Belt-Drive vs. Direct-Drive Power Washer

When selecting a pressure washer, the drive is among the most important factors to consider. One concern most customers have is whether to buy a belt-drive or a direct-drive power washer. Here we explain the difference between these drives and the pros and cons of each. Follow through!

Direct Drive Power Washers

Direct drive pumps have a hollow shaft that is directly interconnected to the drive of an engine or motor. This type of pump setup is the least expensive to produce and is commonly used in most pressure washers. The direct drive has a gasoline engine speed of about 3450 revolutions per minute. Since the engine or motor shaft is directly connected to the pump, the pump has the same RPM as the engine.

Electric motors usually have a direct drive pump speed of 1750 or 3450 RPM. The direct-drive pumps are perfect for more compact designed pressure washers. One disadvantage of these systems is that the pump will have a reduced life span since the pump spins using the engine’s same speed. Also, faster direct drives pressure washer pumps may be unable to draw water efficiently from a standing water source or a tank.

Belt-Drive Power Washers

A belt-drive pump has a ring or pulley driven by one or more belts mounted on the engine or motor. Thanks to the pulley system, the pump can turn at a lower RPM, typically 900-1400 RPM. The belt drive has a larger oil capacity that helps the pump operate much cooler than the direct drive pump.a

Advantages of Belt-Drive

• Lower RPM to draw water from a standing water source
• Longer lifespan
• Vibration absorption
• Low operating temperature

Disadvantages of Belt Drive

• Requires more maintenance
• Loss of efficiency
