Gerotto Progressive Cavity Pump

Cleaning storage tanks in ATEX zone 0 area

The Gerotto ATEX Zone 0 Progressive Cavity Pump is developed for removing oily sediments inside storage tanks. The use of the progressive cavity pump is particularly suitable in this type of application since it is able to remove substances of different densities, sometimes very viscous, and with a high degree of abrasiveness. Thanks to its small dimensions, this machine can replace a vacuum truck, when there is not enough space to maneuver.

The ATEX Zone 0 certification of the pump guarantees the safety of operations in the presence of potentially explosive atmospheres, as no electrostatic charges are created, nor is there a danger of triggering sparks that could cause explosions. It is therefore a further important step forward in safeguarding the health of operators working in hazardous environments.
