Converter pump seal for Manitou MT12355S

The converter pump seal MAN109690 serves as a sealing component within the transmission system of the Manitou MT12355S. Its primary function is to contain hydraulic fluid or lubricant within the torque converter and pump assembly while preventing the ingress of external contaminants. By maintaining a tight seal around the rotating shaft, this component helps preserve the internal pressure and lubrication levels required for the transmission to function correctly.

This part is compatible with the Manitou MT12355S model. It is manufactured to specific dimensions of 49.2mm inner diameter, 68.3mm outer diameter, and 12.7mm thickness. These dimensions are critical for achieving the necessary interference fit to prevent fluid leakage during operation.

Seals of this type are used in heavy machinery to isolate rotating shafts from the surrounding environment. They utilize a flexible sealing lip that maintains contact with the shaft surface, creating a barrier that prevents fluid migration. Proper installation of this seal is necessary to avoid pressure loss in the torque converter, which can otherwise lead to transmission performance issues or overheating of internal components.
