  • Rotary Lobe Pump: What Is It and How Does It Work?

    2021-3-1 · The amount of slip in a rotary lobe pump is determined by two factors, the viscosity of the fluid being pumped and the pump’s differential pressure. To the first point, as fluid viscosity increases the amount of slip decreases, since more viscous fluids cannot slip back past the clearances in a pump’s lobes as readily as can thin fluids.
