The Vertcal SERTEL NVB has the same operation mode as SERTEL NVB, but set vertically in order to be installed in a circular or rectangular pump station.

In its lower part, a grid stops the particles larger than the opening slot present in the flow, These particles are continuously scraped towards an outlet chute.


The Vertical SERTEL NVB sieves are composed of the following features, same as SERTEL NVB  :

A housing made of stainless steel with 3 mm thick sheet, assembled mainly by bolts.

The removable filtering grid, is made of 5 mm stainless steel bars, set on edge.
Minimum opening is 10 mm.

The standard length of the grid is one meter, but can be modified on request. The width of the grid depends on the flow rate, slot and water draught in front of the grid.

The length is available from 1.5 to 10 meters, by 500mm steps. The width is calculated according to the following flow rates but maximum width is 1500 mm.

Scraping system includes: an axis and two stainless steel bearings, two stainless steel chains with DELRIN rollers, between which supports are fixed carrying the metal combs.

The absence of a lower axis leaves a totally open way towards the grid.


The Vertical SERTEL NVB are particularly used in urban wastewater treatment, in every pump station all along the sanitation network to protect discharge pumps.
Easy to install, not cumbersome and requiring low maintenance.
We provide folded sheets for lateral sealing and fixation cleats.


AISI 304 L standard construction, optional 316 L.
Electrical control panel.
Receiving hopper (standard).
Reverse receiving hopper (for up-stream flow rejection of refusals)
Lateral screen basket for bypass.
ECOCOMP, SERCOMP, SERCOMP+ compactor equipped with automatic bagging system.
