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.Water outlet 4:Water inlet 5:Screen 6:Cleaning brush 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.

When the particles accumulated to a certain number and the pressure differential increases to the pre-determined level, the flushing cycle starts. It include two steps: First, the automatic drain valve opens on the drainage outlet.

Then, electronic motor drives the cleaning brushes which are inside the screen, the solids are expelled through the drain valve.

Filters continue to supply filtered water even during the flushing cycle.The whole working system is controlled by a smart box which has several control modes: pressure differential, time, manual and PLC.

Technical parameters A single maximum flow capacity is up to 4000m3 / h Wide filtration range:screens from 4000 to 20 microns Working pressure(min)≥0.18.

Mpa Working pressure(max)≤1.6MPa(customized is available) Working temperature ≤65ºC Power supply: 380 v / 50 Hz (Customized is availabel) Cleaning method: brush type Adjustable cleaning time: 10-200 seconds Filter material Shell: carbon steel, 304 stainless steel, 316L stainless steel Screen: 304 stainless steel, 316L stainless steel Brush holder: 304 stainless steel, 316L stainless steel Drain valve, cast iron,copper,stainless steel,PVC,nylon Controller: PVC, aluminum Seal ring: EPDM rubber Cleaning brush: stainless steel, nylon Loss of pressure table 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) DLD-FW- DLD-FW- DLD-FW- DLD-FW- DLD-FW- DLD-FW- DLD-FW- DLD-FW- Packing&Shipping Company Infomation
