EN733 End Suction centrifugal Pump NESO

NESO series pump is a kind of horizontal single-stage, end suction centrifugal pump, which is designed & manufactured according to EN733/DIN24255 standard. This standard covers both performance and dimensions. Available pump discharge size is from 32mm to 250mm, working pressure is up to 16 BAR. The volute pump casing is fitted with replaceable wear ring and has a suction vane to give smooth flow into the double shrouded hydraulically balanced impeller. Pump is made in cast iron as standard, other materials are also on options. Its “Back Pull Out” design allows the removal of the complete rotating element without disturbing the pipework. This feature enables quick and easy maintenance. This series pump is long coupled model, fitted with IEC standard electric motor on a baseplate though the suitable coupling with guard.
Description
