Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Laboratory Instruments. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

Product structure 1. Automatic drain valve 2. Electric motor 3. Pressure indicator 4. Water outlet 5. Water inlet 6. Screen 7. Suction nozzle Product principle The water flows through the screen and the particles are retained on the inside of the screen of the filter element.

The filtered water then flows out through the outlet. Self-cleaning mode can be started by pressing, timing or manual three ways, following the principle of pressure difference.

When the internal and external pressure difference reaches the set value, the self-cleaning mode starts.Drain pipe hydraulic valve open, sucking the scanner to produce negative pressure suction nozzle inside, absorbing impurities, at the same time sucking scanner in under hydraulic motor along the inside surface mesh do reciprocating screw, movement, no cleaning blind area, impurities by the discharge outlet.

The cleaning time of self-cleaning filter is set by the controller in advance, the drain valve is closed after cleaning, and little water loss in cleaning process.

Technical parameters ≥ Single maximum filtration flow up to 1200m3 / h ≥ Filter optional drilling (4000-800μm), wedge (1000-50μm) woven composite (800-20μm) ≥ minimum working pressure ≥ 0.1. Mpa (sewage valve for the electric ball valve) ≥0.18.

Mpa (discharge valve for the electromagnetic diaphragm valve) ≥ Maximum working presure ≤ 1.6MPa (special customizable) ≥ Operating temperature ≤ 65 ºC ≥ Power: 380V / 50.

Hz ≥ Cleaning method: suction type ≥ Cleaning time: 10-200 seconds adjustable ≥ Control: pressure, time, manual and PLC Filter material Shell: carbon steel, 304 stainless steel, 316L stainless steel Screen: 304 stainless steel, 316L stainless steel Drain valve, cast iron,copper,stainless steel,PVC,nylon Controller: PVC, aluminum Seal ring: EPDM rubber Suction: stainless steel, PVC Loss of pressure table DLX-FW series self-cleaning filter specification table Model Water in/outlet (mm) L (mm) L1 (mm) L2 (mm) H (mm) Power (KW) Max flow (m3/h) Weight (Kg) DLX-FW- DLX-FW- DLX-FW- DLX-FW- DLX-FW- DLX-FW- DLX-FW- DLX-FW- Packing&Shipping Company Infom
