Direct drive pumps are directly connected to the drive shaft of the pump motor or engine. Unlike belt drive pumps, direct drive pumps run at the exact same RPM of the engine with no lag of rate time. Many of these compact pumps are designed for submersible use. Common uses for direct drive water pumps include pressure washing, waterjet cutting, in air conditioners and in vacuum systems.
