Overview

400/MN gangable pumpheads

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.

400/M single-channel pumphead

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 pumphead

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

Features and benefits

From one to eight channels in a compact design
400/M works with 1.6 mm wall thickness tubing and Luer connectors
400/N works with 1.0 mm wall thickness tubing and barbed fittings
Complete pump with motor, or as pumphead only
Pumphead available in PVDF for greater chemical compatibility
