Three-Spindle screw pumps are used for transport of viscous fluids  with lubricating properties. They are suited for a variety of  applications such as fuel-injection, oil burners, boosting, hydraulics,  fuel, lubrication, circulating, feed and so on.

Compared to [[Centrifugal Pumps]],  [[Positive Displacements Pumps]] have several advantages. The pumped  fluid is moving axially without turbulence which eliminates foaming that  would otherwise occur in viscous fluids. They are also able to pump  fluids of higher viscosity without losing flow rate. Also, changes in  the pressure difference have little impact on PD pumps compared to  centrifugal pumps.
