NLL-H Series Pumps
Clean or very slightly polluted, low viscosity liquids without solid particles and fibers are suitable for pumping.
Technical Specifications
- NLL-H Series Pumps are centrifugal pumps that have vertical shaft, single stage, volute, closed impellers and connected to straight pipe and having their own bearings group.
- Suction and discharge flanges conform to EN 1092-2 / PN 16.
- NLL-H pumps are used by electric motors in accordance with VDI standards and IEC construction size norms
- Thanks to the removable rear design of NLL-H pumps motor, motor carriers, seal bearing, impeller can be dismantled without separating the volute off the piping.
- The direction of rotation is clockwise when viewed from above.
