Grinding Systems protect your installation 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 processes. The robust...

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. Objects such as stones can be easily removed from the integrated separator container with separate clean-out port and drain openings. 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...

1 Housing Hydrodynamic design with integrated stone trap for solids, and a clean-out port. The sediment can easily be removed by opening the cover plate. The housing is galvanized to ensure corrosion resistance. Available in stainless steel (optional). 2 Housing cover Cutting unit integrated into housing cover. A gas strut is fitted to the cover to assist opening. 2a This opening makes it easy to clean the stone trap. 3 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 pump inlet where the flange is...

1 Housing Housing for pipe installation to protect against pipe blockage and damage to connected equipment. 1a Housing Housing for channel installation to protect against blockage and damage to following devices. 2 Cutting unit There are different cutting blocks with special geometry for optimum crushing of the solids. To achieve the desired size reduction result, the different knife configurations with three to eleven teeth can be combined with each other. Knife configuration with seven teeth as standard. The cutting tools are hardened to increase impact resistance and sharpness, so that even...

CUTTING PLATE MACERATOR M-Ovas® The M-Ovas® cutting plate macerator for coarse materials is ideally suited for use in wastewater and biogas treamtment 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 from getting blocked or damage to downstream equipment. ■ Compact design with high throughput capacity ■ Integrated separator tank with separate cleaning and drain opening ■ Mechanical seal with grease lubrication ■ Optionally with reversing control ■ Substrates with 10-12...

CUTTING PLATE MACERATOR Combinations – 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. Functionality 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...
