RH Pump Head

Ceramic or Zirconia Piston & Ceramic Cylinder Liner

Ideal for Laboratory, Analytical, Industrial and OEM applications

The RH pump head stands out for its durability due to its high-quality corrosion resistant materials. Its single moving part design, minimizes drift over time, providing millions of cycles of reliable, repeatable pumping.

  • Capable of repetitive dispensing with a coefficient of variation (CV) of less than or equal to 0.5%.
  • Small displacement – fully adjustable from zero to maximum.
  • With no valves to clog or leak, maintenance and downtime are significantly reduced.
