Kawasaki K3V112 Is Used As A Pilot Pump for Excavators And Other Construction Machinery

The Kawasaki K3V112 is a specific model of hydraulic gear pump commonly used as a pilot pump in excavators and other construction machinery.

Here's a breakdown of the K3V112 in the context of pilot pumps:

1.Function: Like any pilot pump, the K3V112 provides low-pressure, high-volume hydraulic fluid for two key purposes

2.Energy Efficiency: During low-flow situations, like when the excavator isn't doing heavy work, the K3V112 allows the main hydraulic pumps to shut down, saving fuel.

Pilot Control The K3V112 also supplies hydraulic fluid to the excavator's control system. This system uses pressure and flow to move the spools in the main hydraulic control valve. These spools then direct the high-pressure flow from the main pumps to the excavator's actuators (arm, bucket, tracks, etc.).

Gear Pump Design The K3V112 is a gear pump, a common choice for pilot pumps due to their.

Low Cost Gear pumps are a relatively inexpensive design.

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.

Based on information found online, the Kawasaki K3V112 pilot pump is compatible with various excavator models, including Kobelco SK200-3, SK200-5, SK200-6, SK200-8,Volvo EC210B, EC210, EC240.There are likely other excavators that use the K3V112 as well.
