Oscillating Diaphragm Pump Modular Pumps for Atex Areas
Prominent’s EF3a is the first of the new Orlita Evolution pump generation to be launched. The Orlita Evolution EF3a hydraulic diaphragm metering pump together with the pumps EF1a, EF2a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7,400 l/h at 400–10 bar.
A wide range of drive versions is available, including some for use in Exe and Exde areas with Atex certification. The Orlita Evolution product range is designed to comply with API 675.
The new hydraulic diaphragm metering pump is an oscillating diaphragm pump with hydraulically deflected safety diaphragm. A specially developed diaphragm layer control system combined with the integrated pressure relief valve and temperature control reliably protect the new process pump from almost all incidents and unauthorised operating statuses. Continuous bleeding of the oil chamber ensures reliable pump operation.
The modular construction with single and multiple pump versions makes a wide field of applications possible. The new process metering pump will be used mainly in the oil and gas industry as well as the chemical industry and in industrial production engineering.
