Leistungsspezifikationen
Durchflussrate: There is no accurate official flow rate value. However, generally, the flow rate range of engine cooling water pumps is around 5 – 300 m³/h. This water pump should be within this range to meet the cooling requirements of the engine.
Head Pressure: Generally, the head range of engine cooling water pumps is 5 – 250 m, and the working pressure does not exceed 1.6 MPa. It can be inferred that the head pressure of this water pump is also within this range.
Physical Dimensions
Gewicht: The product weighs approximately 2.5 kg / 5.5 lbs or around 5.61 lbs.
Packaging Dimensions: Usually, it is about 8×8×8 inches or around 8.07×7.05×6.42 inches.
Materials and Construction
Pump Body Material: Metal materials such as aluminum and cast iron are usually used. For example, the water pump of the hirintol brand is made of aluminum and cast iron.
Impeller: It is generally made of wear – resistant and corrosion – resistant materials such as brass or engineering plastics to ensure reliability and stability under long – term high – speed rotation.
Shaft Seal: Wear – resistant mechanical seals are mostly used, which can effectively prevent coolant leakage and extend the service life of the water pump.
