FMI RH Series Miniature Motorless Pump Head

  • Maximum flow rate of 260ml/min
  • Easily interchangeable with a variety of pump drivers to suit many applications
  • Wide range of media can be used with corrosion resistant fluid path

The RH Series of miniature motorless pumps are available with a variety of maximum flow rates, typically 65 / 130 / 260 / 360 ml/min. The pump heads can operate at speeds of up to 3600rpm with a dispensing resolution of 0.025ml/rev to 0.03ml/rev.

RH series offer high precision flow and so are ideal for use in applications where accuracy is paramount. Head modules operate at a speeds of up to 3600 RPM

Operating pressures are from -10 to +100psig (-0.7 to +6.9 bar). Fluid temperatures are to a maximum of 100°C for models with a Ceramic and either PVDF or E-TFE wetted material. Lower temperature ratings to 60°C for models with 316SS / PVDF / Carbon wetted materials.

A broad range of fluids can be passed through the head as the wetted materials used cause an inert and corrosion resistant fluid path. The singular moving part is the ceramic piston and other wetted materials include carbon and stainless steel.
