OEM HITACHI EX200-2-3 SERIES ENGINE WATER PUMP | Tonkee®

The water pump for the Hitachi EX200-2-3 Series is designed with durability and efficiency in mind.

It typically features a rugged cast iron or aluminum housing that houses the pump impeller, bearings, and a shaft. The impeller is a crucial part of the water pump responsible for creating the necessary flow of coolant.

Compatibility:
This water pump is specifically designed for the Hitachi EX200-2-3 Series of construction and excavator machines. It's essential to ensure that the water pump is compatible with the engine model and year of manufacture to guarantee proper fit and function.

Functionality:
The primary function of the engine water pump is to circulate coolant throughout the engine and associated components. It achieves this by being connected to the engine via a pulley and serpentine belt. When the engine runs, the belt turns the water pump pulley, which, in turn, drives the impeller. As the impeller spins, it draws coolant from the engine and forces it through the radiator, where it releases heat. The cooled coolant is then circulated back into the engine to regulate its temperature.

Cooling System Efficiency:
Efficient cooling is crucial for the optimal performance and longevity of the engine.

The water pump plays a pivotal role in maintaining the engine's operating temperature within the recommended range. Overheating can lead to engine damage and decreased efficiency, making the water pump's reliability paramount.

Maintenance and Replacement:
Like all mechanical components, the engine water pump may require periodic maintenance or replacement. Common signs of a failing water pump include coolant leaks, unusual noises (such as grinding or squeaking), and engine overheating. Regular inspection and maintenance of the water pump are essential to prevent potential breakdowns and costly repairs.

Materials and Quality:
The materials used in the construction of the water pump are of high quality to ensure longevity and reliable performance. Bearings and seals are typically designed to withstand the demanding conditions of construction equipment operation.

Installation:
Proper installation of the water pump is critical to ensure its effectiveness and longevity. It must be correctly aligned with the engine and connected to the cooling system hoses. Gaskets and seals must also be installed correctly to prevent coolant leaks.
