Pompe hydraulique Nachi PVD-00B-11-3-4732A pour mini-pelle Yanmar VIO10

VIO10 Hydraulic Pump for Yanmar Excavator spare parts PVD‑00B‑11‑3‑4732A Axial Piston pump OEM

Product Overview

The Yanmar VIO10 belongs to the smallest class of excavator — machines designed to fit through doorways, work inside buildings and carve out trenches in back gardens. What they lack in size, they make up in constant use: a micro excavator on a landscaping or indoor‑demolition contract works at full stretch hour after hour, and its hydraulic pump takes that workload through a remarkably small package. The PVD‑00B axial piston pump is exactly that component — the unit that turns engine power into the precise hydraulic flow driving the boom, bucket, tracks and zero‑tail swing. On machines this small, pump wear shows up as hesitant boom movement, sluggish track travel, a high whine from the pump housing, and hydraulic oil that warms quickly through short shifts. Because the machine works where noise and dirt cannot be contained easily, clean, quiet hydraulic performance matters more than on a standard‑size excavator. This OEM‑grade pump is built to the original PVD‑00B‑11‑3‑4732A specification, so a worn unit can be exchanged directly, restoring the controlled, responsive feel the VIO10 was built for.

Core Advantages

1. Compact‑scale precision for a tiny machine's demands
Pumps on micro excavators run at high relative pressures in very small housings. The PVD‑00B's piston, cylinder block and valve plate are finished to OEM tolerances, so the tiny flow rates stay accurate — boom and bucket movements stay controlled rather than jerky.

2. Quiet running for indoor and residential work
VIO10s work in occupied buildings and gardens where noise is a real constraint. Correct gear and piston clearances keep the pump note down, so the machine does not add a harsh new whine to an already noise‑sensitive job.

3. Responsive metering that matches the operator's controls
The regulator is set to the original pump mapping, so the pump responds the way the machine's joysticks expect. Fine control for careful digging next to walls or pipes is restored rather than exaggerated.

4. A direct fit that suits small‑machine service work
Micro excavators are serviced in cramped workshops and on site. The pump matches the original mounting and port layout, so removal and refitting follow the standard routine without fabrication or adapters.

5. OEM‑grade value for a machine class with high utilisation
Small excavators often clock high hours relative to their size. Fitting an OEM‑grade pump keeps the VIO10 productive for the long term, at a cost far below a Yanmar dealer exchange unit.

Manufacturing & Quality Control

Every pump is produced under controlled conditions: material verification, precision machining, surface hardening and clean assembly. Each completed unit is bench‑tested for pressure, flow and running noise before release, and only passing units are packed. The finished pump is preservation‑coated, sealed and cushioned in export‑standard packaging suitable for small parcels and long‑distance freight.

Frequently Asked Questions

Q1: How do I confirm this pump matches my VIO10?
A: Match the pump model on the existing unit (PVD‑00B‑11‑3‑4732A) and share your machine serial number. Micro‑machine variants can differ, so this check avoids a mismatch before dispatch.

Q2: What symptoms point to pump wear on a VIO10?
A: Hesitant boom or bucket movement, slow track travel, a high pump whine and quick oil warm‑up. If these appear, inspect the pump before contamination spreads through the small hydraulic circuit.

Q3: Should I change the hydraulic oil when fitting the new pump?
A: Yes — renew the oil and filter, and flush the small circuit as best you can. A clean circuit is the best protection for the new pump's precision surfaces.

Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage caused by contaminated oil, wrong fluid, foreign objects, overload or incorrect installation is excluded; please follow the Yanmar service manual for fitting.
