SN & SM Series
ALLWEILER’s SN and SM series three-screw pumps offer decades of optimized reliability, efficiency and adaptability. The self-priming pump features hardened and polished spindles which are running in a replaceable liner. It offers a wide range of variants and applications thanks to a flexible modular system.
Hydraulic drive of the drive screws and full hydrostatic compensation of the axial thrust ensures reliable performance. The drive screw is supported either by a fluid-lubricated or by an external grease-lubricated bearing. Whether in the industrial, power, oil and gas, or maritime sectors, SN/SM series three-screw pumps are the ideal choice for demanding applications.
