HD SERIES

TWIN SCREW PUMPS

Screw Pumps Mod.
HD HDL HDV

Features

PERA-PRINZ® HD 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.

Especially suitable for the following industries:

Oil&Gas Shipbuilding, Naval Petrochemical, Chemical

This type of two-pair screw pump is suitable for transferring fluids and high viscosity free of suspended solids.
