Grinding Systems Product Overview, Technology and Application Areas Pumps & Systems

Grinding Systems protect your installation Universal Use Grinding systems are used to effectively protect your complete installation including the pumping equipment. They ensure that over-size solids are reliably reduced to a pumpable size therefore safely avoiding the danger of blockages. Grinders and macerators are designed for the most arduous of industrial applications to prevent pipe blockage and damage to downstream equipment by reliably reducing the size of solid matter in pumped media. The extensive selection of macerating systems provides an ideal solution for many industries and...

... and are so easy to maintain: FSIP® Full Service in Place The Right Model for Every Application M-Ovas® Cutting Plate Macerator N.Mac® Double Shaft Grinder The special shape of the housing directs solid particles in the waste water towards the cutting plate, where they are held and chopped by the rotating blades. The double shaft grinders have been designed for applications where the medium contains large solid objects. These grinders are available in two different housing designs: the inline version for installation in pipelines and the channel version for installation into effluent...

CUTTING PLATE MACERATOR The M-Ovas® macerator for coarse materials is ideally suited for use in waste water treatment plants where impurities in the medium reduce process reliability. The solids in the medium are reliably macerated or separated from the medium (e.g. stones), to prevent pipes getting blocked or damage to downstream equipment. Broad range of applications The M-Ovas® should preferably be used to macerate the following media: Fibers and solids in waste water Liquid manure Substrates Hydrodynamic design with integrated stone trap for solids, and a clean-out port. The sediment...

Single mechanical seal made of hard metal with oil quench to prevent product leakage. The standard drive unit has reinforced bearings. 6 Inline Version Product inlet and outlet are positioned on the same level. The M-Ovas® can be directly connected to a horizontal pipeline or to a NEMO® pump inlet where the flange is set at 90°.

Wear resistance With the cutting plate macerator the crushable parts are either pressed to the cutting plate or partially drawn into the holes of the cutting plate by the flow. Larger particles jam in front of the cutting plate and are crushed by the cutting head until they can be flushed through the openings of the cutting plate. The cutting plate consists of a wear-resistant special alloy, is hardened and finely polished on the contact surface to the cutter head. The cutter head is made of steel with positively shaped carbide cutting edges. In case of wear the (1 cutting plate can be...

MANY OPTIONS POSSIBLE The medium with solid or fibrous parts is continuously sucked into the M-Ovas® by a self-priming NEMO® progressing cavity pump or TORNADO® rotary lobe pump arranged behind the macerator. The solids are crushed or remain in the stone trap below the cutting unit. This protects all downstream units. M-Ovas® cutting plate macerator, horizontally connected to a TORNADO® rotary lobe pump. M-Ovas® cutting plate macerator connected to a NEMO® pump inlet with the flange set at 90

N.Mac® Inline DOUBLE SHAFT GRINDER FOR IN The double-shaft grinder N.Mac® is capable of fragmenting large and solid particles in liquid media. It is the ideal equipment to suit different applications such as wastewater treatment, substrates or food and fruit scraps for biogas plants. The inline housing allows installation in piping systems to protect downstream equipment, such as pumps. Your benefits Double shaft technology for size reduction of solid particles Energy efficient motors, from 2.2 - 4 kW Low speed of the cutters with high torque Standard cutter arrangement with 7/7 teeth...

R INLINE INSTALLATION Cutter cartridges Wear resistance Specific cutter geometries for each type of solids facilitate the particle reduction process. To reach the required particle size the different cutters with 3 to 11 teeth may be combined accordingly. The cutters are thermally hardened to increase resistance and sharpness assuring reliable grinding of the toughest solids. Flow rates und dimensions Dimensions (mm) Flanges (ANSI/DIN)

N.Mac® Channel DOUBLE SHAFT GRINDER FOR CH Also in the channel version, the N.Mac® double-shaft grinder is ideal for fragmenting large and solid particles in liquid media and suits various applications such as wastewater treatment or grinding of food and fruit scraps. This housing design allows installation in sewers to avoid blockages and by crushing foreign substances. Double shaft technology for size reduction of solid particles Energy efficient motors, from 2.2 - 4 kW Low speed of the cutters at high torque Standard cutter configuration with 7/7 teeth Optional control unit with reverse...
