This type of pressure washer utilizes a belt and pulley system to transfer power from the motor to the pump. The motor spins a pulley connected to a belt, which in turn rotates a second pulley attached to the pump’s drive shaft. This mechanical configuration allows for a reduction in rotational speed while increasing torque, enabling the pump to generate the high pressure required for effective cleaning.
The use of a belt-driven system offers several advantages. The reduction in pump speed compared to the motor speed reduces wear and tear, potentially extending the pump’s lifespan. The belt also acts as a shock absorber, protecting both the motor and pump from sudden pressure changes and potential damage. Historically, this robust design has proven reliable and easily serviceable, contributing to its continued popularity in various applications.
