EX200‑1 EX200 Hydraulic Pump for Hitachi Excavator spare parts HPV116C Axial Piston pump

Product Overview

The Hitachi EX200 and its early EX200‑1 version represent an era of excavator design that owners still value — simple, rugged, hydraulics‑driven machines kept working long after newer models took the spotlight. The HPV116C axial piston pump is the heart of that older hydraulic system, and its design philosophy is as straightforward as the machine itself: no complex electronics, just hardened mechanical parts converting engine power into the flow that lifts, digs and travels. On a machine of this age, pump wear follows a predictable path — slow boom lift, weak bucket curl, travel that drags on flat ground, oil temperature creeping up after a couple of hours, and a growing mechanical note from the pump housing. What makes the HPV116C special is how well it wears in: older machines often stay in service with carefully maintained pumps long after their electrics would have retired a newer model. This aftermarket pump is built to the original geometry and hydro‑mechanical settings, so a worn unit can be exchanged directly and the classic EX200 kept earning.

Core Advantages

1. Renews a hard‑to‑source legacy component
HPV116C pumps for the early EX200 are increasingly difficult to find in good condition. This aftermarket unit keeps those classic machines running when original exchange supply has dried up — a practical supply line for owners of aging fleets.

2. Rugged hydro‑mechanical design, rebuilt to original standards
The old‑style regulator has no electronics to fail, and our aftermarket reproduction holds the same mechanical calibration. Pressure and flow behave as the machine's original circuits expect, without the complexity of modern control systems.

3. Hardened friction surfaces that suit long‑hour service
Piston shoes, cylinder block and valve plate are finished for durability. On machines that rarely see a workshop unless forced, wear‑resistant surfaces are what keep the pump producing between overhauls.

4. A direct fit for a machine that expects simple repairs
The flange, spline and port layout reproduce the original pump, so the work follows the old service manual without adapters or fabrication. Older machines were built to be fixed, and this pump honours that.

5. Economical repair choice for an already depreciated asset
An EX200 has long since finished its depreciation curve. Spending dealer prices on a new pump makes little sense; this aftermarket unit restores performance at a cost that fits the machine's current value.

Manufacturing & Quality Control

Each pump is produced under controlled conditions: material verification, precision machining, surface hardening and careful assembly. Completed units are bench‑tested for pressure, flow and running noise before release, with only passing units packed. Preservation treatment and shock‑absorbing export packing protect the pump during long‑distance transport, and sample orders are welcome for workshops testing the supply.

Frequently Asked Questions

Q1: Will this pump fit later EX200 variants like the ‑2 or ‑3?
A: It is specified for the EX200 and EX200‑1. Later variants can differ internally — please share the old pump tag or your machine serial number, and we will confirm compatibility before dispatch.

Q2: How is the regulator adjusted after fitting?
A: The pump ships pre‑set to the original calibration. If your system needs tuning, follow the pressures and procedures in the Hitachi service manual rather than improvising adjustments.

Q3: My old pump had a leaking seal — do I need anything else?
A: Renew the shaft seal and any hoses showing cracking while the pump is out. We can supply seal kits alongside the pump on request.

Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage from contaminated oil, foreign objects, overload or incorrect installation is excluded; a fresh oil and filter service on an older machine is strongly recommended.
