Advantages

• Flexible adaptation to the metering task ensuring optimal metering accuracy
• The integrated injection control optoGuard^® detects hydraulic failures which can then be messaged via the optional relays
• High level of economy thanks to savings with regard to accessories such as e.g. pulsation dampeners, flow monitoring etc.
• High metering accuracy even at varying backpressure

Applications

• Highly automated processes, in particular also filling processes in all industries
• Processes where continuous metering is required such as e.g. metering of antiscalants in diaphragm engineering (smallest continuous metering volume approx. 12 ml/h)
• Metering of outgassing and high-viscosity media

Features

• Continuous or pulsating dosing
• Programmable suction and delivery stroke duration
• Pump can be adapted to the dosing media
• Integrated injection control optoGuard^® detects blocked dosing points, broken dosing lines and air or gas bubbles trapped in the dosing head
