DC Pumps

Panasonic variable speed centrifugal pumps are designed for circulation of circulation of liquids (hot/cold water and brine water). These small, non-self-priming pumps range up to 14m head and 90L/min capacity. The variable speed capability enables improved efficiency over the full range of operation.

Specific applications include residential hot water circulation, sanitary water supply*1 and others*2.

The pumps are driven by Panasonic designed and manufactured DC brushless motors enabling consistent quality, compact size and customization. The precise control of the pumps are available using pulse width modulation (PWM) or analog signal and feedback signal of rotation speed. All pumps listed here are compliant with ErP directives in Europe.
