Universal M-Ovas® Grinding System:

Your Dependable and Diverse Friend in Grinding Things Down

NETZSCH M-Ovas® grinding systems dapat digunakan dimanapun ada kebutuhan untuk menghancurkan benda padat (solid) dengan baik, NETZSCH M-Ovas® Grinding system dapat digunakan untuk memecah padatan sehingga untuk mencegah terjadinya penyumbatan pipa serta kerusakan terhadap peralatan downstream.
Desain yang khusus dari housing M-Ovas® menjamin bahwa solids dalam wastewater (air kotor) mengalir sampai kepada cutting plate, di mana solids itu akan ditahan dan dipotong oleh bilah-bilah yang berputar (rotating blades). Housing M-Ovas® yang dirancang khusus memastikan padatan yang terdapat dalam air limbah akan terbawa menuju cutting plate, (dimana padatan tersebut akan tertahan dan terpotong oleh rotating blades) / (untuk kemudian ditahan dan dipotong/dipecah/dikecilkan dan diseragamkan ukurannya oleh rotating blades). Pemasangan yang tidak membutuhkan banyak perawatan ini (low-maintenance assembly) didesain untuk sludges (endapan-endapan) dengan aliran maksimum sebesar 300 m3/jam dan kandungan benda kering (dry matter content) hingga mencapai 7%.

Keunggulan NETZSCH M-Ovas®:

  • Keamanan operasi yang tinggi disebabkan adanya konstruksi yang kuat Kondisi operasi yang aman karena konstruksi yang kokoh
  • Mudah dioperasikan dan sederhana untuk dirawat pengoperasian dan perawatan/pemeliharaan yang mudah
  • Biaya operasi yang rendah melalui efisiensi operasi yang tinggi
  • Rasio harga/performa yang tinggi optimal

NETZSCH M-Ovas® terutama digunakan dalam bidang-bidang berikut ini:

  • Perawatan Wastewater pengelolaan air limbah
  • Agrikultur
  • Rumah jagal dan pabrik daur ulang (recycling plants)
  • Pabrik pengalengan (Canning/tinning factories)
  • Pabrik gula
  • Dapur industri


1 Housing
The housing has a hydrodynamic design with integrated stone trap for solids and a clean-out port. The sediment can easliy be removed by opening the cover plate. The housing is galvanized, optionally also in stainless steel, to ensure corrosion resistance.

2 Housing cover
The cutting unit is integrated into the housing cover. A gas strut is fitted to the cover to assist opening. This allows for easy cleaning of solids in the stone trap.

3 Cutting unit
The cutting plate is made of wear resistant, hardened steel. It provides optimum cutting performance by means of a cutting unit with a self-adjusting blade mechanism. The blades are made from wear resistant hardened steel. A flywheel supports the cutting action and reduces the driving power. It is easy to exchange the cutting plate and cutting blades and this does not require disassembly of the pipework.

4 Shaft seal
Hard metal faced mechanical seal with grease quench to prevent product leakage.

5 Drive
The standard drive unit has reinforced bearings.

6 In-line version
The product inlet and outlet are positioned on the same level. The NETZSCH M-Ovas® can be directly connected to a horizontal pipeline or to a NEMO® Pump inlet where the flange is set at 90°.


  • Applicable in biogas and wastewater areas.
  • Allowable solid content for wastewater 2 – 7% and for biogas up to 12%.
  • Different plate designs for all kinds of applications are available (norm: 26 mm comb).


  • High cutting efficiency avoids ragging of materials, such as rags, long fibers, etc.
  • The use of a 4-winged blade increased the cutting frequency.

TORNADO® T2 Industrial Rotary Lobe Pumps

The TORNADO® T2 rotary lobe pump is a positive displacement pump. The pumping action is generated by the contra-rotation of two rotors within the pump chamber which are synchronised externally. The media enters the pump chamber through the inlet port and is carried around the chamber by the rotors to the outlet port where it is discharged.


A TORNADO® rotary lobe pump fastened onto a mobile base – this is the NETZSCH TORNADO® Mobile. The concept of mounting the equipment onto a car or truck trailer makes it possible to pump large quantities of fluids with solid content, wastewater and slurries at the most unusual of sites.
