HMS Ciris Borehole submersible pumps

HMS Ciris Borehole Submersible Pumps


The HMS Ciris pumps have been engineered in accordance with the modern requirements to energy efficiency and reliability, taking into account heavy duty operation with unstable power supply quality.

The HMS Ciris pump consists of a single or multistage single-entry pump and a rigidly coupled rewindable water-filled electric motor.

The pumps are distinguished by reinforced casing parts that significantly reduce the risk of mechanical damage during transportation, installation, operation and maintenance.

  • Built-in non-return valve prevents water hummer and reverse rotation.
  • High-strength corrosion-resistant stages made of the thick stainless steel tubes.
  • Stainless steel corrosion-resistant casing straps provide overall structural rigidity.
  • Durable plastic impellers reinforced with stainless steel (patented design).
  • Pumps of 8’’ pumps can bear plastic or stainless steel impellers.
  • Pumps with capacity over 100 m³/h are completely stainless steel.
  • Stainless steel corrosion-resistant shaft.
  • Octagonal bearings provides better removal of the sand particles.
  • Expelling vanes for impellers unloading from axial forces (extends lifetime of a thrust bearing in the motor).


  • Sand guard keeps motor free from sand particles.
  • Mechanical seal isolates the motor from the pumped media.
  • Graphite-based radial bearings with helical grooves for improved lubrication.
  • Motors are filled with a potable-water-friendly liquid and may be stored at temperatures down to -30 °С.
  • Motors can be refilled with clean fresh water during maintenance.
  • High-temperature (PE2/PA) motor winding wire (up to 100 °С thermal stability).
  • ”Squirrel-cage” high-reliable copper rotor provides more efficient operation compared with aluminum one.
  • Increased length of stator and rotor enhances reliability and cooling conditions to withstand bad voltage quality.
  • Stainless steel corrosion-resistant shaft.
  • Reverse trust bearing prevents rotor’s vertical displacement.
  • Self-aligning water-lubricated thrust bearing ensures reliable and trouble-free operation.
  • Rubber membrane compensates the liquid thermal expansion inside the motor at operation.
