Deep Well / Caisson Pumps

Deeply Powerful. Compact design.

PLEUGER deep well submersible pump units are designed to meet rigorous demands, offering both single-stage and multi-stage centrifugal pumps.

Standard configurations feature water-filled motors, with options for oil-filled motors to suit specialized applications. The motor sits below the pump, with the suction area located above, ensuring optimal performance. Available from 4″ motor sizes in standard designs, and customizable from 6″ motor sizes, these units are tailored to the application.

  • Single-stage or multi-stage centrifugal pumps.

  • Water-filled motors. Oil-filled option.

  • Available 4" in standard configuration or 6"+ engineered to order for specific requirements.
