Laing D5-Pumpe 12V D5-Vario 3/4 Moulded Barbs

The bearing is directly lubricated (wet running) by the coolant. Maintenance is hence obsolete. The rotor is always kept in position magnetically, hence small particles are not an issue. Blocking of the pump is not possible under normal circumstances. Even after longer stand-still periods a safe spin-up is ensured. The permanently magnetic rotor unit is driven by the magnetic field from the surrounding stator. The stator is completely surrounded by the stator, hence making the pump only 38mm high, barely more than the stator itself.
It hence easily fits in all common PC-, Barebone- and Mini-PC cases. A separate magnetic shielding is usually not required. The ball motor principle allows power-saving operation with comparatively high performance. By varying the input voltage the DDC pump can be adjusted over a wide speed range. All materials in contact with the coolant are corrosion resistant. This pump has 5 settings accessible via a switch. It can be adjusted from 1800 to 4800rpm.
