MD450 miniature micropump

The MD450 pump is a high-quality miniature pump for liquids that has no seal by design, eliminating one of the major failure points for conventional fluid pumps.
It is highly efficient, small, and lightweight and features an inbuilt driver beneath the blue pump end cap.

The MD450 pump is driven by a brushless drive motor with a built-in electronic controller. Constructed from precision CNC machined aluminum alloy with stainless steel tubing connectors and fitted with Viton seals as standard. Alternative seal materials and optional wetted part coatings and materials are also available, enabling this pump range to resist most chemicals and solvents. The pump uses efficient barbed connectors designed for 6.0 mm ("S" variants) or 3.2 mm ("K" variants) flexible tubing. Fitted with a fly-lead for the electrical connection as standard.
