▌Product Overview
The Cummins K38 Sea Water Pump 5493046 is a replacement cooling system component designed for Cummins K38 and K50 diesel engine applications.
The sea water pump, also known as a raw water pump, is used in marine engine cooling systems to circulate external water through the cooling circuit. It supports heat transfer during engine operation and helps maintain stable operating conditions for the diesel engine.
Identified by Part Number 5493046, this Cummins Sea Water Pump is supplied as an individual replacement component for engine repair, maintenance, and overhaul projects. It is associated with reference numbers 3393018, 4314820, and 4314522, which can be used when confirming replacement requirements.
For marine diesel engines such as the Cummins K38 and K50, the cooling system relies on proper water circulation to remove heat generated during operation. When the original sea water pump shows wear or requires replacement, selecting the correct pump according to the engine model and part number helps maintain system compatibility.

▌Function of Cummins K38 Sea Water Pump 5493046
The Cummins K38 Sea Water Pump 5493046 plays an important role in the marine engine cooling system. Unlike a standard engine water pump that circulates internal coolant, a sea water pump handles external cooling water used for heat exchange.
The main functions include:
- Circulating seawater or raw water through the cooling system
- Supporting heat exchange during engine operation
- Helping maintain suitable engine operating temperature
- Providing continuous cooling flow for marine diesel applications
A properly operating sea water pump helps the engine cooling system work efficiently. During maintenance or overhaul, related components such as the impeller, seals, shaft, and pump housing may also be inspected depending on the pump condition.
▌Cummins K38 Sea Water Pump Applications
The Cummins K38 Sea Water Pump 5493046 is designed for marine applications using Cummins K38 and K50 diesel engines.
Common application areas include:
- Marine propulsion systems
- Commercial vessel engine systems
- Marine diesel engine maintenance projects
- Engine cooling system replacement
Because different marine engine configurations may use different cooling components, confirming the engine model and original part number is important when selecting a replacement sea water pump.
▌Related Cooling System Components
The sea water pump works together with other cooling system components to maintain proper engine temperature control.
Common related components include:
| Component | Function |
|---|---|
