoms such as hydraulic drift, slow cycle times, excessive operational noise, or loss of breakout force.

HYLINK manufactures complete rotary groups and individual replacement components for HPV050, HPV102, HPV105, HPV116, HPV118, and HPV135 pumps. Produced from high-strength forged alloy steel and wear-resistant bronze alloys, every part is CNC-machined to micron-level tolerance and verified via CMM inspection. This allows technicians to perform targeted component replacements rather than replacing the entire pump assembly, drastically reducing maintenance expenses and machine downtime.

Available Components

Below is the standard component list for Hitachi HPV series hydraulic pumps (HPV050 / HPV102 / HPV105 / HPV116 / HPV118 / HPV135). Individual spare parts and complete overhaul kits are both available:

Quality Assurance & Manufacturing

Every HYLINK pump and replacement part undergoes strict quality control before shipment:

l Dimensional accuracy — checked with high-precision CMM (Coordinate Measuring Machines) to guarantee an exact fit with original pump housings.

l Material metallurgy — manufactured from premium forged steel and high-wear-resistant alloys to prevent premature fatigue.

l 100% performance test — every complete pump assembly is tested on our dynamic hydraulic test rig for pressure, flow rate and efficiency under full working load.

Packing, Shipping & Warranty

l Packaging — anti-rust protective film + heavy-duty foam cushioning + standard export fumigation-free wooden case (reinforced carton for small spare parts).

l Shipping — express courier (DHL / FedEx) for urgent repair orders; sea or air cargo for bulk orders.

l Warranty — 6 months quality assurance against manufacturing and material defects from the delivery date. In the event of a confirmed quality defect, HYLINK provides hassle-free replacement.
