The CMM-1,2Fr unit is designed to clean oil-based liquids (oils, cutting fluids, working fluids for hydraulic systems of machines and equipment) from mechanical impurities. The unit ensures the purity of liquids in the production, repair and maintenance of equipment of power enterprises, construction and road equipment, engines, machine tools, process equipment, etc. The unit increases the reliability and durability of hydraulic oil systems and assemblies.

The CMM-1,2Fr unit is able to process mineral oils of the following properties:

• kinematic viscosity, mm2/s at 50°C, max – 400;
• ISO6 4406 purity class, min – 21/19/16.

Principle of operation

There are three modes of the unit operation: refilling the hydraulic accumulator, filtering the liquid and cleaning the filters. The filters are self cleaning automatically. CMM-1,2Fr determines the each operating mode duration by itself.

The parts of the unit are:

1. Pump unit.
2. Coarse (mesh) filters.
3. Fine cleaning cartridge filters.
4. Safety valve.
5. Control cabinet.
6. Hydraulic accumulator.
7. Wheels-mounted metal frame (pallet).
8. Piping.
