Ritmo® 05 Ex
Ritmo®-05 Ex metering pumps in explosion-proof version are designed for dosing of liquid and gaseous media in the gas class 2B in hazardous areas of zone 1 and 2 (with the exception of gases of Class IIC – such as hydrogen; acetylene or carbon disulphide).
The explosion-proof security is based on protection class EEx p and consists
of a pump housing with Ex e approval and an Ex p control unit with rinsing
and pressure control function, proportional valve technology with automatic
leakage compensation and an decoupled PTFE pump head from the
Approval according to the EC Directive 94/9 / EC.
Classification Ex II 2G EX eb mb pxb IIB T4.
Use in the environment with the classification ATEX II 2 GD T4 (zone 1 and 2)
Housing in in IP54 version.
From Ex-housing decoupled PTFE pump head to avoid intrusion of dosing liquid or gas into the Ex-proof housing.
Flushing connection for the creation of a housing overpressure (max. 12 mbar) with air / compressed air or nitrogen (flushing volume 50 liters).
In Ex-housing integrated Ex p control unit with rinsing and pressure control function and automatic leakage compensation.
Ex-terminal box is laid out for the power supply 230 VAC.
Process capability and automation via analog (4-20mA) and digital interfaces (RS232), with interface relay and in fixed installations on Ex-terminal box.
Compressed air connection with proportional valve technology for the pressurization of the pump housing.
Pump in version R05-Ex-TH with thermal fluid is up to 120°C heatable ( Lessthan temperature class T4) or with a cooling medium cooled.
