What is the difference between direct drive and belt driven power washers?
Smaller, more portable pressure washers avoid the need for pulleys and belts by using a direct drive engine/pump assembly. The direct coupling means that the pump turns at the same RPM as the engine, typically 3450 or 1725 RPM as compared to belt driven pumps at 900 to 1400 RPM. This coupling exposes the pump to higher operational speeds, engine heat and excessive vibration which in turn means a shorter lifespan. The compact design and lower up front cost are a definite advantage, but direct drive pressure washers are designed for limited, infrequent usage such as that of a homeowner or weekend warrior. If the power washer is used more than once or twice a week for longer durations in an industrial or professional setting, a belt-driven machine is highly recommended. 5.
