400/M series panel mount pumps

Overview

400/MN gangable medium-flow pumps

This simple pump uses tube elements and Luer connectors for easy fitting and replacement, particularly when mounted inside instruments. Tubing is fully enclosed in the housing. Supported by ball bearings, the pump shaft ensures long motor life. It is available as pumpheads only, or with four standard, compact DC motors as well as with stepper motors.

400/M single-channel pump

One channel per pumphead, and up to four pumpheads can be ganged together on the same motor. A maximum of four channels offers great flexibility for multichannel applications.

400/N two-channel pump

Two channels per pumphead, and up to four pumpheads can be ganged together on the same motor, offering eight channels in total.
