The MicroBlue can be mounted in any orientation. Its Gyrok Technology enables the Blue Diamond to efficiently pump wet and dry simultaneously, eliminating the risk of burning out and failing. MicroBlue is also a dual voltage pump which uses proven thermistor level sensing technology to remove the risk of stuck or sunken float switches. MicroBlue is also UL plenum rated and backed by Blue Diamond’s standard market leading three year warranty.
The patented GyRok pumping principle employs a elastomeric conical ( silent while pumping ) diaphragm displaced by a number of legs positioned annularly around a nutating drive element. The legs provide control of almost the entire diaphragm, giving outstanding self-priming characteristics. It’s very popular with Mini-Split MFG’s.
