Kyotechs Hitachi Hydraulic Pump Pressure Specs & Benefits
Kyotechs Hitachi Hydraulic Pump — Pressure Specs & Practical Value
Kyotechs, established in 2009, delivers high-quality excavator parts including Hitachi hydraulic pumps. Our pumps are designed to meet demanding jobsite needs while offering clear pressure specs, easy maintenance, and strong after-sales support.
Product Overview
Hitachi hydraulic pumps supplied by Kyotechs are rebuilt and new units tested to ensure consistent pressure control and smooth operation. They work across many Hitachi excavator models and are part of our one-stop hydraulic repair solution.
Key Pressure Specifications
- Typical operating (system) pressure: 24–35 MPa (240–350 bar) — suitable for most Hitachi medium to large excavators.
- Relief/maximum pressure setting: often set up to 35 MPa (350 bar) depending on model and application.
- Standby/idle pressure: usually lower and adjusted per machine to reduce wear and fuel use.
These ranges are representative; exact values depend on the specific Hitachi model and hydraulic circuit. Kyotechs verifies and adjusts pressure settings during installation and repair to match manufacturer recommendations.

FAQ
Why is it difficult to start an excavator in winter?
1.The climate is cold in winter, the ambient temperature is low, the viscosity of the engine oil increases, and the friction resistance of each moving part increases, which reduces the starting speed and makes it difficult to start.
2.The battery capacity decreases as the temperature drops, which further reduces the starting speed.
3.Due to the reduction in starting speed, the leakage of compressed air increases, and the heat dissipation of the cylinder wall increases, which greatly reduces the temperature and pressure of the air at the end of compression, and increases the delay period of diesel ignition. In severe cases, it may even fail to burn.
4.The viscosity of diesel at low temperatures increases, which reduces the injection speed. In addition, the swirl speed, temperature and pressure of the air at the end of compression are relatively low, which makes the atomization quality of the diesel injected into the cylinder poor, making it difficult to quickly form a good combustible gas with the air and ignite and burn in time, or even fail to ignite, resulting in difficulty in starting.
How to prevent hydraulic pump wear?
The way to prevent wear includes regular maintenance, using the right hydraulic oil, keeping the hydraulic system clean, and avoiding overload operation.
How to check and adjust the track tension?
Check the tightness of the track through the tensioner and adjust it if necessary to ensure the normal operation of the track.
What kind of battery is used in the excavator? Why?
The batteries we use are all lead-acid batteries for starting. Because this type of battery has the characteristics of large starting current and can meet the power supply requirements of the starter motor.
