The new Qdos 20 peristaltic pump (photo) was developed for metering sodium hypochlorite in disinfection applications with flowrates up to 20 L/h at a maximum pressure of 7 bars. The Qdos 20 peristaltic pump technology uses two tube channels where the channels are operated out of phase. The Qdos 20 reduces pulsations via alternate tube compressions, ensuring pulsation is balanced out. This results in almost continual positive fluid displacement and consistent metering of chemicals into the process. The contained pumphead design features integral leak detection, reducing waste and eliminating operator exposure to chemicals. The pump’s user interface provides control via manual, 4–20-mA, contact or Profibus control. — Watson-Marlow Fluid Technology Group (WMFTG), Cornwall, U.K.
