Lex – Universal ESP

Universal ESP

We have improved the standard ESP to enhance the efficiency and reliability of Lex pumps in various well environments. Our engineering team thoroughly analyzes the incoming data to select the optimum efficiency and specific power consumption of each system (formation-wellbore-ESP). As a result, our solutions achieve the maximum efficiency and provide 30-40% runlife increase and 20-50% lower OPEX.

Universal ESP



When choosing the artificial lift method, it is essential to consider all factors that may affect the performance or safety of your equipment. The complication like low inflow, high discharge pressure, high rate, solids or high free gas content problems, viscosity, well deviation, etc., multiply failure risks, lead to unstable operation, increase downtime, power consumption, limit the well potential rate.

Lex Universal ESP systems are equally effective for low and high production, operate deeper than 10,000 ft, have a simple and compact design of surface equipment, and long runlife.

Lex Universal ESP system consists of the following components: centrifugal pump, permanent magnet motor (Universal PMM) by Lex or asynchronous motor, seal, intake, gas separator and/or gas handler, and a telemetry system. We implement the latest engineering into every system component to boost reliability in any environment, including high sand production, high free gas content, higher viscosity, or well deviation.

The product line has been optimized for any type of environment: 

Lex pumps burst pressure is up to 6,000 psi, have large vane openings and tungsten carbide bearings.

Vortex and rotary gas separators have high abrasive resistance and provide up to 95% separation efficiency.

The modular design of the seals with more than 3 mechanical seals maximizes protection from reservoir fluid entry. High-temperature elastomers have capability up to 482 °F (250 °С), thrust bearing provides high load capacity.

The Universal PMMs with a wide power range from 15 to 800 HP have high-temperature design option for the environments up to 392 °F (200 °С). They are manufactured with the use of wear corrosion resistant and coating and stainless steels.
