Hydraulic Pump 708-1W-00741 for Komatsu

Product Overview

708-1W-00741 hydraulic pump is OEM interchange main hydraulic power component exclusively designed for Komatsu WA380-6 and WA430-6 wheel loaders.

As the core power supply unit of loader hydraulic system, this variable piston pump provides stable high-pressure oil flow for bucket lifting, tilt and steering hydraulic circuits. It adopts advanced variable displacement control structure, automatically adjusts output flow according to machine load, which effectively reduces energy consumption and avoids pressure fluctuation during heavy loading, stockpiling and earthmoving work.

Product Highlights

✅ Automatic Variable Displacement Energy-Saving Control

Built-in load sensing variable control valve adjusts pump output flow in real time based on working load, maintaining stable hydraulic pressure while lowering unnecessary power loss, effectively reducing loader fuel consumption during continuous operation.

✅ 100% OEM Matching Plug-and-Play Installation

All mounting hole layout, oil port caliber and spline drive shaft dimension fully follow Komatsu original standards. No cutting, drilling or hydraulic pipeline modification needed, complete on-site replacement within 30 minutes to cut machine downtime and maintenance labor cost.

✅ High-Rigidity Anti-Vibration Pump Body Structure

Integral alloy cast iron pump shell with thickened pressure-resistant wall, excellent impact and vibration resistance to adapt to harsh quarry, mine and construction site environments, effectively avoiding pump shell deformation and internal leakage.

✅ Multi-Layer Composite High-Temperature Sealing System

Adopts imported fluorine rubber oil seals, wear-resistant valve plate and anti-dust gaskets, stable sealing performance within -20℃ ~ +98℃ hydraulic oil temperature range, completely solve oil leakage failure of old pumps.

✅ Triple Strict Factory Performance Inspection

Each hydraulic pump passes static pressure holding leakage test, rated flow linearity test and full-load continuous aging test, all defective products are eliminated to greatly lower after-sales maintenance rate.

✅ Dual Supply Options: Brand New & Remanufactured Pumps

Two versions available to fit different customer budget demands. Remanufactured pumps retain intact original pump housing while all vulnerable internal pistons, valve plates, bearings and seals are replaced with brand-new precision accessories, with performance close to OEM new pumps at competitive price.

✅ Specialized Compatibility For WA380-6 & WA430-6 Loaders

Perfectly matched hydraulic power source for Komatsu WA380-6 and WA430-6 wheel loaders, single pump assembly covers two mainstream loader models, convenient for spare parts inventory management of repair stores.

✅ Low Vibration & Low Noise Stable Operation

Internal piston assembly adopts precision grinding and dynamic balance treatment, effectively reduce running vibration and mechanical noise, extend service life of matched hydraulic cylinders, valves and pipelines.

✅ Prolong Overall Hydraulic System Service Life

Stable pressure and flow output reduce impact wear of peripheral hydraulic components, lower long-term machine maintenance frequency and spare parts replacement cost for construction fleets.

✅ Complete Global After-Sales Warranty & Flexible Shipping

One year global quality warranty for non-artificial damage. Multiple shipping solutions including sea freight, air freight and international express are supported, mass stock enables fast 1-3 working days shipment after payment, tiered wholesale discount available for bulk orders.
