SPGL Type Manual Drainage Water Filtering Machine SPGL type manual drainage purifier consists of a high quality carbon steel tunnel body, a special-structured stainless steel cuneiform filtering web, a water-pilot valve and a drainage equipment. When the purifier operates, the water-pilot valve is open the water flows into the purifier and out of the exit. When draining, the water-pilot vale is closed while the drainage valve is open, the water flows through the filtering web, part of which flows back into the system, another flows out of the drainage valve, automatically creating a back flush. The whole system works properly without any pause.

Technical Characteristic

1. High filtering precision: wide range of filtering substance diameter 0.5-5mm.

2. Huge capacity of filtering: low pressure loss, huge water processing capacity, maximum: 7000m/h.

3. Long service life: consisting of a stainless steel cuneiform filtering web and a high quality carbon steel tunnel body.

4. Low integrate cost: no need of removing or changing of the filtering web, long service life.

5. Easy to operate and highly efficient: no accessory tunnels needed, good back flush effect.
