Hydraulic Diaphragm Metering Pump Orlita® Evolution by ProMinent

Orlita Evolution

The hydraulic diaphragm metering pump Orlita® Evolution sees the dawn of a new era in ProMinent’s process pumps product range. The EF3a is the first of the new Orlita® Evolution pump generation to be launched. It was unveiled for the first time at ACHEMA 2015.

High-process reliability and flexibility

The hydraulic diaphragm metering Orlita® Evolution hydraulic diaphragm metering pumps form an integrated product range with stroke lengths of 15mm to 40mm. This covers the capacity range from 3l/h to 7,400l/h at 400bar to 10bar. A wide range of drive versions is available, including some for use in Ex-zones 1 and 2. The Orlita® Evolution product range is designed to comply with API 675.

The Orlita® Evolution meets the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump. It stands out thanks to its PTFE multi-layer diaphragm with integral diaphragm rupture warning system and unique diaphragm position control. Its modular construction offers extremely good flexibility in terms of applications.

Heidelberg-based ProMinent uses a specially developed diaphragm position control combined with the integrated pressure relief valve and temperature control to reliably protect its new process pump from almost all incidents and unauthorised operating statuses.

Metering reproducibility was found to be better than +/1% with a stroke length of between 10% and 100% under defined conditions and after proper installation. 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. Up to five metering units, with the same or different pump capacities, can be combined in multiple pump systems.

For maximum flexibility, the customer can choose seven different gear reductions and decide whether the drives are arranged vertically or horizontally. On request, ProMinent can customise the pump.

Certified for tough jobs

The four product ranges of the new family of process pumps comply with API 675 and provide a capacity ranging from 3l/h to 7,400l/h at 400bar to 10bar. ProMinent has a number of drive variants for use in areas at risk from explosion (zones 1 and 2 with ATEX certification).

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.
