How does the flow rate of the LubeDrive change when pumping gear oil?

The LubeDrive operates on the positive displacement principle, which means that the delivery capacity increases in direct proportion to the drive speed. Whilst we recommend using the first gear setting on the cordless screwdriver for highly viscous media such as grease, the second gear setting can be used for less viscous media such as gear oil. Due to the lower Viscosity of the medium, a lower torque is required, allowing the Pump to be operated at a higher speed.

Practical tests have shown that when pumping gear oil with the LubeDrive, a flow rate of approx. 5 to 6 litres per minute can be achieved. The actual delivery capacity achievable also depends on the speed and available torque of the cordless screwdriver used.
