M-Ovas® Universal Cutting Plate Macerator

M-Ovas® Universal Cutting Plate Macerator

Reliable grinding of impurities to protect pump systems and equipment

Grinding systems protect your system. With the universally applicable M-Ovas® cutting place macerator, you can prevent possible damage to your pump caused by impurities. The individually adjustable cutting place prevents the entry of substantial solids into the following systems such as pumps. It is ideal for use in biogas or wastewater plants.

Impurities are reliably ground up or separated from the medium. Objects such as stones can be easily removed from the integrated separator container with separate clean-out port and drain openings. This reliably prevents damage to the following aggregates. The crushable parts are pressed against the cutting place by the flow and ground there by the rotating head of the cutter until they are flushed through the openings and do not pose a danger to your system. The cutting plate is convincing due to its robustness. It is made of a wear-resistant special alloy, hardened and finely ground on the contact surface with the cutter head. Available in different hole sizes for the individual requirements of your application, the steel milling head is equipped with positive-fit carbide cutting edges. In addition, the cutting plate can be turned over in case of wear. Thanks to the quick and straightforward disassembly, you save time as well as money while at the same time ensuring maximum protection for your pump.

M-Ovas® Universal Cutting Plate Macerator

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.

3 Cutting unit
The cutting plate is made of wear resistant, hardened steel. Optimum cutting performance through cutting unit with a fixed cutting mechanism. Cutting head and cutting blades made from wear resistant hardened steel. The flywheel effect of the cutting head supports the cutting process and reduces the drive power. Easy exchange of cutting plate and cutting blades without disassembling the pipework. A manual adjustment is not necessary due to the pressure spring support.

4 Shaft seal
Single mechanical seal made of hard metal with oil quench to prevent product leakage.

5 Drive
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 pump inlet where the flange is set at 90°.
