Does pump lose pressure when refilling gearbox?
When pumping any material 300 ft. vertically, there will be pressure losses. We also experience pressure losses due to friction loss in the hoses. However, this is not a negative thing. Our modified diaphragm pump can pump up to 1000psi. The user would not want to introduce oil into the gearbox at such a high pressure, so the pressure drop due to vertical distance and friction inside the hose allows the gearbox to be filled at a manageable pressure and flow rate.
