The K3V140 Is A Smaller Lower Power Pump

The Kawasaki K3V140 is unlikely to be the main hydraulic pump for an excavator due to its size and function. Here's why

Main Pump vs. Pilot Pump Excavators typically use two types of pumps:

Main Pump:This is a high-power pump that delivers the majority of the hydraulic flow for the excavator's digging, scooping, and lifting functions.

Pilot Pump:This is a smaller, lower-power pump that serves two purposes conserving energy during low-flow situations and powering the excavator's control system.

K3V140 Specifications:While I can't find publicly available specifications for the K3V140, the 140 in its name likely indicates a displacement size higher than the K3V112, which is commonly used as a pilot pump. This suggests the K3V140 is likely larger and designed for higher flow rates than a typical pilot pump.

Possible Applications for K3V140 in Excavators:

Secondary Auxiliary Pump:It's possible the K3V140 could be used as a secondary or auxiliary pump in some larger excavators for specific functions requiring moderate flow but not the extreme power of the main pump.

Aftermarket Replacement:In some cases, aftermarket parts suppliers might offer the K3V140 as a higher-flow alternative to the stock pilot pump for excavators with specific performance needs.
