Progress Eco S.A. products

Welded Pro-SLOT® slotted sieves are the main and the most technologically advanced line of our products. They are reliable for using in numerous filtration processes for solid and liquid particles. We manufacture them from profiled wires of high quality stainless and acid-proof steel. The technology of electrofusion used for joining profiled wires for a set of supporting rods lets us obtain extremely precise dimensions of apertures. They work extremely well both in static structures, as well as dynamic ones, providing optimal effectiveness of a process even in tough and aggressive work environment. Depending on individual applications, our company offers flat welded or round welded sieves of different size and shape, types of fittings, with a possibility to join individual elements into larger segments.

Flat panels of wedge wire screens are manufactured by welding special profiled working wires to support wires at an angle of 90 degrees. A precise slot is received by means of applying modern welding technology between working wires and support wires. The result is a rigid screen construction with the capability of withstanding heavy loads.

Cylindrical screens are received by simultaneously winding a spiral of profiled working wire and welding them to support wires, which are arranged along the axis of the cylindrical construction. This technology allows to provide welded profile wire screens for applications where high precision of the screen together with high strength is required.

Flat sieves are flat panels of welded profile wire, fixed to a frame and adapted to assembly. Depending on the kind of application, flat sieves can be divided into: Sieves working in dynamic systems: panels to be incorporated in vibrating sieves, special reinforcement depending on the sieve load is necessary, special finishing to guarantee secure, long working time, and proper fixing. Sieves working in static systems: do not require any special reinforcements, can work as bottoms and decks in tanks and storage reservoirs and sumps.

The looped wedge wire screens have the ability to separate solids from liquids, as well as smaller materials from larger ones. These screens are constructed by putting individual wires through a machine, which loops them at a distance of 70 mm and holds them together with cross rods. This process ensures the precision of the slots and required aperture. The wires are then assembled into panels by feeding the cross rods through the loops of the wires. We produce looped screens in the form of flat and bent sheets with the possibility of additional reinforcement with fittings and fastening elements.

Curved wedge wire screens are made in both welding technologies. The specifics of the work and individual parameters determine the technology we use.

OZ type slotted tubes have a circumferential gap perpendicular to the longitudinal axis of the cylinder. Used in filtration from outside to inside. The inlet side of the filter remains smooth and easy to clean.

OZR wedge wire tubes have a peripheral slot perpendicular to the longitudinal axis of the cylinder. Used in filtration from inside to inside. The inlet side of the filter remains smooth and easy to clean.

RW wedge wire tubes have a slot parallel to the longitudinal axis of the cylinder. Used in filtration from outside to inside. The inlet side of the filter remains smooth and easy to clean.
