Гидронасос Nachi PVD-00B-14P-5G3 для мини-экскаватора Kubota KX41-2VXC

KX41‑2VXC Hydraulic Pump for Kubota Excavator spare parts PVD‑00B‑14P‑5G3 Axial Piston pump Aftermarket

Product Overview

This aftermarket variable axial piston pump acts as the core hydraulic power source tailored for Kubota KX41‑2VXC compact mini excavator. It supplies pressurized hydraulic fluid to drive boom lifting, arm crowding, bucket breakout, crawler travel and upper‑structure slew movements. Widely applied in backyard renovation, municipal pipe laying, landscaping work and indoor demolition assignments. Mini excavators often operate under frequent cyclic load and short‑cycle working conditions. As operating hours accumulate, oil contamination and thermal fatigue will bring wear to cylinder block, piston shoe assemblies, valve plate and drive shaft. Typical failure signs include weak digging power, jerky combined actions, abnormal rattling noise from pump compartment, rapid hydraulic oil temperature rise and external seal seepage. Manufactured strictly referencing OEM dimensional standards and performance curves, this replacement pump supports direct drop‑in installation, helping equipment owners and repair workshops restore machine performance without the high expense of original factory components.

Core Advantages

1. Wear‑resistant friction pair for compact excavator tough site conditions
Key matching components such as cylinder block, piston shoes and valve plate adopt special alloy formula together with multi‑step thermal treatment. Fine surface grinding strictly controls internal fitting clearance, lowering internal leakage and flow fluctuation. Great anti‑cavitation capability allows stable running even when hydraulic fluid carries tiny impurity particles, effectively prolonging pump service life under muddy, high‑temperature construction environments.

2. Pre‑calibrated built‑in regulator for sensitive action response
Every finished pump goes through full load hydraulic bench test. Regulator pressure‑flow parameters are fine‑tuned to match original equipment standards. It can react quickly to load shifts during digging cycles, preventing slow movement and action lag which often trouble aged mini excavators. Stable output guarantees smooth coordination of multiple combined operations.

3. Strictly replicated mounting structure to cut maintenance downtime
Mounting flange, spline shaft size, oil port layout and regulator installation position are fully consistent with original parts. Service technicians can finish pump replacement directly without modifying pipelines or readjusting complex hydraulic settings. It effectively reduces machine stand‑still time for rental fleets and local repair shops, minimizing economic loss caused by equipment outage.

4. Robust housing and complete sealing protection system
Integral high‑density cast iron housing absorbs pressure impulse and vibration generated during frequent digging cycles. Complete premium‑grade sealing kits block high‑pressure oil outward leakage, meanwhile keep mud, sand and moisture outside the pump chamber, protecting internal precision parts from secondary abrasive damage.

5. Cost‑efficient maintenance choice for small‑size excavator operators
Genuine OEM pump comes with high purchase cost plus long order lead‑time. This aftermarket assembly delivers reliable overall performance at competitive pricing. It is an ideal spare‑part option for repair stores, equipment rental businesses and global mini excavator parts distributors.

Manufacturing & Quality Control

Our production line focuses on aftermarket hydraulic pump assemblies for Kubota small‑tonnage excavators. Full‑process quality supervision covers raw material incoming inspection, heat‑treatment hardness verification, key dimension detection, assembling check and finished‑product hydraulic bench test, including pressure holding, flow detection, noise check and cyclic load simulation. Only fully qualified units will proceed to packaging process. Completed pumps are coated with anti‑rust oil, wrapped by shock‑proof cushion material and packed in export fumigated wooden cases, avoiding scratch, deformation and rust during long‑haul sea‑land transportation. We support bulk wholesale, stable batch supply, small trial orders are acceptable for worldwide clients.

Frequently Asked Questions

Q1: What abnormal conditions indicate main pump inspection or replacement?
A: If your KX41‑2VXC mini excavator occurs insufficient digging force, sluggish compound movements, obvious abnormal noise near pump position, fast hydraulic oil overheating, or metal particles are spotted inside hydraulic filter element, hydraulic pressure test and pump disassembly inspection should be carried out timely.

Q2: Will this hydraulic pump fit other Kubota excavator models?
A: This assembly is purpose‑built for Kubota KX41‑2VXC. Mini excavator main pumps have big differences in displacement, spline size and internal structure. Please double‑check your original part number PVD‑00B‑14P‑5G3 before placing order to prevent installation mismatch.

Q3: What critical points need attention during installation work?
A: Thoroughly clean hydraulic tank, pipelines and oil cooler, fit brand‑new hydraulic oil and all filter elements. Keep assembling environment clean to stop contaminants entering pump inner cavity. After finishing installation, perform system air exhaust and low‑speed no‑load running test before putting the machine into formal construction work.

Q4: Warranty scope explanation
A: Our warranty covers defects caused by manufacturing process. Damage induced by contaminated hydraulic oil, improper installation, cavitation erosion and long‑time overload operation will not be included within warranty coverage. Please strictly follow Kubota official maintenance guidance during overhaul jobs.
