18 Years Factory Flexible Motor Coupling - Cat 325c excavator hydraulic pump coupling flange – YNF

Product OverviewCoupling for Cat 325C

Are you looking for the cat 325c excavator hydraulic pump coupling flange? The flange coupling is used beteen the hydraulic pump and the engine. It transmisses the power from the engine to the hydraulic pump, thus driving the excavator to working.
There are several models of couplings that can be used on the model CAT 325C. But mostly used is the flange coupling.
From the CATERPILLAR SIS, you can see that the coupling flange is installed on the 244-8477: PUMP GP-MAIN HYDRAULIC.
Below is the drawing of the 244-8477: PUMP GP-MAIN HYDRAULIC.

Types of Couplings

At present, YNF Machinery provides the following types of couplings, which are suitable for different construction machinery.
H series coupling, replacing the CF-H coupling
A series coupling, replacing the CF-A coupling
Flange Coupling
S series coupling, can be used instead of SGF flexible coupling
CB series coupling, can be used instead of Bridgestone flexible coupling
TFC series coupling
Damper Series Couplings, which is widely used on the Komatsu excavators.
Clutch Series Couplings, which is widely used on the Komatsu excavators, Hyundai excavators, Liebherr excavators, Volvo excavatots, and so on.
Hose coupling series, for connecting the tube on the fuel tank and the outlet rubber hose
YC series coupling can be used instead of monolastic coupling
KY series coupling is a good substitute for Bowex Elastic coupling
GC series couplings are widely used in various types of air compressors and water pumps
Rubber block series coupling, suitable for the bulldozers
MH series coupling is a good substitute for rotex spider coupling
