Submersible pumps

Abrasive and corrosion resistant submersible pumps with single-seated and double-seated support impellers design are used for efficient lifting of reservoir fluids:

  • For oil production;
  • For reservoir pressure maintenance.

Intended use:

Submersible centrifugal pumps are supplied in size groups from 362 series to 538 series with capacity from 125 to 9,500 barrels per day. A wide range of pumps allows equipment selection for all possible operations conditions.

Submersible centrifugal pumps produced by New Technologies LLC are used to lift reservoir fluids (mixture of oil, associated water and oil gas) both in normal and complicated operational conditions. Pumps are produced in sections connected as «flange-casing». Pumps consist of a head module and a top section (with a discharge head to connect a pump to tubing), middle sections, an intake module, a gas separator (defined at the time of order placement), back pressure and bleed valves.

Check valves are tight sealed, which allows the customer to perform tubing pressure integrity testing.

Check valves are tight sealed, which allows the customer to perform tubing pressure integrity testing. Pump sections might have different length, providing for optimal pump selection to any well. Thrust bearings are installed along the entire length of each section. Pumps robust and continuous operation in various operation conditions is ensured by optimal distances between radial bearings.

Options

  • Pumps with axial thrust bearing;
  • Pumps without axial thrust bearing;
  • Pumps without axial thrust bearing with packaged assembly design;
  • Water injecting pumps used in a reservoir pressure maintenance system;
  • Pumps for units with two ESPs.
