In-Line Centrifugal Pumps, Mounted on Straight Pipe
It is intended for pumping clean or very slightly polluted,low viscosity liquids without solid particles and fibers.
It is intended for pumping clean or very slightly polluted,low viscosity liquids without solid particles and fibers.
Technical Specifications
- Centrifugal pumps with closed impellers, volute, single-stage which can be connected to a straight pipe
- Pump shaft is supported between bearings by motor bearings.
- Shaft sealing is provided by mechanical seal.
- NLL pumps are used by electric motors in accordance with VDI standards and IEC construction size norms
- Thanks to the removable rear design of NLL pumps motor, motor carriers, seal bearing, impeller can be dismantled without separating the volute off the piping.
- Suction and discharge flanges conform to EN 1092-2 /PN 16.
- NLL pumps have 32 models from DN 40 up to DN 200.
