ML Series Plum Elastic Motor Pump Coupling (ML1–ML13)

Product Description

The ML Series Plum Elastic Motor Pump Coupling (ML1–ML13) is a widely used plum jaw flexible coupling for power transmission between motors, engines and hydraulic pumps in construction machinery, industrial hydraulic stations and other Machine.

It consists of two cast/steel coupling hubs and a plum-shaped (plum blossom) elastic elastomer (plum cushion) installed between the claws. During operation, the plum elastic element absorbs shock and vibration, compensates small radial, angular and axial misalignment between the driving shaft and driven shaft. It effectively protects the hydraulic pump shaft and motor output shaft from damage caused by installation offset, impact load and frequent start-stop.

Covering full specifications from ML1 to ML13 with a wide torque range, this coupling is commonly adopted for motor-pump set connections. It is a popular replacement spare part for equipment overhaul and aftermarket maintenance of hydraulic systems.
