CDMF Vertical Multistage Pump

High-efficiency in-line vertical multistage pumps in stainless steel, ideal for industrial pressure boosting and water treatment.

The CDMF series consists of high-efficiency vertical multistage centrifugal pumps with an in-line design (suction and discharge at the same level). The stainless steel construction and cartridge mechanical seal ensure high durability and ease of maintenance.

These pumps are ideal for pressure boosting systems, boiler feed, water treatment, and demanding industrial applications where reliability and energy efficiency are key.

Applications

  • Industrial processes and liquid transfer.
  • Hydraulic pressure systems
  • Water treatment
  • Agricultural irrigation
  • Alimentação de caldeiras
  • Sistemas de lavagem e limpeza
