Q Pump Head

Ceramic Piston & Cylinder Liner

Ideal for Laboratory, Analytical, Industrial and OEM applications

The Q pump head is a reliable and versatile choice for precise fluid metering needs. Known for its high accuracy, with a coefficient of variation (CV) of less than or equal to 0.5%. Particularly notable is its ceramic piston design.

  • Constructed from durable materials like ceramics and stainless steel, its highly resistant to corrosion and compatible with a wide range of fluids.
  • One moving part – the ceramic piston minimizes wear and tear, enhancing reliability.
  • With no valves to clog or leak, maintenance and downtime are significantly reduced.
