The Granzon PWM DDC Style Pump w/ Digital Display is a DDC style pump with multiple digital display read outs. Highlighting the display readouts is a tachometer design, real time display of pump speed. Speed control can be set manually in increments of 100. Automatic mode is also available when using your motherboards PWM header. Flow rates, voltage and load are displayed as well for a complete overview of your pumps performance. Keep in mind the flow rate is based on the pumps speed. This means the lower your loop resistance the more accurate the reading will be. For most applications it will be a very accurate simulation.
This pump is NOT a stand alone unit. It must be installed on compatible device for use. Not responsible for any hardware damage. Use at your own risk.
