Sarplast GRP pipe base screens represent an innovative solution for the water wells field.
They are similar to steel continuous slot screens and couple the advantages of GRP products (corrosion resistance, easy handling and low weight) with the advantages of continuous slots screens (no-clogging and high open area).

The fiberglass pipe base screen is made of a perforated pipe, which assures optimal mechanical properties, and an external screen jacket with smooth and tapered slots which assures the desired filtering properties. The slot sizes can be between 0.5 mm and 2.0 mm and can give high open areas.

The trapezoidal slots have been designed to avoid any possible blockage of the screen. It is important to remark that the GRP surface, thanks to the smooth finish (on microscope scale) and to the absence of any corrosion phenomena, does not allow the formation of incrustation. Therefore only a very limited reduction of open area will occur during the entire service life of the screen. 

As for the casings, these screens are custom made to give the desired Collapse Resistance.
