BLDC Valveless Waste Transfer Pump

  • Wide flow rate range from 0.192ml/min up to 2560ml/min
  • Maximum outlet pressure of 60 psi (4 Bar)
  • Ideal for dialysis equipment, analytical instruments and clinical analysers


The BLDC pump is a valveless waste transfer pump that is ideal for OEM and medical equipment applications. It features a 24V brushless DC motor without requiring an additional driver. The pump speed ranges from 6 to 2000rpm on a clockwise rotation and is capable of providing a flow rate as low as 0.192ml/min and up to 2560 ml/min.

Suitable for a majority of medical applications, the valveless fluid control features only one moving part of the fluid path and the inert fluid paths enables maximum chemical compatibility. Internal components are sapphire-hard and constructed from dimensionally stable ceramic. Long pump life is guaranteed as it maintains calibration precision of 1% for millions of maintenance-free cycles.

Operating pressures and temperatures

Operating pressures for the pump range between 0 and 200 psig (0 to 13.79 bar). Maximum pump pressure rating is 60 psi on the outlet or 4 bar but it can withstand pressure spikes of up to 102 psi (7 bar) for approximately 10 seconds. A wide temperature range of between -20°C and 60°C allows for use within multiple different industries.
