Rotary Drum Screen, Wedge Wire Screen Basket, V Wire Filter Basket

Wedge Wire screen cylinders / filter drum

Filter water pipe is also called filter, water filter, commonly known as flower tube. Pumping hole (well), which is placed in the water bearing layer, can be permeable.

Wedge Wire screen cylinders can be designed with slot openings and wires running radially on the outside surface of the screen cylinder (above left) or they can be 

positioned axially on the inside of the cylinder (above right) Screen cylinders are manufactured in various diameters from 1/2" pipe size to 35" diameter. 

Screen cylinders (above right) can be fabricated into larger diameters. Each intersection of wedge wire and support rod is welded for strength and durability.

Various wedge wire and support rod combinations can be used to produce the best screen design. Rotary Screens typically use wedge wire for the screening media. 

The above externally fed unit has a spiral wound wedge wire screen drum 36" OD x 120" long.

Screen Cylinders from vee shaped wire for filtration.  A  V shaped wire is spirally wound and welded on a cage of longitudinal wedge shaped or trapezoidal 

shaped rods. Each and every intersection between vee shaped wire and the wedge wire is welded automatically. This creates a continuous spiral slot. These screen tubes 

cylinders are also known as continuous vee slot tubes.
