Recirculation Pumps

El Sid 10 Watt, 1/2 Thr 12VDC Pump Product Application: Solar Domestic Water Heating Systems - Closed or Open Loop. Direct or Indirect Systems - Floor Heating Systems SID Solar PV-Powered-Circulating Pumps. Model SID-PV SID stands for static-impeller driven, which means the pump contains an electronic driver or motor that has no moving parts but simply spins on a magnetic field. The magnetic field couples the impeller and visibly drives it without any moving parts, shafts, or seals. As a result of this it has an extremely long working maintenance free life with a very low power consumption. These pumps are manufactured from bronze and stainless steel so the parts exposed to the fluid media are corrosion resistant.
