Rpm-controlled peristaltic pump for the continuous and reliable dosing of liquid chemicals.
This type of pump will reliably meter a chemical solution to the injection point particularly when low dosing rates are required with products which ‘gas off’. The advancing roller occludes the tube which, as it recovers, draws in fluid that then becomes trapped by the next roller and later expelled from the pump. The technique offers the following advantages: no contamination of the fluid or the pump as the fluid is contained in the tube, gentle pumping action with accurate flow rates, the pump is self-priming and can run dry, the pump is quiet running and very simple to handle. Adjustment of the dosing performance by a rotary knob with direct indication of the dosing performance in l/h.
