Hydraulic Diaphragm Metering Pump ORLITA Evolution ProMinent
Capacity range of single-head pump: 3 – 7400 l/h, 400 – 10 bar
The ORLITA Evolution meets the most exacting safety requirements as an extremely robust hydraulic diaphragm metering pump.
It is characterised by its PTFE multi-layer diaphragm with integral diaphragm rupture warning/signalling and unique diaphragm position control.
Maximum process reliability and flexibility.
The ORLITA Evolution hydraulic diaphragm metering pump range of EF1a, EF2a, EF3a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm.
This covers the capacity range of 3 to 7,400 l/h at 400 – 10 bar.
A wide range of drive versions is available, including some with ATEX certification for use in Zone 1 or Zone 2 areas at risk from explosion.
The ORLITA Evolution product range is designed to comply with API 675.
Your benefits
Maximum process reliability:
- PTFE multi-layer diaphragm with integral diaphragm rupture warning / signalling system
- Integral hydraulic relief valve
- The new diaphragm position control protects against impermissible operating statuses (e.g. no damage in the event of a blockage on the suction or discharge side)
- The dosing precision is better than ± 1 % within the 10-100 % stroke length adjustment range under defined conditions and with correct installation
- Continuous bleeding of the oil chamber ensures reliable operation
Excellent flexibility:
- The modular and compact construction with single and multiple pump versions permits a wide range of applications. In multiple pump systems up to 5 metering units can be combined, including units with different pump capacities
Field of application
The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.
- Oil and gas industry
- Metering of reactants and catalysts in the chemical industry
- Volume-proportional metering of chemicals/additives in the treatment of boiler feed water
- Level-dependent metering of auxiliary agents in industrial production engineering, for instance hot wax metering in the production of adhesive strips
Inhibitor Metering Offshore
For smooth oil production
Our ProMinent metering pumps keep the pipework clear 24 hours a day and protect against corrosion and defects. So the oil can keep flowing.
Reliable technology is essential on a drilling platform.
ProMinent Orlita metering pumps are perfectly suited to the tough environment.
Special materials and paintwork designed for offshore applications make them incredibly robust.
And they work intelligently: the inhibitor is fed via several metering heads and can be individually adapted to every single metering volume and pump pressure.
Corrosion in the pipework and feed units is prevented.
Onshore Metering in Gas Pump Stations
Safety at the borehole
Flammable methane hydrate at the borehole can be very dangerous.
But not with ProMinent metering pumps.
By metering fluid into the drilling head, they don’t even allow methane hydrate to be produced in the first place.
ProMinent’s Orlita diaphragm metering pumps prevent methane hydrate from forming at the borehole.
Their metering heads are interconnected for even pumping pressures and volumes.
The recipe for reliable metering even under extreme conditions?
Relief valves protect against overload, bleed valves and rupture indicators automatically detect critical situations and remedy them.
