Excavator Pump Parts HITACHI HPV145, Hydraulic Pump Regulator EX300 | Partsdic®

The HPV145 hydraulic pump regulator is a vital component of the hydraulic system in excavators.


Its primary function is to regulate the hydraulic pressure generated by the hydraulic pump. This regulation is essential to ensure smooth and efficient operation of various hydraulic functions, such as boom and bucket movements, arm control, and other attachments.

Compatibility:
The HITACHI HPV145 regulator is designed specifically for use in HITACHI excavators, including models like the EX300. This ensures a precise fit and optimal performance when integrated into the hydraulic system of these machines.

Hydraulic Pressure Control:
The HPV145 regulator is responsible for maintaining the hydraulic pressure at the desired level. It accomplishes this by adjusting the pressure relief valve, which controls the flow of hydraulic fluid. This precise control is essential for preventing damage to the hydraulic system and ensuring the safety of the machine and operator.

Pressure Range:
The regulator is designed to handle a specific range of hydraulic pressures. The exact range may vary depending on the specific application and requirements of the excavator, but it typically falls within the specifications recommended by HITACHI for the EX300 and similar models.

Material and Durability:
These regulators are typically constructed from high-quality materials to withstand the demanding conditions of excavator operation.


Materials like hardened steel and corrosion-resistant alloys are commonly used to ensure durability and longevity.

Temperature Tolerance:
The HPV145 regulator is engineered to perform reliably in various temperature conditions. Excavators are often used in diverse environments, from freezing cold to scorching heat, and the regulator must maintain consistent performance throughout these extremes.

Maintenance and Service:
Regular maintenance of the hydraulic pump regulator is essential to ensure its continued performance. This may involve periodic inspections, cleaning, and replacement if necessary. Proper maintenance practices can extend the life of the regulator and prevent costly breakdowns.

Hydraulic System Efficiency:
Efficiency is a critical aspect of any hydraulic system in an excavator. The HPV145 regulator helps maintain the efficiency of the system by ensuring that hydraulic pressure is precisely controlled. This efficiency not only improves the excavator's performance but also reduces fuel consumption and overall operating costs.
