Single Progressive Cavity Pump

Continuous volumetric dispensing independent of fluid viscosity or changes in viscosity over time gives you reliable, repeatable process control.

High-precision and repeatable are two adjective used to describe the features of GSP Progressive Cavity (PC) Pump Series. It can dispense an exact, repeatable volume of fluid as small as 0.005ml to 15.5ml per revolution. Thanks to its benefits, GSP Series is common in applications that require extremely consistent process control.

Its modular design is based on the progressive cavity principal where its core components – a rotor and stator – form a perfectly sealed metering chamber.


  • Perfectly sealed metering chamber provides excellent deposit volume assurance for improved process control with minimal fluid waste
  • Versatility to continuously dispense any fluid viscosity with low pulsation and shear allows for use in a wide range of applications
  • Suck-back feature provides clean cut-off for more accurate dispensing without dripping or drooling
  • Modular design allows for easy disassembly and cleaning that reduces production downtime required for maintenance
