Screw Pumps Mod.
PERA-PRINZ® of the UD series, are externally supported twin screw positive displacement pumps. One or two pairs of screws work without making contact, ensuring a constant, pulsation-free flow rate combined with high suction capacity with very low NPSH values.
This type of two-pair screw pump is suitable for transferring fluids and high viscosity free of suspended solids.
