HovaCAL® PP is a standalone dosing unit for water and aqueous solutions and is based on a precisely regulated peristaltic pump, combined with a flow rate sensor. This adjusts for the effects of aging or counterpressure influences which generally have an adverse effect on peristaltic pumps. The specified flow rate is approached in a precise fashion. HovaCAL® PP is suitable for all applications requiring the robustness of a peristaltic pump and the precision of a thermal flow meter. The HovaCAL® PP can perform any dosing task with high precision, regardless of whether the fluid is dosed in an evaporator or a different process.
