Komatsus Parts Gear Oil Pump Pilot Pump for Wa450 705-12-37010/7051237010/705-11-35010/7051135010
Products Description
WA450 Gear Pump | Heavy-Duty Fluid Power for Industrial & Mobile Applications
The WA450 is a robust, high-pressure gear pump engineered for demanding industrial and mobile machinery. Designed with precision-machined components and optimized for durability, it delivers reliable fluid transfer across wide pressure, temperature, and speed ranges-making it ideal for hydraulic systems, lubrication circuits, and power units requiring consistent performance under tough conditions.
Advantages
High-Pressure Capability: Rated for 280-320 bar (4060-4640 psi) with 350 bar (5075 psi) peak, outperforming standard gear pumps in heavy-load scenarios.
Wide Temperature Range: Operates reliably from -25°C to +125°C (-13°F to +257°F) with synthetic or mineral oils, suited for extreme environments.
Low Noise & Vibration: Helical gear profile and precision bearings reduce noise to ≤70 dB(A) at 1750 rpm, enhancing operator comfort.
Durable Construction: Reinforced cast iron housing and hardened alloy steel gears (HRC 58+) withstand shock loads and prolonged use.
Easy Integration: Compact footprint (170mm × 110mm × 130mm) and standard SAE mount compatibility simplify installation.

Highlights
Heavy-Load Reliability: Reinforced housing and hardened gears handle 350 bar peak pressures, ideal for hydraulic presses, construction equipment, and heavy machinery.
Efficient Flow: Precision helical gears minimize internal leakage, ensuring smooth flow with ≤±1.8% ripple at rated speed-critical for CNC machines and robotics.
Extreme Environment Ready: Synthetic seal options (FKM) resist chemical/oil degradation, while extended temperature range (-25°C to +125°C) suits Arctic or desert operations.
Low Maintenance: Modular design with quick-access covers allows fast gear/bearing replacement; standard wear parts are field-serviceable to reduce downtime.
Applications
Industrial Hydraulics: Powering cylinders, valves, and actuators in metal stamping, forging, and injection molding machines.
Mobile Machinery: Hydraulic systems for excavators, loaders, and crane lifts (WA450-HF recommended for high-force actuators).
Marine & Offshore: Hydraulic power units for winches, cranes, and deck machinery (corrosion-resistant seals available).
General Machinery: Lubrication circuits in machine tools (lathes, mills) and heavy-duty conveyor systems.
