Direct drive pressure washers are much more well direct than the belt drive model excuse the pun.
Direct drive vs belt drive pressure washer.
When a direct drive pump is mounted directly to the engine several factors will cause serious issues over time.
They are not worth the extra cost if you do not plan on using it more or less every day.
Because of these factors most heavy use pressure washer applications will demand a belt drive pump.
This combined with the lower rpm of the belt drive pump allows the pump to run much cooler than a direct drive pump.
First a belt drive pressure washer runs at lower revolutions per minute rpm s.
The belt drive pump crankcase has a larger oil capacity.
The gear reduction system allows for a few unique advantages to a belt drive pressure washer compared to a direct drive pressure washer.
This reduces the heat and vibration and lessens the wear and tear associated with consistent use.

Additionally belt drive s have a lower operating temperature which also contributes to its longer lifespan.
In casual or home use direct drive pressure washers are fine but industrial usage demands belt driven pressure washers for a variety of reasons.
This puts much less stress on the engine and reduces pump fatigue.
The belt drive pump crankcase has a larger oil capacity.
You d most likely find a belt driven pressure washer with our more heavy duty pressure washers.
Benefits of belt drive vibration absorption lower rpm.
Heavy use pressure washer applications will demand a belt driven pump.
They are quite large and heavy due to the parts.
Belt drive pressure washers operate using a gear reduction pulley system.
As a general rule direct drive are less expensive than their belt drive counterpart.
Belts and pulleys also absorb vibration reducing pump fatigue.

And for that there are really two major options.
The pulley system allows these pumps to turn at a much lower rpm than a direct drive pump typically 900 1400 rpm.
The pump is isolated from the heat of the engine or motor also.
Belt drive pumps turn much slower than direct drive with the rpm typically between 900 and 1400.
That s because a belt drive system requires a gear reduction pulley system where pumps turn at a slower motion.
Pumps to turn at a much lower rpm than a direct drive pump typically 900 1400 rpm.
Belt drive pressure washer rather than having the pump attached to the motor like a direct drive a belt drive pump is driven by the motor of the pressure washer by turning belts that are attached to a pulley.
This combined with the lower rpm of the belt drive pump allows the pump to run much cooler than a direct drive pump.
Belt drive power washers tend to be quite expensive to purchase.
