The Hitachi ZAX70-5G is a mini excavator commonly used for small to medium-sized digging projects, landscaping, demolition, and other applications requiring a compact and maneuverable machine.
The ZAX70-5G uses a Kawasaki K3V series pump as its pilot pump. This is a common pilot pump used in various excavators due to its:
Low Cost: Gear pumps are a relatively inexpensive design.
Reliability: They have a simple design with few moving parts, making them dependable.
Low Pressure, High Volume: Gear pumps excel at delivering a consistent flow of fluid at moderate pressures, perfect for pilot pump applications.
The ZAX70-5G's main pump would be a separate, high-power pump that provides the majority of the hydraulic flow for the excavator's working functions. If you'd like to confirm the specific pumps used in your ZAX70-5G excavator, it's best to consult the user manual or parts catalog for your model or contact a Hebei Keluo Construction Machinery Co., Ltd.
