Learn why two circulation pumps with similar flow, head, and power can perform differently after long-term use. This article explains CMS-Ⅱ internal design, bearing support, impeller material, motor temperature rise, vibration control, and low-noise operation.
Why can two circulation pumps with similar flow and head perform differently over time?
Two circulation pumps with similar flow and head can perform differently over time because long-term performance depends on internal structure, not only nameplate data. Key factors include impeller material, bearing lubrication, thrust bearing area, shaft wear resistance, shielding sleeve strength, motor temperature rise, moisture drainage, and vibration control.
AIKON CMS-Ⅱ improves long-term circulation performance through a PES + 30% glass-fiber reinforced impeller for models below DN65, four 1 mm circulation holes for bearing lubrication and cooling, enlarged radial bearings, expanded thrust-bearing contact area, rubber axial cushioning, integrated shielding sleeve forming, wear-resistant shaft surfaces, lower motor temperature rise, condensation drainage holes, and complete-pump noise around 45 dB under applicable conditions.
