Tuthill pumps are known for their magnetically coupled, leak-free, seal-less construction and the non-pulsing flow of their external gear design.

Tuthill – Perfect for Technically Precise & Demanding Applications

Since 1977, Tuthill has worked to improve magnetically driven gear pumps by engineering solutions to meet the needs of varying applications and exacting designer specifications.

The result is a family of magnetically coupled pumps that have found wide industry acceptance for their versatility and robust standard of build and reliability.

These pumps are known for their magnetically coupled, leak-free, seal-less construction and the nonpulsing flow of their external gear design. This makes them perfect for demanding applications such as medical equipment, laboratory equipment, chemical metering, laser cooling, and industrial temperature control. If it requires a seal free, technically advanced pump, Tuthill Magnetically Coupled Pumps are the solution.

MAGNETICALLY COUPLED EXTERNAL GEAR PUMPS

The external gear design offers flow that is relatively independent of pressure providing constant fluid delivery with no pulsations. The flow will have a controlled volume that is accurate and repeatable, making it highly suitable for metering applications. The D, T, & P Series pumps can meet these demands in circumstances with high differential pressures and high system pressures, as well as thin to moderate viscosity fluids. The high volumetric efficiency is achieved by utilizing two identical gears that rotate against each other.

Benefits

  • Long Life – Up to 20,000 Hours
  • Metering Accuracy Better Than 1%
  • Continuous Fixed Displacement Flow
  • Virtually No Pulsation
  • Easy, Low Cost Installation and Start Up

Chemical Resistant Metals

A vast knowledge of magnet, pump, and motor technology is utilized in the design, manufacturing, and application of our magnetically coupled pumps.

The long life and non-pulsing flow of the external gear design are combined with the magnetically coupled, leak-free, seal less construction. Temperatures to 350°F (176°C) and viscosities from 0.3 cps to over 10,000 cps make this pump tough and reliable.
