Screw Pumps Mod.
HR & HRV
PERA-PRINZ® screw pumps of the HR series, are externally supported and positive displacement twin screw 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-screw pump is suitable for transferring high-viscosity fluids free of suspended solids.
