This type of pressure washer utilizes a belt and pulley system to transfer power from the motor to the pump. This design contrasts with direct-drive models where the motor shaft is directly connected to the pump. A common example involves a gasoline engine powering a high-pressure water pump via a belt-driven system.
The belt-driven mechanism offers several advantages. It allows for a reduction in engine speed, resulting in less wear and tear on the pump and engine components, ultimately extending their lifespan. The reduced operational speed also contributes to quieter operation. Historically, this configuration has been prevalent in heavy-duty and commercial applications due to its robust and reliable nature. This approach to power transfer enhances the durability and overall performance, making it suitable for demanding tasks.
