General Information
Model Number: U5MW0208
Compatible Engines: Perkins 1104D - 44, 1104D - 44T, 1104D - 44TA
Purpose: The water pump is designed to circulate coolant within the engine cooling system to maintain the engine's operating temperature within the optimal range.
2. Construction and Materials
Casing: It is usually made of high - quality cast iron or aluminum alloy. Cast iron provides durability and resistance to corrosion and wear. The aluminum alloy option, if used, offers a good balance between strength and light weight.
Impeller: The impeller is a crucial component and is typically made of a corrosion - resistant material such as brass or plastic - reinforced composite. The material choice ensures efficient water flow and resistance to damage from coolant chemicals.
3. Performance Specifications
Flow Rate: The water pump is designed to have a specific flow rate, which could be around [X] liters per minute (L/min) or gallons per minute (GPM). This flow rate is determined based on the engine's cooling requirements to effectively dissipate heat. For example, it might have a flow rate of 30 - 50 L/min depending on the engine's cooling demands.
Pressure: It can generate a certain pressure to ensure that the coolant is circulated through the entire cooling system, including the radiator, engine block, and hoses. The pressure might range from 1 - 2 bar (14.5 - 29 psi), enabling the coolant to reach all the necessary components and cool them efficiently.
4. Mounting and Installation
Mounting Bracket: The water pump comes with a mounting bracket that is designed to fit precisely onto the Perkins 1104D series engines. The bracket has bolt holes and a shape that matches the engine's mounting surface to ensure a secure and accurate installation.
Bolt Pattern: The bolt holes on the mounting bracket follow a specific pattern and have a standard diameter to match the engine's mounting points. For example, it might have a bolt pattern of [number of bolts] holes with a diameter of [X] mm and a bolt circle diameter of [Y] mm.
Shaft and Pulley: The pump shaft is designed to mate with the engine's drive pulley. The shaft diameter is typically [Z] mm and has a keyway or spline to ensure a positive drive connection. The pulley size is also specified to provide the correct rotational speed ratio for the water pump to operate effectively with the engine's speed.
5. Sealing and Gaskets
Seal Material: The water pump is equipped with high - quality seals to prevent coolant leakage. The seal material is usually a rubber compound such as nitrile rubber or Viton, which has excellent resistance to coolant chemicals, temperature, and pressure.
Gaskets: Gaskets are provided to ensure a leak - proof connection between the water pump and the engine block and other mating components. The gaskets are made of a suitable material like cork - rubber composite or a synthetic gasket material that can withstand the operating temperature and pressure of the cooling system.
6. Operating Temperature Range
The water pump is designed to operate effectively within a wide temperature range. It can typically handle coolant temperatures from - 20°C to 120°C (- 4°F to 248°F), which covers the normal operating range and some extreme conditions that the engine might encounter.
