Complete technical documentation and global after-sales support for maintenance
Installation Method
Standard SAE / ISO 3019-1 mounting flange (SAE-A / SAE-B optional), compatible with standard pump mounting interfaces.
Multiple installation positions available: horizontal, shaft-up and shaft-down mounting; full oil filling and air bleeding required before commissioning for vertical installation.
Two connection modes: direct flange coupling connection or cardan shaft drive connection.
Through-drive design allows tandem mounting of secondary hydraulic pumps, flexible multi-pump assembly.
Hydraulic ports support inch thread or metric thread with O-ring sealing.
Shaft options: splined shaft, easy alignment and installation.

Application Range
Mini excavators, skid steer loaders, compact wheel loaders, self-propelled agricultural sprayers, aerial work platforms, municipal sanitation vehicles, auxiliary hydraulic circuits, fan drive systems and machine steering systems.
