NETZSCH Pumpen & Systeme GmbH experts in solutions designed specifically for difficult pumping applications, announces the new N.Mac™ Twin Shaft Grinder, designed to protect pumps and processes. The N.Mac is designed to fragment a variety of materials, and is ideal for wastewater treatment, biogas and biomass plants, food, animal processing, and other waste and industrial applications. Available in both channel and inline (flanged) housing construction, the N.Mac can be installed into effluent channels or upstream from a pump.
Complementing existing NETZSCH product lines, the N.Mac expands grinding technology offerings, providing an upstream application to core NETZSCH pump technology. Featuring cartridge cutting knives for quick and simple replacement and servicing, the N.Mac offers quenched lubricated mechanical seals for dry running capability. The mechanical seal cartridge design – a leak free combination of mechanical seal and bearing cartridges – enables quick and simple replacement and servicing. For higher flow applications, grinders can operate in parallel, enabling partial servicing while in operation. The N.Mac can be mounted upstream before the pump (inline model) or on top of the auger (channel model). Grinders can also be stacked for successive particle size reduction. An optional control panel is equipped with an auto-reverse feature to retract jammed media.
The N.Mac Twin Shaft Grinder features modular assemblies and interchangeable components that facilitate universal parts servicing. Dual recessed and self-collapsing lifting tabs make pull-out for servicing simple. The flanged versions include cleanout and inspection ports. Dual tempered hex shafts are designed for pre-indexed assembly and even transfer of load. An exclusive shock absorption system guarantees quiet and trouble-free prolonged operation.
Models feature from 1 to 6 cutter cartridges per shaft. Cartridges come pre-assembled, with a worry-free pre-stacked spacers and blades and are available in different materials depending on the application. The cycloidal gearbox is maintenance-free for up to 2 years. The grinder comes standard with different cutting gear sizes for different shaft speeds, resulting in better grabbing and grinding.
Available accessories include a control panel to ensure operator and equipment safety, a cutter cartridge cleaner that keeps the area free to cut and allows fluid passage, and a transmission shaft extension that elevates the electric motor to above the fluid limit.
