Vapro Multiphase Pumps
When free gas is introduced into the pump impeller, it restricts the liquid flow path and results in flow degradation. As a result, this leads to unstable production rates, pump surging and gas-locking.
Gas Separators are based on the principle of separating particles of different densities under the action of centrifugal forces. Dynamic gas separators are designed to separate free gas from the liquid by venting it to the annulus before the gas can enter the bottom stage of the pump.
Borets provides the following gas separation devices.

All Borets gas separators are dynamically balanced with three abrasion-resistant, tungsten carbide bearings to provide radial stability. All units come standard with enhanced metallurgy to provide corrosion and abrasion resistance to extend performance and run life.
The Vapro enables operation in gassy wells previously considered too challenging for ESPs. Applications such as liquid-loading gas well, CBM dewatering or increasing drawdown to enhance production rates are now viable candidates for ESP systems.
The Vapro is designed to initially reduce the size of the gas bubbles, and then change the distribution of the gas into a more homogeneous flow regime. This creates a mixture of liquid and gas that will behave similar to a single-phase fluid as it enters the primary pump. For more aggressive conditions, the Vapro can be installed above a Rotary or Vortex gas separator to reduce the amount of gas entering the unit.
The Vapro can help increase production, reduce downtime and improve ESP reliability in these gassy operating conditions.
Borets ESP systems incorporate state-of-the-art technologies spanning a wide application range.
At the core of Borets is a strong and well-developed service culture, focused on continuous improvement and customer satisfaction.
