Pumps - panel mount pumps

400/A series panel mount pumps

Overview

400/A compact micro-flow pumps

For precise control of low flow rates, the 400/A is the smallest pump in our range. There is one version for continuous tubing, and another for tube elements. It is available with a range of simple DC motors as well as a stepper motor for greater speed control. It is available in black and white, or custom colors. Also available as pumpheads only.

Features and benefits

  • Flow rates from 30 µl/min to 30 ml/min
  • Instrument quality in very compact size 31 x 48 mm
  • Spring-loaded track for precision and extended tube life
  • For 0.85 mm and 0.9 mm tube wall thickness
  • Compatible with continuous tubing or tube elements
  • 12 V and 24 V DC drives with a range of maximum speeds
  • Pumphead available in standard or high pressure
