12. Explosion-proof dosing pumps (ATEX)

12.1 General

The explosion-proof version of the MEMDOS E dosing pump is an electric motor-driven, explosion-proof 
diaphragm dosing pump of equipment category 2, group II.
In combination with an explosion-proof motor (Ex II 2 G E Ex e II T3 or Ex II 2 G E Ex d/de IIB/IIC T4) it is used 
for dosing fluids Zone 1 hazardous areas. The dosing pump carries the Ex mark "Ex II 2 G c k T4 03 ATEX 
D085".

ATTENTION!

The dosing pump is not intended for dosing gaseous media or solids.

DANGER!

Fire hazard. Shock wave: parts may fly off and cause fatal injury. MEMDOS DX must never be used in areas 
with a potentially explosive atmosphere.

12.2 Special conditions

The minimum requirements for the zone classification must be ensured if using the dosing pump in areas 
with a potentially explosive atmosphere. The dosing pump itself and the motor must meet the minimum 
requirements.

12.3 Dosing of flammable media

If dosing flammable fluids, all metal parts in the suction and discharge pipes must be grounded to prevent 
electrostatic discharge.
Stainless steel is recommended for the dosing head.
Dosing pumps with diaphragms more than 90 mm in diameter are equipped with special conductive dia-
phragms to prevent static charging. When obtaining replacement parts, order original diaphragms only.
