This highly economical and substantial small-capacity series is ideal for extensive applications requiring high-precision and durability.

This compact metering pump comes with five types of pump heads as a quick response to differing site operating conditions and pump applications. Available are models that reliably answer an extensive range of needs including injection of trace amounts, high-pressure injection, and metered injection of high-viscosity liquids or liquids containing slurry. Moreover, multiple-series pump models and pulseless models further extend the scope of application of this series.

<Features>
  • Rigid oil-bath type drive
  • Available in both vertical and horizontal models for selection according to conditions of use and installation
  • Duplex, triplex, and up to six in-series pumps can be manufactured. (also connectable to R series)
  • Liquid-end materials have been specially selected to meet all kinds of liquid injection needs.
