ST691 Sea Water Pump Rehlko-Kohler-Lombardini KDI2504 - ED0065845820-S

What it is for

The original Rehlko Kohler Lombardini ST691 sea water pump, part number ED0065845820-S, is a component of the cooling system for marine applications using KDI2504 engines. This version is identified by its Corteco seal, specified as part of the pump configuration.

The pump is designed to circulate seawater through the marine cooling circuit, helping remove the heat generated during engine operation. Proper water circulation is essential for maintaining heat exchange efficiency and preventing engine overheating.

The ST691 configuration with Corteco seal is intended for replacing the seawater pump in KDI2504 applications requiring this specific part number. The sealing system helps separate the water circuit from the pump's mechanical components, reducing the risk of leakage during operation.

Pump replacement may be necessary in the event of water leakage, internal wear, insufficient water circulation or mechanical damage. An efficient pump contributes to reliable cooling under the continuous operating conditions commonly found in marine engines.

This original spare part is also identified by short reference 6584582. Parts catalogues additionally list previous references ED0065845590-S and ED0065845710-S. Before ordering, verify the installed pump part number, engine serial number and cooling system configuration, as not all ST691 pump versions should be considered automatically interchangeable.
