Moyno Products: In early 2013 National Oilwell Varco (NOV) acquired Moyno products, the leading manufacturer of progressing cavity pumps in the USA. Previously, NOV had acquired MonoFlo, the leading manufacturer of progressing cavity pumps in most other parts of the world. NOV now owns three of the original four licensees of the Moineau patent. The resultant company has more than 150 years of experience manufacturing and applying progressing cavity pumps in difficult applications all over the world. The combined product line, marketed under the Moyno brand in North and South America, includes more mechanical designs, covering more applications, than any other PC manufacturer. NOV/Moyno is the largest manufacturer of progressing cavity pumps in the world.

3Moyno 2000 HS (High Solids) System combines a twin screw feeder and a Moyno 2000 with a unique, patented rotor/ inlet design along with the instrumentation to create a system with high pump efficiency with low discharge pressure to provide unmatched performance in high solids sludge cake transfer. Compared to hydraulically driven, piston ram type pumps and open conveyors, the Moyno 2000 HS System requires a much lower capital investment, lower operating costs and less maintenance. Read More



Moyno Grinders include a range of different single shaft and twin shaft, slow speed, high torque grinders that macerate solids within a flow stream. Each shaft is fitted with a series of interleaving cutters and spacers to give real ‘positive displacement solids grinding. Once solids become trapped in the slowly revolving cutter stacks, the differential speed of the cutter stacks pull apart fibrous material, crop and shear plastic into small pieces and crush friable or brittle material. The Moyno Muncher has been successfully installed for over 25 years into the most difficult and industrial and municipal applications.  The Moyno Pipeliner, a single shaft grinder, is especially effective at reducing of eliminating ragging and re-ragging at municipal wastewater plants. Read More
