The MCFM series filter removes dirt particles as water flows through the coarse and fine screens to the outlet. The PLC controls the self-cleaning modes required according to type of dirt and dirt loads. The self-cleaning cycle modes include:
- Continuous flushing
- P and time triggered
- P flushing
In the flush mode, the drain chamber is always open releasing a continuous flow of a small quantity of water to the atmosphere through the continuous flushing drain valve and the super flush valve. Input from P and H P switches opens these valves.
The continuous flow of water forces a steady back flush streams through the fine screen and into the environment via the back flush nozzles, collector pipe and drain chamber. The booster pump delivers filtered water to the hollow shaft of the collector pipe and to the injection nozzles, which inject a jet stream onto the fine screen. The electric motor causes the collector pipe and nozzles to spin, while the piston pushes the collector pipe back and forth. This helical motion together with the backflush and jet streams ensure 100% cleaning of both sides of the fine screen.
Note: The back flush process also operates at time-triggered intervals in combination with inputs from P and H P switches.
Features:
- Easy to install, operate and maintain
- Line pressure operation – even low pressure
- High flow rates in a compact design
- 100% cleaning on both sides of the fine screen
- Hydraulic or electric control
- Short payback period
