Diaphragm metering pumps Ritmo®05 Ex are designed for use in hazardous areas of zone 1 and 2
All wetted components are manufactured in Full-PTFE and guarantee an ultimate chemical resistance.
Positively controlled valves ensure a perfect seal and metering accuracy. The pump head is decoupled from the explosion-proof housing and avoids any penetration of fluid or gas in the pump housing.
The explosion-proof design is based on the EEx p in accordance with EC Directive 94/9 / EC.
The external control and automation capability under hazardous conditions is ensured by Start / Stop, via an analog interface 4-20 mA and digital interface RS232. Ex-engineered interface relays in an Ex-terminal box decouple the input signals from the pump.
