TIMEX - Model MG Series -Automatic Water Filters
TIMEX MG Hydraulic Series are mid range automatic filters, ideal for remote installation sites, with a water-driven self-cleaning mechanism that doesn’t require external power source to operate. With their various screen areas the Hydraulic models support flow-rates of up to 400 m³/h (1760 US gpm), with filtration degrees of 500 down to 80 micron and inlet/outlet diameters from 2”-10”.
The Filtering Process
The filtration process begins when raw water flows through the filter inlet into the coarse screen. Here, the water is pre-filtered in order to protect the cleaning mechanism from large debris. The water then passes through the inner surface of the fine screen; dirt particles are trapped and accumulate inside the filter while clean water flows through the filter outlet. The gradual dirt buildup on the inner screen surface causes a filter cake to develop, with a corresponding increase in the pressure differential across the screen.
The Self-cleaning Process
When the pressure differential across the screen reaches a pre-set level of 0.5 bar, the Hydraulic filter’s rinse controller starts the cleaning process by opening the internal flush valve. This results in the release of a back-flush stream, flowing through the nozzles out of the hollow Suction Scanner Shaft and the Turbine to the Drainage pipe.
- Large filtration area, reliable operating mechanism and simple construction make the MG filters the ideal solution for agricultural and municipal filtration systems where no power is available.
- Automatic flushing according to pressure differential.
- No interruption of downstream flow during flushing.
- Minimal volume of reject water.
