III. Compatibility and Application Notes
1. Dedicated Compatibility
This pump is the factory-original main pump for Sany SR150/SR155 rotary drilling rigs. Material code 60114324 is Sany's internal standard part number, allowing direct replacement of original parts without modifying pipelines or installation interfaces.
2. Operational Matching
The K3V112 series is specifically designed for heavy-duty engineering machinery, capable of meeting the high-flow, high-pressure demands of composite operations such as rotation, pressure application, and hoisting on rotary drilling rigs, adapting to continuous working conditions of pile-driving machinery.
3. General Purpose Supplement
Pumps of the same model are also widely used in 20-25 ton excavators. However, versions with the "-9NG9-1EB" suffix are dedicated to rotary drilling rigs. Note the differences in control logic between excavator versions and rotary drilling rig versions.
