Positive Displacement Pumps by Netzsch Pumps & Systems

NETZSCH presents their broad range of Positive Displacement Pumps for all sectors of the chemical industry for pharmaceuticals to new materials for mechanical engineering. Positive displacement pumps are a category of pumps designed to move fluid at a steady rate through a system. These pumps are able to handle viscous fluids, which flow at lower speeds and create more resistance, more efficiently than kinetic (dynamic) pumps. The main reason positive displacement (PD) pumps are not more common than dynamic pumps is because they cannot achieve the high flow rates often required for industrial applications. However, when low flow rates are adequate or preferred, PD pumps are often a better choice. They are generally more efficient for applications involving moderate to high viscosity fluids, high pressures, or variable system conditions (since changes in pressure have little effect on PD pumps). They also tend to provide consistent and gentle flow for shear sensitive liquids.
