Egger submerged sump pumps can be used in all explosion endangered zones. Together with PTB in Braunschweig, Egger has developed a safety concept specifically designed for Zone 0 explosion risks. It enables applications to be used in Zone 0 with medium temperatures up to 150 °C. Since 2000, Egger owns a valid Type Examination certificate and can rely on many years of experience in the use of submerged sump pumps in Zone 0 explosion-risk environments.
