Strainer
To remove particles and foreign matter from the water flow supplied to all areas of an underground mine.
- The Inline Strainer, which has a fixed element and has to be manually cleaned by removing the cap
- The Sweep Strainer, which is also an inline strainer but includes a backwash facility to sweep small particulate matter off the strainer element. The dirt is removed by operating a handle which ‘sweeps’ a dirt collection shoe over the entire strainer element surface and discharges the dirty water to drain
- The HPE strainers use stainless steel wedge wire strainer elements. Due to the taper profile of the wire, it has a narrow gap on the upstream side of the element and a progressively widening gap on the downstream side, it reduces the tendency of the element to clog. Filtration is available from 1000 to 3000 micron
- Stainless steel internals
