MAGSON MML & MMT

Stainless steel magnetically centrifugal pumps

For applications involving higher pressure and temperature requirements.

  • Two performance ranges: MML up to 500 l/min, MMT up to 80 m delivery head
  • Hermetically sealed: Magnetic coupling without dynamic shaft seal
  • up to 300 °C: Maximum fluid temperature for the MMT, depending on the model

Hermetically sealed

Magnetic coupling without a dynamic shaft seal

Low-maintenance

No mechanical seal that needs to be replaced regularly.

Resistant to pressure and temperature

Metal versions for process conditions that exceed the typical limits of plastics.

Flexibly designed

Materials, motors, and connections tailored to the application.

Quick Selection

Which stainless steel pump is right for your operating conditions?

The design matters: The MML model handles higher flow rates. The MMT model achieves high discharge heads at low flow rates and can handle gas-laden fluids.

MAGSON MML

For continuous process conveyance at higher flow rates, as well as at elevated temperatures and system pressures.

  • Flow rate: 500 l/min
  • Head: 24 m
  • Fluid temperature: 150 °C
MML in Detail

MAGSON MMT

For low flow rates at high heads of up to 80 m, gas-saturated liquids, as well as mixing and high-temperature processes.

  • Flow rate: 10 m³/h
  • Head: 80 m
  • Temperature: maximum 300 °C

Material Selection

When to Use Stainless Steel Instead of Plastic?

MAGSON metal pumps are used when temperature, pressure, or specific material requirements preclude the use of plastic.

  • Corrosive media at elevated temperatures
  • Processes with elevated system pressure
  • Fluids with special metallurgical requirements
  • Crystallizing or gas-laden liquids
  • Chemical, pharmaceutical, food, laboratory, and cooling processes
Have the application reviewed

Higher flow rates

MAGSON MML

The normal-suction MML combines a seal-less drive concept with an efficient spiral casing. Four model variants cover operating points up to 500 l/min and a head of 24 m.

  • Stainless steel 1.4408 / AISI 316L as standard
  • Up to 150 °C in the standard version
  • System pressure:
    • BG1–BG3 16 bar,
    • BG4 15 bar; optional 25 bar
  • IEC-standard motors and variable-frequency drive operation
  • ATEX version available

Small volumes, high discharge heights

MAGSON MMT

The MMT is a magnetically coupled peripheral impeller pump. Its steep performance curve makes it easy to set the operating point and makes it particularly suitable for low flow rates and high heads.

  • Up to 10 m³/h and 80 m head
  • Up to 25 bar and 300 °C
  • Can handle gas content up to 20%
  • Standard or API configuration
  • ATEX versions available upon request
