Netzsch * Replacement Pump

Special DIAMCO NE range – 100% Netzsch NE * replacement pump

Diamco manufacture complete pumps with motor and baseframe, rotating assemblies and individual parts for all Netzsch NE Pumps NEMO®. All our replacement parts will fit your Netzsch NE serie pumps in all configuration. Originally, Netzsch pumps NEMO® NE series came with two main different types of joint, pin and gear joint style. Diamco shorten deliveries and reduce your total cost of ownership in both types of configuration.

Defined by the model number, as original Netzsch NE pumps, the Diamco NE pump series came with different style of of rotor and stator geometry. Netzsch NE70, NE69, NE90 and NE89 use the same drive end of the Netzsch NE60 and NE80 respectively in a single stage configuration. However, the “pitch” which is the geometry of the rotor and stator is more elongated increasing the velocity and evidently the flow of the media being pumped. These two models of Diamco NE pumps are specially useful where the application requires a higher GPM mantaining the energy consumption of a smaller drive end.

As OEM pump manufacturer, Diamco provide a FULL 100% warranty and reliability
