ATEX Zone 0
Progressive Cavity Pump

Gerotto's solution for sludge removal inside storage tanks.

ATEX - The product is certified for working in explosion risk areas in compliance with ATEX directive.

Confined space - The product can be used inside closed environments, where human work is not  normally contemplated.

No man risk - The product doesn’t cause explosions or toxic exhalations in the working area.


Gerotto's Progressive Cavity Pump is the first pump of its kind to be certified for ATEX Zone 0, and is intended for pumping fluids and sludges even with high grade of abrasiveness. Its particular shape makes it suitable for working in every type of environment, even the most narrow.
It is equipped with a hydraulic engine and a safety system which monitors the oil pressure and temperature in different parts of the pump and cuts off the motor in case of danger.

The external structure of the pump is made of stainless steel to guarantee its resistance to wear in the case it comes into contact with corrosive and scraping materials. Thanks to this equipment, it can work at ambient temperatures between -20°C and +60°C.

The ATEX Zone 0 Progressive Cavity Pump can reach a rotational speed of 300 rpm and a capacity up to 32 mc/h.

Why choose it

The ATEX Zone 0 Progressive Cavity Pump works autonomously, which means there is no need to attach it to a Vacuum Truck: once started, it directly pumps the sludge into a removable container or in areas prearranged for waste collecting.

Unlike ATEX Zone 1 certified pumps, which have to be placed outside the tank, the ATEX Zone 0 Progressive Cavity Pump can work directly inside the tanks: for this reason sludge removal operations are more efficient and explosion risk is canceled.
