Doosan DX150 DX150LC Hydraulic Main Pump | 60100378‑J(12) Axial Piston Pump | Excavator Aftermarket Replacement Parts

Product Brief

This 60100378‑J(12) variable‑displacement axial piston main pump constitutes the core power source for the hydraulic system of Doosan DX150 and DX150LC crawler excavators. It converts engine mechanical power into high‑pressure hydraulic flow, driving digging, boom lifting, slewing, travel and all other operational movements of the machine. Widely deployed in municipal infrastructure renovation, residential lot grading, small‑scale quarry excavation and river silt clearance projects, this aftermarket pump satisfies component replacement and overhaul demands for equipment rental operators, on‑site repair garages and cross‑border spare‑part distributors across Africa, Southeast Asia and the Middle East.

Operating under sustained high‑pressure and frequently fluctuating load conditions, the main hydraulic pump is prone to cylinder block wear, valve plate scratching, internal piston shoe abrasion, pressure loss and hydraulic oil leakage. When failure occurs, the excavator will exhibit obvious symptoms including insufficient digging force, sluggish compound movements, excessive hydraulic oil temperature, irregular knocking noise from the pump housing and overall machine power drop. Unplanned pump breakdown will halt construction schedules and generate substantial emergency repair costs for project contractors and equipment asset owners.

Our aftermarket axial piston pump is manufactured to OEM‑equivalent standards for mounting footprint, oil port layout, spline dimension and system pressure parameters. No cutting or secondary modification is required during pump swap, supporting direct drop‑in installation and effectively cutting machine downtime. As a practical budget‑friendly substitute for high‑cost original pump assemblies with long lead‑times, this pump delivers stable hydraulic performance under factory wholesale pricing, perfectly suited for bulk purchasing by global construction machinery spare‑part suppliers.

Unique Product Competitive Advantages

1. Strict dimensional replication, purpose‑built for Doosan DX150 / DX150LC hydraulic system, non‑interchangeable with other excavator models
This axial piston pump is manufactured strictly according to original installation dimensions, oil port positions and pressure setting parameters of DX150 and DX150LC. Highly matched friction pairs greatly reduce internal leakage after installation. No adapter fittings or extra machining work are needed for assembly.
2. Premium internal friction pair components, enhanced durability for cyclic heavy‑duty site operations
Many low‑cost replacement pumps suffer rapid pressure decay and short service life due to inferior valve plate and piston shoe materials. Our critical internal components adopt standardized quenching and fine‑grinding processing to boost wear resistance. It maintains consistent output pressure under frequent load changes, helping rental fleets reduce overall pump replacement frequency.
3. Comprehensive factory‑level performance testing before shipment to avoid unexpected on‑site failure
Every finished hydraulic pump goes through factory pressure test, flow calibration and leakage inspection before packing. Defective units are filtered out in advance, preventing rework difficulties for maintenance teams and economic losses caused by sudden pump failure on construction sites.
4. Cost‑effective aftermarket solution to control equipment operating expenditure
Genuine OEM main hydraulic pumps carry high purchase price and lengthy delivery cycles. Our aftermarket pump delivers equivalent working pressure and service durability as OEM assemblies at factory direct price, lowering annual repair costs for enterprises managing multiple excavator units.
5. Flexible global logistics options for bulk wholesale clients
In‑stock products can be dispatched promptly upon payment confirmation. Air freight supports urgent breakdown repair orders; consolidated sea freight and full‑container shipment provide cost‑efficient bulk purchasing solutions for long‑term distributors.

Factory Production Strength

Our manufacturing facility focuses on R&D and production of aftermarket hydraulic main pumps, travel motors and swing motors for diverse excavator brands. We own a complete production workflow covering alloy steel forging, ultra‑precision grinding, professional heat‑treatment and finished‑product hydraulic bench testing. Dedicated hydraulic simulation test benches replicate harsh real‑world heavy‑load working conditions to continuously optimize component wear resistance and pressure stability. Our hydraulic assemblies are exported to numerous overseas markets and maintain long‑term stable partnerships with global construction machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this 60100378‑J(12) hydraulic main pump fit excavator models outside Doosan DX150 and DX150LC?
A1: Cross‑model installation is not supported. Different excavator models adopt main pumps with different mounting dimensions, oil‑port layout and pressure calibration. Please double‑verify your machine model and corresponding part number before placing orders.

Q2: What hydraulic faults can this main pump solve?
A2: It addresses malfunctions caused by worn pistons, scratched valve plate and internal component damage: weak digging power, slow machine movements, high hydraulic oil temperature, internal oil leakage and abnormal pump knocking noise.

Q3: Do you offer volume‑based preferential pricing for large‑quantity orders?
A3: Yes, tiered discount policies apply according to purchase volume. We can also arrange full‑container sea shipment to cut overall logistics expenses.

Q4: What packaging is used for long‑distance ocean‑going transportation?
A4: Anti‑rust oil is evenly coated over all metal surfaces. The whole pump is wrapped with waterproof and shock‑resistant PE film, then secured inside reinforced export plywood cases, to prevent collision deformation and moisture corrosion during long overseas transit.
