HPV145H-28A Hydraulic Pump For ZX350H-3 Excavator

To ensure perfect compatibility, please verify your excavator's serial number on the nameplate before ordering the HPV145H-28A pump. Relying only on the ZX350H-3 model risks fitment issues due to production variations. The serial number is key to a 100% match. This step prevents returns, extra shipping costs, and costly downtime, guaranteeing a successful replacement.

Before installing your new pump, ensuring hydraulic system cleanliness is critical. We highly recommend a thorough system check and replacing all hydraulic oil and filters. Contaminants from a worn-old pump remain in the system and can quickly damage the new unit. This preventive step is essential to protect your investment and ensure expected service life.

The first 50 hours of operation are the critical run-in period for your new pump. Avoid continuous extreme-load applications during this time. A gentle run-in allows internal components to properly seat and form an optimal seal. This significantly reduces early failure risk and ensures long-term reliability and durability for your pump.

Clean hydraulic fluid is your pump's "lifeline." Regularly check the oil level and condition (color, viscosity), and strictly follow the recommended change intervals using specified oil. Contaminated or degraded fluid causes accelerated internal wear and efficiency loss. This simple maintenance is the most cost-effective way to avoid future expensive repairs.
